Bart Trzynadlowski 1a908dd414 Legacy engine: expanded color index to 12 bits from 11. Does this affect any games? 2016-05-28 20:50:05 +00:00
Bart Trzynadlowski 2ef5203839 Forgot to describe one polygon header field in Model.cpp 2016-05-28 20:40:45 +00:00
Bart Trzynadlowski e4a5c341dd Updated polygon header descriptions 2016-05-28 20:33:10 +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 89c987fae1 basic spotlight code 2016-05-26 00:08:12 +00:00
Bart Trzynadlowski a0910f96fb Fixed fog in legacy 3D engine. Now computed same as new engine, with 4-bit light modifier and corrected fog mixing in shaders. 2016-05-25 04:00:02 +00:00
Bart Trzynadlowski 6dc35f9563 Updated legacy engine vertex shader to use specular shininess and coefficient along with old equation. Still not correct (too strong compared to the old method). 2016-05-25 03:10:36 +00:00
Ian Curtis fd3eb49369 support 4 bit textures 2016-05-21 15:50:54 +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).

Ian Curtis 6d1aa4d527 fix compilation 2016-05-03 18:38:06 +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
Bart Trzynadlowski 57d5bc8367 Legacy engine: preliminary per-vertex fixed shading. Only limited testing with LA Machineguns (appears to work), Sega Rally 2 (appears okay), and Scud Race (fixes expert course bridge but not other mis-colored polygons). 2016-04-29 03:56:06 +00:00
Bart Trzynadlowski 34e8f00382 Legacy engine: extracting fixed shading component (but still can't use it because unsure of how to activate) 2016-04-28 13:18:15 +00:00
Bart Trzynadlowski c0ec610e99 Polygon header bit analysis code (need to #define DEBUG and use -gfx-state option) 2016-04-27 04:09:50 +00:00
Bart Trzynadlowski 3682ab7300 Updated polygon header description with double-sided bit (forgot it in last update!) 2016-04-26 23:06:40 +00:00
Bart Trzynadlowski 85a77bb016 Added an updated description of the polygon header to the top of Legacy3D/Models.cpp 2016-04-26 23:04:11 +00:00
Bart Trzynadlowski b730fc466c Legacy engine: vertex normals are standalone and do not need to be added to polygon normal 2016-04-26 00:12:02 +00:00
Bart Trzynadlowski 6d9426759b Fixed texture enable bit (fixes Star Wars light sabers and Sega Rally 2 cones) and added a hack for (and more comments about) color modulation. Scud Race, Sega Rally 2, LA Machineguns, etc. look correct now, but Fighting Vipers 2 shadows are no longer dark enough. Other bugs may exist. 2016-04-04 03:50:24 +00:00
Bart Trzynadlowski 3c8352f4ca Added a comment: observation of Star Wars and Scud Race color modulation issues. 2016-04-03 04:09:06 +00:00

Ian Curtis 93f6b01e0b Update project to vs 2013. Clean compile warnings 2016-03-22 12:30:23 +00:00
Bart Trzynadlowski 3627213577 Fixed compiler warnings, whitespace, and moved local variable declarations to site of assignment 2016-03-22 03:43:31 +00:00
Bart Trzynadlowski 34301e97e1 Adding new 3D engine by Ian Curtis. Old engine moved to Graphics/Legacy3D/. 2016-03-21 04:10:14 +00:00
