Learn OpenGL. Lesson 6.3 - IBL. Diffuse irradiation

Learn OpenGL. Lesson 6.3 - IBL. Diffuse irradiation Lighting based on the image or IBL 3r31207. (3-3331206. Image Based Lighting 3-3331207.) - is a category of lighting methods based not on analytical light sources (discussed in 3-331250. The previous lesson 3r-31297.), But considering the whole environment of the illuminated objects as one continuous light source. In general, the technical basis of such methods lies in processing a cubic environment map (prepared in the real world or created on the basis of a three-dimensional scene) so that the data stored in the map can be directly used in lighting calculations: virtually every texel of a cubic map is considered ...
