light type in GLSL
Author
hi
1.how can i detect light type in GLSL ( for example gl_LightSource[0] is directional light or is point light);
2. how can i know wich light source is actived with gl_EnableFunction
for light type look at the position.w value. If it is 0 it is directional, else it has a 3D position not a infinity. look at this post about it (2nd post)
