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 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 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 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 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 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 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 b57ba51e44 Removed unused (and non-functional) 'stack machine' scene graph traversal. 2012-01-18 08:12:23 +00:00
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 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.

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.

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.

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.

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).

Bart Trzynadlowski 783446fca2 Fixing import mistake: moving source code to trunk/Src. 2011-04-24 01:19:40 +00:00
Renamed from Graphics/Render3D.cpp (Browse further)
