*
|
|
* 24 98.10.03 11:11p Mmouni
|
|
* Put self moding code in code segment "SelfMod".
|
|
*
|
|
* 23 10/01/98 12:36a Asouth
|
|
* Rearranged includes to ensure proper config
|
|

|
* 22 8/27/98 9:13p Asouth
|
|
* fixed data type explicitly scoped
|
|
*

* 21 98.01.22 3:15p Mmouni
|
|
* Changed bump-map depth conditional compilation.
|
|
*
|
|
* 20 1/19/98 7:34p Pkeet
|
|
* Added support for 16 bit bumpmaps.
|
|
*
|
|
* 19 97.12.01 4:25p Mmouni
|
|
* P6 build now includes its own version of ScanlineAsmMacros.
|
|
*
|
|
* 18 11/16/97 3:56a Rwycko
|
|
* Now includes P6 version of water and terrain primitives.
|
|
*
|
|
* 17 97.11.11 9:51p Mmouni
|
|
* Now includes AMDK6 version of DrawSubTriangleTerrain and DrawSubTriangleWater.
|
|
*
|
|
* 16 97/11/10 11:26a Pkeet
|
|
* Added a water version of 'DrawSubTriangle.'

|
|
*
|
|
* 14 97.10.27 1:27p Mmouni
|
|
* Made changes to support the K6-3D.
|
|
*
|
|
* 13 97/10/23 10:56a Pkeet
|
|
* Added a K6 3D switch that uses the current pentium subtriangle.
|
|
*
|
|
* 12 97.10.15 7:36p Mmouni
|
|
* Now include DrawSubTriangle.hpp before DrawTriangle.hpp.
|

* 10 97/09/24 12:29 Speter
|
|
* Turned off the bloody warning.
|
|
*
|
|
* 9 9/15/97 1:58p Mmouni
|
|
* Added pvBaseOfLine, d_temp_a, and d_temp_b to statics.
|
|
*
|
|
* 8 8/28/97 4:07p Agrant
|
|
* Source Safe Restored to Tuesday, August 26, 1997

* 6 8/17/97 12:23a Rwyatt
|
|
* Added new includes for alpha primitive and the associated globals.
|
|
*
|

* 5 8/15/97 12:47a Rwyatt
|
|
* New includes for terrain primitives
|
|
*
|
|
* 4 97/07/16 16:01 Speter
|
|
* Reinstated VER_ASM switch for primitives. Now this file includes all DrawSubTriangle
|
|
* sub-modules; the processor gating is done only here.
