|
* Classes for using, or not using, fogging in raster primitives.
|
|
*
|
|
* Notes:
|
|
*
|
|
* To Do:
|
|
* Find a faster way to fall through the 'SetFlatColour' member function if the
|
|
* 'CLineBumpMake' line primitive is being used.
|

* $Log:: /JP2_PC/Source/Lib/Renderer/Primitives/FogT.hpp $
|
|
*
|
|
* 14 98.09.19 12:39a Mmouni
|
|
* Added "forceinline" to many small inline functions.
|
|
* Inlined some functions for speed.
|
|
*
|
|
* 13 12/20/96 12:10p Mlange
|
|
* Moved fog source files to 'Renderer' directory.
|
|
*
|
|
* 12 12/15/96 2:44p Mlange
|
|
* CFogOn::u4Offset() now always returns 0.
|
|
*
|
|
* 11 10/14/96 10:06a Pkeet
|
|
* Made 'iDefaultFog' extern instead of static.
|
|
*
|
|
* 10 10/09/96 7:18p Pkeet
|
|
* Moved the 'iDefaultFog' global variable here.
|
|
*
|
|
* 9 10/03/96 3:15p Pkeet
|
|
* Removed the 'pvGetClutAddress' global function.
|
|
*
|
|
* 8 9/27/96 4:31p Pkeet
|
|
* Removed the 'SetFlatColour' member function.
|
|
*
|
|
* 7 96/09/25 15:40 Speter
|
|
* Changed pvAddFog to u4GetClutOffset.
|
|
*
|
|
* 6 9/24/96 2:52p Pkeet
|
|
* Added checks to ensure that the 'SetFlatColour' member function only sets a colour if a clut
|
|
* is present.
|
|
*
|
|
* 5 9/18/96 3:06p Pkeet
|
|
* Made the 'pvGetClutAddress' global function static. Disabled the 'SetFlatColour' member
|
|
* function for the 'CFogOff' class.
|
|
*
|
|
* 4 96/09/12 16:24 Speter
|
|
* Incorporated new TReflectVal usage.
|
|
*
|
|
* 3 96/09/09 18:30 Speter
|
|
* Made compatible with change of fIntensity to lvIntensity.
|
|
*
|
|
* 2 8/22/96 2:07p Pkeet
|
|
* Changed member functions to static member functions.
|
|
*
|
|
* 1 8/21/96 4:45p Pkeet
|
|
* Initial implementation.
