Robert Beckebans	277964f074	Because I can :) ... - Implemented soft shadows using PCF hardware shadow mapping The implementation uses sampler2DArrayShadow and PCF which usually requires Direct3D 10.1 however it is in the OpenGL 3.2 core so it should be widely supported. All 3 light types are supported which means parallel lights (sun) use scene independent cascaded shadow mapping. The implementation is very fast with single taps (400 fps average per scene on a GTX 660 ti OC) however I defaulted it to 16 taps so the shadows look really good which should you give stable 100 fps on todays hardware. The shadow filtering algorithm is based on Carmack's research which was released in the original Doom 3 GPL release draw_exp.cpp. - Changed interaction shaders to use Half-Lambert lighting like in HL2 to make the game less dark - Fixed some of the renderer debugging/development tools like r_showTris	2014-05-10 14:40:01 +02:00
