Ian Curtis eb798ed15e Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle) 2017-10-05 19:15:00 +00:00

Ian Curtis 0afd9026dc Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value. 2017-09-26 00:30:08 +00:00

Ian Curtis 7590f50350 cannot specify explicit initializer for arrays - fix for visual studio 2017-09-24 22:03:31 +00:00
Bart Trzynadlowski 55bb02d4e5 - New work-in-progress frame timing code (disabled by default, compile with NEW_FRAME_TIMING defined to activate it) 
- New JTAG emulation, moved into its own class, CJTAG
- Removed game-specific sun clamp hacks from CNew3D (JTAG and Real3D emulation will call the appropriate method to configure this at run-time)
- Removed JTAG from Real3D save state data and reused some of that space for new state variables having to do with the internal JTAG-based config as well as new frame timing state variables

Ian Curtis a3e2fb7906 Calculating the length of the vertex results in quite broken values for fogging when the vertices are traversing the view frustum. The hardware also wouldn't have been doing a square root per vertex for fogging. Simply using the z values is enough. Todo check clamping of values for the near/far planes. 2017-09-06 13:07:39 +00:00

Ian Curtis 165926aa06 Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions. 2017-08-29 10:27:29 +00:00
Bart Trzynadlowski f04a285727 DMA and register space access for Real3D have been unified and CReal3D::ReadRegister() returns little endian data now that the PowerPC handler byte-swaps back, to be consistent with how DMA registers work. 2017-08-29 01:28:21 +00:00

Ian Curtis cd5978773a Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade. 2017-08-19 20:06:31 +00:00

Ian Curtis 0efd4dac39 Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading. 2017-08-15 23:21:57 +00:00
Ian Curtis b1cc9a615d With fixed shading, when lighting is disabled, fixed shading appears to be a flat shaded version based upon the poly colour, instead of per vertex attributes. 2017-08-15 20:50:36 +00:00

Ian Curtis 5709ee2659 Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware. 2017-08-09 16:56:56 +00:00

Ian Curtis 3fc28159eb Add the unclamped light model we know exists to the shaders. 2017-08-03 10:41:18 +00:00
Ian Curtis b1bd877b82 Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway. Thanks to Harry for finding this bug :) 2017-08-01 23:48:53 +00:00
Ian Curtis 9aa3f13777 We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model. 2017-07-29 16:30:30 +00:00

Ian Curtis 3efb055344 Clamp the ambient light to a max of 0.75. LA Machine guns seems to use an ambient value of 1, which is full bright for everything. But for some reason the hardware seems to treat this as ~ 0.75. This fixes various missing shading in the game. This doesn't seem to have any negative effects on other games I have tested. Clamping in the shader as we might need the full range of values for fixed shading. 2017-06-29 19:05:30 +00:00

Ian Curtis 97781108e8 A second go at fixing the fixed lighting in star wars .. Fixed shading is per vertex poly colours. For some reason in star wars they are treated as unsigned values instead of signed, like in every other game. These polys are all marked with specular enabled, where as in the rest of the games they are missing this flag. That's the only difference I can find. 2017-06-21 17:04:53 +00:00

Ian Curtis 3c78571615 There are 2 bits in the polyheader labelled discard. When both are set ie in sega rally, the polygons are totally discarded. Scud seems to set bit 1 which seems halve the opacity. 2017-04-15 19:00:46 +00:00
Ian Curtis 21836c088c The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded. 2017-04-14 23:41:11 +00:00
Ian Curtis fc50bdee98 light parameters must be clamped (HarryTuttle) 2017-04-14 00:08:17 +00:00
Ian Curtis 391aafd4c1 Virtua fighter has a few massive polys that shouldn't be visible. It looks like these polys have a bad matrix, but the node distances are all zero. This means the bounding box that encapsulates them is of size zero. Skipping over these entirely seems to fix the issue. 2017-04-12 15:47:57 +00:00

Ian Curtis 17f878421b Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :) 2017-03-24 13:38:20 +00:00

Bart Trzynadlowski 61159c07f8 Added 8- and 16-bit tilegen VRAM access handlers to fix missing columns in Star Wars Trilogy tilemaps. Thanks to Spindizzi for initial confirmation that this was the problem. 2017-03-23 04:22:25 +00:00

Ian Curtis 9780f333b4 The model3 has this weird issue where the 2d and 3d planes are misaligned by 2 pixels. Originally I made a quick hack that shifted subviewports 2 pixels. But apparently that wasn't enough, as the issue effects everything. Thanks to HarryTuttle for pointing this out, and making a patch :) 2017-03-19 01:33:45 +00:00
Ian Curtis b19ceb0b6a Texture coordinates seem to be scaled relative to the fixed texture size of 256. Thanks to HarryTurtle for figuring this crazy logic out. The road in scud matches the arcade now almost perfectly. 2017-03-13 00:59:35 +00:00
Ian Curtis dcd018ab7e Change microtexture scaling values. Seem to much better match expected output. (thanks HarryTuttle) 2017-03-12 19:00:00 +00:00
Ian Curtis 732e3ef51f More fixes to microtexture coordinates. They go vertically up and down the texture sheet, and not horizontally as I had guessed. (Thanks HarryTurtle) 2017-03-11 12:55:47 +00:00
Ian Curtis 6636776f03 Fix microtexture texture coordinates (thanks HarryTuttle) 2017-03-11 01:18:43 +00:00
Ian Curtis 503c88df11 fix the bad projection matrix in dirt devils and lost world 2017-03-07 01:29:07 +00:00
Ian Curtis f173c3c3ce The hardware actually seems to treat the quad primitive as a triangle strip. The winding order can actually change between the first and second 'triangle' inside the quad, leading our code to incorrectly backface cull the 2nd triangle. So we must re-calculate the winding order for the 2nd triangle. This fixes a massive missing poly in the road in la machine guns, probably other games too. The hardware is unaffected by the winding order, as it doesn't calculate the poly normal from the vertices directly, instead it uses the provided normal in the poly header. 2017-02-21 23:35:40 +00:00
Ian Curtis 5b9741bd5d Support high priority polygons. They are treated as a separate overlay plane by the h/w. Fixes some missing fx in harley. 2017-02-20 17:22:32 +00:00
Ian Curtis 2ae2010ee4 Add high priority poly function. Used by harley. 2017-02-18 23:58:08 +00:00
Ian Curtis 4a116190b5 When the translator map?? bit is enabled the colour format seems to be 4-5bit. Max observed value is 16. Scaling these values up seems to produce the correct colours in harley and dirt devils. 2017-02-16 17:20:42 +00:00
Ian Curtis 7407d03036 Put a check in there, in case near values come out really close to zero. Fixes a slight corner case in lemans24. A check probably should have been there originally :) 2017-02-08 16:14:50 +00:00
Ian Curtis 24cbeed526 Dynamically calculate near/far frustum planes for each viewport priority layer by clipping the overlapping meshes with the 4 frustum planes. A bit brute forcy, but the results are great. 2017-02-07 14:05:03 +00:00

Ian Curtis 707e945db9 delete unused files 2016-12-09 14:15:11 +00:00
Ian Curtis 2c23268d88 Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess. 2016-12-09 14:13:46 +00:00
Ian Curtis da8b63b44b The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space. 2016-12-06 14:39:46 +00:00

Ian Curtis 665fa90425 Get clipping planes directly from the viewport data. Also no need to clip against a far plane 2016-11-26 01:12:08 +00:00
Ian Curtis 54c405709f Need to walk back in memory and check the previous texture tiles to see if they overlap with the current textures being invalidated. If they overlap they must be cleared too. Algorithm is a bit brute forcy and more expensive than I'd like but it fixes the bad textures in Spikeout. 2016-11-22 20:30:10 +00:00
Ian Curtis 84ae8f035c Skip processing the mipmap section of memory. The real3d doesn't create mipmaps down to 1x1 that is needed to do mipmapping properly on modern hardware anyway. 2016-11-21 09:04:56 +00:00

Ian Curtis 483ba2f398 Fix the shading in scud. When lighting is disabled the fixed shading intensities appear to be offset values added to the colour value. 2016-11-11 17:50:27 +00:00

Ian Curtis c3581c9fe8 Support multiple microTextures, fixes crazy texturing in sega ski champ. I'm assuming microtextures are always located on the other memory bank to the base texture. This logic seems to work for all our games anyway. 2016-10-06 01:37:29 +00:00

Bart Trzynadlowski 2efe18b525 Added support for multiple value types in config nodes. 
Removed Ptr_t and ConstPtr_t from public interface, moved config tree builders into their own file, and made them pass by reference and value.
Exceptions can be thrown now on lookup failures.
Removed s_empty_node -- failed lookups in [] operator create a permanent "hidden" child.

Bart Trzynadlowski 9a49fefe12 Legacy engine: fixed texture offsets (VON2 was broken by last commit). Texture coordinates are wrapped within the bank first and then the bank can be swapped.

Ian Curtis 36074d9fd5 Y texture offsets are just 5 bits. Texture coordinate wrap around happens in the same texture sheet, not into the next one. Fixes various texturing bugs in sega rally. 2016-05-30 13:25:00 +00:00

Bart Trzynadlowski 0ebb8d5d47 Legacy engine: Added stencil buffering for layered models and shadows. Not as accurate as new engine because stencil buffering is applied per-model rather than per-polygon, so the entire model must consist of stencil-tested polygons. In practice, though, this seems to work fine. 2016-05-28 19:52:30 +00:00

Ian Curtis 828fd8ebb4 Fog start is apparently the fog value at the viewport (0,0,0) I guess like an ambient value. Default value is negative 2016-05-16 17:10:04 +00:00
Ian Curtis 9e279a0c1f Non luminous polygons seem to be effected by the lightModifier also. API seems to have no restriction in this regard, neither does the SDK. The ocean hunter requires this for some of the 2d stuff. Light modifier values only seem to exist between 0-16, which is strange for 5 bits of precision. Possibly top bit disables the effect and lower 4 bits are the value. This clearly differs from the SDK, but without this the values come out clearly wrong. 2016-05-16 10:49:00 +00:00

Bart Trzynadlowski 897b1acb21 Legacy renderer changes: 
- Updated shading model. Unfortunately, it is far from perfect but it seems to be the best I can do for now. Not really much of a difference from before except that the Scud Race castle is fixed at the expense of the Yosemite level in LA Machineguns being too bright.
- Added lots of notes in the shading code.
- Passing both specular coefficient and shininess to shader. This will probably break specular lighting for now until the shader is updated to use the shininess correctly.
- Color table address in polygon RAM is now obtained from culling nodes as they are traversed (found this in the Pro-1000 SDK).

Bart Trzynadlowski 846c9d0edd Reverted stencil mask change. This reintroduces the Scud Race 'ROLLING START' bug. Previous 'fix' did not work for Magical Truck Adventure anyway and also broke some games (Daytona 2 transmission and course select screen, ECA title screen). The stencil mask is not shifted by 16 pixels and I suspect that either there is some unknown trick to horizontal scrolling or that the behavior is affected by hidden raster timing registers hidden in the JTAG interface. 2016-05-08 21:17:02 +00:00
Bart Trzynadlowski a9095e6c8e Added a register read handler for tilegen (although nothing seems to benefit from it) 2016-05-08 20:30:45 +00:00

Bart Trzynadlowski 5d048958b9 Rewrote 2D renderer and fixed 2D layer priorities, stencil mask clipping (Scud Race 'ROLLING START'), and cleaned up code. Unfortunately, the new code is about 50% slower, mostly due to the need to perform stencil clipping after scrolling. 2016-05-07 21:54:03 +00:00

Nik Henson 8835d6fe36 Some updates to Supermodel made at beginning of the year but only now got around to checking in (better late than never...): 
- hooked up the remaining controls in Supermodel (except for Magical Truck Adventure which does not work at all yet).  The new controls are:
  * InputAnalogJoyTrigger2 and InputAnalogJoyEvent2 for the additional second trigger and event buttons that were missing from Star Wars Trilogy,
  * InputRearBrake and InputMusicSelect for the rear brake and music selection buttons that were missing from Harley Davidson,
  * InputAnalogGunXXX, InputAnalogTriggerXXX, InputAnalogGunXXX2 and InputAnalogTriggerXXX2 for the analogue guns of Ocean Hunter and LA Machineguns (NOTE: these controls must be calibrated in the games' service menus otherwise they will not work properly.  Also, the alignment of the gun cursor does not line up very well with the mouse position at the moment, but at least the games are a bit more playable now, although still with numerous graphical glitches...)
  * InputSkiXXX for the controls of Ski Champ, making the game playable now.
- hooked up existing InputViewChange control to Harley Davidson's view change button
- improved the handling of InputGearShiftUp/Down inputs so that they work better with the driving games.  With Dirt Devils, ECA, Harley and LeMans this means they map directly to the game's own shift up/down controls, while with the 4-speed games such as Daytona 2, Scud Racer and Sega Rally 2, they simulate the user shifting up and down through the gears
- added defaults for the new controls to Supermodel.ini
- other small code tweaks:
  * fix small bug with handling of pos/neg inputs mapping to a control with inverted range (0XFF to 0x00) - this was needed to get Ski Champ's X-axis to work properly
  * removed Wait method from InputSystem and added to CThread as CThread::Sleep instead
  * added FrameTimings struct to hold all frame timings in a single place
No networking code yet as just haven't had a chance to work on it since initial progress at the beginning of the year - am *hoping* might have some time to pick it up again over Christmas...

Bart Trzynadlowski b017b24b1f Changed output "Pause" to "pause", as it is spelled in MAME, for MAMEHooker. 2012-09-06 05:38:35 +00:00
Nik Henson 08d347ccc7 Small tweak to get to compile under GCC (Unix/MacOS) 2012-07-24 20:37:40 +00:00
Nik Henson a3c15e8208 Slight tweak to changes made to sound board synchronisation code in previous commit. The previous change was necessary to ensure no deadlock when waiting for sound board thread to exit but it introduced unwanted buffer overruns (with the end result being that the sound was often speeded up) so have added an extra check in WakeSoundBoardThread to prevent this. 2012-07-24 20:18:30 +00:00
Nik Henson 108ac64de8 - CModel3::StopThreads was rather gracelessly killing threads while they were waiting on their semaphores, which works okay Windows but not on Mac OS-X where it was preventing Supermodel from exiting properly. Hence, have instead altered StopThreads to signal to threads that they should exit and wait until until they have all done so. This is much better and is what I should have done the first time around had I not been so lazy :-)! 
- Also fixed a small race condition in WakeSoundBoardThread.  Previously if it happened to be called just before the sound board thread had finished processing a frame's worth of audio but before it had got around to waiting on the sync condition variable then the wake notification would be lost.
 2012-07-23 20:35:10 +00:00
Bart Trzynadlowski f1e93bcd8f - Fixed Win32 GCC Makefile. 
- Reverted Nik's polygon palette index change in Models.cpp. Subtracting 1 was breaking Scud Race.
- Added an explicit typecast in Inputs.cpp, which GCC requires for some reason.
 2012-07-16 02:27:55 +00:00
Nik Henson 183dca563d Committing various small updates that have been hanging around in my source tree for a while now: 
- Added 'crosshairs' command line and config option.
- Added 'vsync' command line and config option (so far only tested on NVidia cards on Windows 7 - other graphics drivers, O/Ss or driver settings may simply chose to ignore this).
- Added fullscreen toggle within game using Alt+Enter key combination.
- Added framework for lamp outputs and 'outputs' command line and config option.  So far only the lamps for driving games are hooked up in the emulator (others to be added later).
- Added an initial outputs implementation for Windows that sends MAMEHooker compatible messages (-outputs=win to enable)
- Fixed fps calculation in Main.cpp that was producing incorrect results and so giving the impression that frame throttling wasn't working properly when in fact it was.
- Fixed palette indexed colours as the index was always off by one, causing incorrect colours in various games, eg drivers' suits and flashing Start sign in Daytona 2.
- Altered caching of models so that models with palette indexed colours use the dynamic cache rather than the static one.  This is so that changes in palette indexed colours appear on screen, eg the flashing Start sign on the advanced course of Daytona 2 (although currently the START message itself is not visible due to other problems with texture decoding).
- Fixed small bug in TileGen.cpp which meant both palettes were being completely recomputed pretty much with every frame.  This was a significant performance hit, particularly as palette recomputation is currently being done in SyncSnapshots (it should be moved out of here at some point, although for now it's no big deal).
- Made sure all OpenGL objects and resources are deleted in Render2D/3D destructors, in particular the deleting of the VBO buffer in DestroyModelCache.
- Made sure that GLSL uniforms are always checked to see if they are bound before using them in order to stop unecessary (but harmless) GL errors.
- Altered the default texture sheet handling to use a single large GL texture holding multiple Model3 texture sheets rather than multiple GL textures as before (if required, the old behaviour can still be selected with the mulisheet fragment shader).  I believe this fixes the disappearing crosshairs/corrupt GL state problem which the multisheet fragment shader seemed to be triggering somehow.
- Fixed a bug in debugger which meant memory watches were not triggering properly

Bart Trzynadlowski 772c94d122 - Committing Nik's timing changes: the PowerPC's DEC and TBR now count at the correct rate and time is accurately maintained between calls to the emulator. A VBlank bit was identified in the Real3D status register space and is now timed. Unfortunately, there are still some problems and not all games are perfect, but FV2, VS2, and others are working much better or perfectly. 
- Added a new dump of Scud Race Plus (scudp1). Strangely, this one uses an MPC106 instead of the MPC105 used by every other Step 1.5 game...

John Peterson 3963a7a53c Applied a series of patches by John Peterson: 
- Fixed a printf statement in ConsoleDebugger.cpp.
- Fixed memory watches not breaking in CPUDebug.h.
- Added some helpful batch files to the VS2008 directory.
- Added support for automatic loading of parent ROM sets.

Bart Trzynadlowski 93b71c8429 Applied Nik's fix for cyclical scene graphs. Improves Harley Davidson, Ski Champ, Emergency Call Ambulance, and Ocean Hunter. 2012-03-31 19:41:55 +00:00
Bart Trzynadlowski 1bce444668 Brought in the near clipping plane for Step 1.5+. Objects close to camera are no longer cut-off (e.g., driver arms and steering wheels in cockpit views). Note: This change should probably be applied to Step 1.0 as well in the future. For now, I am leaving the old distance because Step 1.0 coordinates need closer investigation. Bringing in the near clipping plane extends the view frustum depth and will worsen Z-buffer accuracy. Be on the lookout for Z-fighting that did not previously exist. 2012-02-28 04:34:32 +00:00
Nik Henson f9c3b9b5f8 DirectInputSystem's initial state wasn't being initialized properly, which would sometimes result in invalid input values until keyboard or mouse was successfully acquired 2012-02-27 20:32:15 +00:00
Bart Trzynadlowski 69610ef8dd Added a clear() method to VBORef and removed unsafe memset() clear. 2012-02-25 06:36:04 +00:00
Nik Henson 3b41239cfb This update fixes (hopefully) the last of the texture upload lags that were affecting some games, in particular Daytona 2 and Spikeout. 
To achieve this UploadTextures no longer clears the model cache when called.  Instead the cache is kept in-tact (which should help improve cache hits) and all textures referenced by models being rendered are (re-)decoded with every frame.
To help with tracking all the unique texture references contained in a model a new class TextureRefs has been added.

Bart Trzynadlowski aba801ebb4 Byte swapped sample ROMs. This should fix the audio distortion that many users noticed. The differences are particularly noticeable in Scud Race and Daytona 2. 2012-02-23 03:08:57 +00:00
Bart Trzynadlowski 16e4fcab06 Forgot to update to-do list in previous revision. Added a comment to mark CRender2D::WriteVRAM() as deprecated. 2012-02-23 00:12:46 +00:00
Bart Trzynadlowski fcf1d955a9 Previous "optimization" contained a mistake and made things worse. Removed unnecessary clear of the bottom layer buffer. Now, if there is no bottom layer, it will not be displayed at all and glClear(GL_COLOR_BUFFER_BIT) is used instead. 2012-02-22 01:34:42 +00:00
Bart Trzynadlowski c085be59af Further optimization/simplification of the 2D renderer's main loop. 2012-02-20 04:09:11 +00:00
Bart Trzynadlowski 453df4f5f5 - Finished cleaning up and optimizing the 2D renderer. 
- Fixed up color offset register support for new 2D rendering system. Now maintains 2 computed palettes for layers A/A' and B/B'.
- Fixed a minor bug in InitPalette(); VRAM was not being typecast properly.
- Fixed specular lighting bug that occurred on some OpenGL drivers because integers were not being interpreted as floats in the vertex shader.
- Began to update copyright date in some files.
- Graphics modules now use the C++-style names for C standard library headers (e.g., stdio.h -> cstdio) consistent with the rest of Supermodel.

Bart Trzynadlowski 0257f1f9e8 Contour processing (discarding of pixels when alpha==0) enabled for A4L4 texture formats. Improves smoke and fire in Daytona 2. 2012-02-17 07:45:50 +00:00
Bart Trzynadlowski 5709010cb2 Default SCSP balance set to 0. Was erroneously set at +50%. 2012-02-14 09:13:36 +00:00
Bart Trzynadlowski 79d24d403f - NOTE: In this revision (possibly earlier), I've started to notice some intermittent geometry glitches in Spikeout and slowdown while playing certain characters. 
- Added multi-texture fragment shader to repo.
- Added a multiTexture option (enabled by default) to use multi-texturing to decode textures.
- Added some comments regarding timing to the PowerPC execution loop.

Nik Henson 30130f2bd5 Updated fragment shaders' floating point comparisons and also some knock-on changes from SVN revision 246. 2012-02-13 23:51:32 +00:00
Nik Henson 8a4ea64994 Added OSD/Video.h to provide OSD-dependent video functionality. The static functions in here get called by Model3.cpp from within the render thread so that any OSD related rendering can also be run in parallel for a further speed increase. 
Updated OSD/SDL/Main.cpp to provide the SDL implementations of the functions in OSD/Video.h.
 2012-02-13 23:37:48 +00:00
Nik Henson 84eb017744 Added support for multiple texture sheets (with up to one per Model 3 texture format) as a rather brute-force way to handle overlapping texture formats in the current 3D engine. This fixes some corrupt textures in Daytona 2 and Virtua Striker 2 (and possibly other games) and also offers a small speed increase when some scenes load multiple overlapping textures. 
This feature only enables itself when a compatible shader script is loaded.  Since none have been checked in yet this means it is currently disabled.

Bart Trzynadlowski 35a47bc7e3 Added command line options to force windowed mode and to control GPU multi-threading. 2012-02-11 16:40:09 +00:00
Bart Trzynadlowski 1b8740165c Added a wide screen hack that can be enabled with the -'wide-screen' argument or WideScreen in the config file. 2012-02-10 19:53:51 +00:00
Bart Trzynadlowski 40a51287df Tweaked help text slightly. 2012-02-09 17:15:15 +00:00
Bart Trzynadlowski 09f9bd81fd Fixed left/right stereo channels -- they were reversed by default. 2012-02-09 17:12:13 +00:00
