Bart Trzynadlowski c9147bc93d - Removed a stale comment 2016-05-14 06:31:44 +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 147faf37c9 Added palette bit to list of bits to dump for analysis 2016-05-14 06:21:56 +00:00
Ian Curtis c4b5b185c6 Disable light modifier on fog, seems not to work .. values don't make sense. Maybe the model3 doesn't use these. 2016-05-13 19:26:10 +00:00
Ian Curtis c8f8cd1655 remove dead code 2016-05-13 08:40:53 +00:00

Bart Trzynadlowski ddf3d5213d FLT_MAX -> std::numeric_limits<float>::max() 2016-05-10 03:08:36 +00:00
Bart Trzynadlowski 8c082abab9 Added some IRQ-related code (commented out for now) from MAME findings. May incorporate in the future when investigating IRQs and timing again. 2016-05-10 03:08:03 +00:00
Ian Curtis 34c81eabee update header documentation 2016-05-09 16:53:12 +00:00
Ian Curtis 43add90d2f Fix bad texture seems 2016-05-09 16:26:34 +00:00
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 9249eaa29f Fixed logic for clearing bottom layer. Added new functions to 2D renderer interface. Avoid drawing top and bottom surfaces when no layers are present there. Added some comments to tile 2016-05-08 19:27:08 +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

Bart Trzynadlowski 48767b2267 Legacy engine: fixed per-vertex fixed shading to incorporate Ian's findings that the intensity value is signed and that fixed shading applies only when lighting is enabled 2016-04-30 16:23:25 +00:00
Ian Curtis 23a5839d46 Daytona seems to use 3 bits for texture transparency, will figure it out later but for now this works 2016-04-30 09:02:38 +00:00
