Web8 de jun. de 2013 · In GL 2.1, you have 2 ways to communicate information to shaders: uniforms and textures. If you attempt to use textures, you will have to not only use a float texture, you will have to fetch from that texture twice for every light. And if you compute all of the lights in one pass, that’s 200 texture fetches. notion diary studies
