Info

Built-in functions• dot() - takes the dot product of two vectors• sin, cos, pow, etc. - similar to math.h in C– Angles are in radians• ftransform() - perform fixed transform• reflect() - reflect a vector about another vector• Many more! See GLSL reference
Communication between shaders• What if shader need more informationthan given by the built-ins?– Special keywords…• Vertex -> fragment: varying• CPU -> both (per render): uniform• CPU -> both (per vertex): attribute• CPU -> both (large data): use a texture– We'll see this next week…
