Ian Curtis c2b1db11f8 Cull geometry based on the culling distances in the nodes. Should give some sort of speedup on lower end pcs where the CPU is predominantly the bottle neck. 2016-06-16 20:05:29 +00:00
Bart Trzynadlowski f31f06b42e Fix compilation when SUPERMODEL_DEBUGGER enabled 2016-06-13 00:53:39 +00:00
Ian Curtis d799c63b1a cache bound texture 2016-06-10 11:29:20 +00:00
Ian Curtis 48a79a8f14 cleaning 2016-06-10 10:18:47 +00:00
Bart Trzynadlowski b0911afd1f Added drive board and lamp raw outputs (submitted by SailorSat) 2016-06-07 01:51:16 +00:00
Ian Curtis 8440bc7f03 support negative exponent 2016-06-03 09:33:46 +00:00
Ian Curtis 5081ee99dc Add code to convert the 16bit float format used by the hardware back into float 754 format. 16bit floats are used for the culling radiuses in the nodes. 2016-06-03 00:01:34 +00:00
Bart Trzynadlowski 6dc5845d47 Added -vsync and -no-vsync option descriptions to command line help 2016-06-02 23:51:43 +00:00
Ian Curtis 9bc1fbf0cb remove dead code 2016-06-02 21:26:50 +00:00
Bart Trzynadlowski 968652bcfb Added a Split() function to Util::Format. 2016-06-02 03:14:46 +00:00
Bart Trzynadlowski d1330d310c XInput fix: search for all three possible XInput DLLs (xinput1_4.dll, xinput1_3.dll, and xinput9_1_0.dll). I have not tested 32-bit builds. 2016-06-02 00:13:42 +00:00
Ian Curtis ff8e9d6aad Check for overflow. Fixes some fade effects 2016-05-30 23:10:56 +00:00
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. This also allows the full range of texture coordinate bits to be used as specified in the Pro-1000 SDK. 2016-05-30 19:18:11 +00:00
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 d1f49675b1 Legacy engine: Culling node texture Y offset is only 5 bits (fixes Sega Rally 2 initials decal) 2016-05-29 20:49:28 +00:00
Bart Trzynadlowski 2ee0d9018e New engine: modf -> std::modf (fixes compilation on gcc) 2016-05-28 20:54:25 +00:00
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 5c1a240565 New engine: expanded color indices to 12 bits from 11. Added PolygonHeader::ColorIndex and SensorColorIndex methods. 2016-05-28 20:49:10 +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 ce03c13847 Optimise non smooth texture repeat to only effect texture boundaries, rather than poly boundaries. Fixes a few ugly artefacts 2016-05-28 13:21:35 +00:00
Ian Curtis 661f19be19 fix transparency values, values are from 0-32, not 0-16 where the top bit disables 2016-05-27 22:20:57 +00:00
Ian Curtis 2086b1c9af Stencil layered polys, fixes shadow z fighting in some of the games. Other games maybe using stipple alpha (yuck), not sure yet. 2016-05-27 19:30:40 +00:00
Ian Curtis 8979246642 remove bad rom patches 2016-05-26 16:21:42 +00:00
Ian Curtis 3f9936d664 don't clamp after spot light code, looks much closer to h/w 2016-05-26 09:06:09 +00:00
Bart Trzynadlowski 8ba8d7290e Hooked up Sega Bass Fishing / Get Bass controls 2016-05-26 04:13:22 +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 c5ce2b9679 fix alpha testing for texture format 7 2016-05-22 19:17:15 +00:00

Ian Curtis 7e3c097a31 remove debug code 2016-05-16 17:26:53 +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
Ian Curtis 62eafacfc3 adjust (hopefully correct) fog equation 2016-05-16 10:44:16 +00:00
Ian Curtis bc08276d60 preliminary specular 2016-05-15 16:24:49 +00:00
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).
