Christoph Oelckers	7793bbbcc9	Further cleanup of lighting code. ... - remove thing color from lighting calculations. - implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner. - fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation. - added functions for isolated calculation of sprites' dynlight color.	2014-05-11 17:56:38 +02:00
Christoph Oelckers	f7404d20fb	- add vertex buffer based drawing for all walls and flats.	2014-05-11 01:23:27 +02:00
Christoph Oelckers	b09405a8bd	- changed rendering of glowing walls so that it doesn't require an additional vertex attribute, just pass the floor and ceiling planes as uniforms.	2014-05-10 17:09:43 +02:00
Christoph Oelckers	a73d1b792c	- fixed: Assignment of GetLightLevel to GLWall::lightlevel must be clamped. This was done incorrectly in the last SVN version which clamped the result of GetLightLevel, causing problems elsewhere.	2013-06-23 10:17:58 +02:00
Christoph Oelckers	399d0974ab	- added GL render as of SVN revision 1600.	2013-06-23 09:49:34 +02:00
