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 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
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 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 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 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.
2012-02-13 21:54:26 +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 6814ef1ed8 Added preliminary specular lighting to shaders. The "no spotlight" shader has not yet been updated. 2012-02-06 02:54:43 +00:00
Bart Trzynadlowski 0fcb9686f9 Documented the tile generator. 2012-01-27 22:27:38 +00:00
Bart Trzynadlowski 8a8609f383 - Added specular highlight support to the 3D engine. A shininess parameter is now be passed to the shaders. Does not work correctly and I will save the shaders themselves for a future commit.
- Added support for layer priorities. Highly unoptimal! This absolutely needs to be polished up before any release (and properly documented). For now, priorities in the popular games seem to be fixed but not all possible priority settings have been figured out yet.

Bart Trzynadlowski 3315fb463b Small correction to lighting model in shaders. Light intensity is no longer clipped. 2012-01-22 01:05:59 +00:00
Bart Trzynadlowski b57ba51e44 Removed unused (and non-functional) 'stack machine' scene graph traversal. 2012-01-18 08:12:23 +00:00
Nik Henson d1d5175548 New multi-threaded rendering changes that parallelise graphics rendering and PPC execution in order to increase performance on multi-core machines.
New gpuMultiThreaded config option to enable/disable multi-threaded rendering (enabled by default, disabling it reverts to previous behaviour).
Other rendering optimisations:
 - texture uploads now only affect appropriate region in the texture sheet, rather than uploading the whole sheet each time
 - performance of clearing the model caches has been improved
New Alt+O key input added to toggle outputting of frame timings for debugging purposes.

Bart Trzynadlowski bdf11c765f Preliminary backface culling fix. Matrices which effectively change the polygon winding without changing the Z component of the polygon normal are tested for when appending items to the display list. If necessary, the polygon winding is changed on the fly to ensure visibility is correct. This code desperately needs to be optimized. Note: Not yet thoroughly tested. 2011-12-26 06:10:55 +00:00
Bart Trzynadlowski 7f97346fc9 - Tweaked some error messages and comments. Hopefully, this is the last update for v0.2a's code.
- Documentation updates.
2011-09-24 01:49:48 +00:00
Bart Trzynadlowski 2f5bf43bda Updated copyright information and added headers to all remaining files except debugger. 2011-09-14 19:08:43 +00:00
Bart Trzynadlowski 11d1d61bc2 - Removed BOOL and replaced it with native C++ type, bool.
- Removed TRUE and FALSE, changed to 'true' and 'false' keywords.
2011-09-08 06:34:18 +00:00
Bart Trzynadlowski d318efe58c - Program settings are now managed by the CConfig class.
- Moved Logger.h to OSD/, cleaned up comments.
- Command line and config file parsing have been rewritten.
- Began replacing C standard library headers with C++ versions (eg. stdio.h -> cstdio). I think I got most of them, but not all.
2011-08-19 20:43:07 +00:00
Bart Trzynadlowski fce3c7ad7c - skichamp now works, but controls are not hooked up and seems to overload the display lists like many non-working Step 2.x games do. To bypass the drive board error, enter the test menu and exit again. It will reboot and run.
- Added some notes on the cause of the "NO DAUGHTER BOARD DETECTED" error in Real3D.cpp.
- Removed some debug code from texture uploader.
2011-08-02 03:33:40 +00:00
Bart Trzynadlowski ddd6fa92ef - Improved 68K interface. Now supports context switching.
- CSoundBoard is not derived from CBus.
- Optimized sound board memory handlers (now using switch statements).
- Added DSB emulation (based on R. Belmont's M1 source code).
- Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily.
- General cleanup here and there, removed unused Render.h file.
2011-07-31 02:37:31 +00:00
Bart Trzynadlowski 79e8172340 - Textures are no longer decoded for un-textured polygons (not sure if this fixes anything yet). 2011-07-22 19:01:45 +00:00
Bart Trzynadlowski d2ecec7997 - Textures are no longer decoded for un-textured polygons (not sure if this fixes anything yet). 2011-07-22 18:56:35 +00:00
Bart Trzynadlowski a033058deb - Texture offsets: models are now decoded for each individual texture offset state and texture coordinates are adjusted while generating the vertex data.
- Model LUT now capable of differentiating between texture offset states (linked list of different texture offsets for each model address).
- Removed texOffset uniform attribute from vertex shader -- no longer needed.
2011-07-21 08:12:16 +00:00
Bart Trzynadlowski a90075830c Texture offsets. 2011-07-06 05:05:38 +00:00
Bart Trzynadlowski cd2621b2ce Added texture offsets. Vertex shader has been updated in Shaders/Vertex.glsl.
Added palette initialization to 2D renderer. Fixes 2D graphics corruption when loading states (most visible in Scud Race).
2011-07-04 20:53:37 +00:00
Bart Trzynadlowski 783446fca2 Fixing import mistake: moving source code to trunk/Src. 2011-04-24 01:19:40 +00:00
