In learning to matcap recently have a little question, why the information such as the light projected onto a sphere (or half spherical/circle)? Why not cubemap?
If the said spherical light, cubemap more mature, isn't it? Matcap advantage where and why matcap with one and a half sphere of light information to store it?
Is really not understand, also please great god can tell!!!!!!
Thank you very much!!!!!!!!!!!!!!!!!!!!!!!

Everyone a great god, o top, give advice or comments!!!!!!!!!!

My understanding is cube map takes six texture maps and matcap only need a
Don't have too many small cost...
Finally realize the lighting effects between actually thinking about
What is primarily a mapping object, depends on your specific view environment

Two is not the same thing, the cubemap simulation is the environment light. Matcap simulation calculation of the surface of the material after color is, and then save up. You can imagine is an absolute smooth balls, you go to watch the ball, got is matcap. The effect of preserved after other objects directly read to go, and use it every time you don't have to recalculate.
