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.

53f4cd0108 - added objectcolor uniform. This will be used to hold the thingcolor for shader based rendering. 2014-05-11 16:06:25 +02:00

09f4071436 Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code. 2014-05-11 13:27:51 +02:00

69af73d9b9 - alternative configuration using GLEW to get extension functions. This requires GL 2.0, though so it won't be promoted to the mainline for the time being.
- removed all pre GL 2.0 support.

12985cf635 - fixed: Particle drawing needs to apply the current fixed colormap to the particle's color. 2013-11-30 12:35:38 +01:00

62fd6c8e74 - fixed: light values read from 3D floor light lists for lighting sprites were not clamped to [0..255]. 2013-08-09 23:12:21 +02:00
