Name[]
Cubemap - performs a texture lookup in a given CUBE sampler and, in some cases, a shadow comparison. May also use pre computed derivatives if those are provided.
Synopsis[]
vector4 texCUBE(vector3 Coord, vector1 Shadow, vector3 dx, vector3 dy); vector3 texCUBE(vector3 Coord, vector1 Shadow, vector3 dx, vector3 dy); vector1 texCUBE(vector3 Coord, vector1 Shadow, vector3 dx, vector3 dy);
Parameters[]
Coord
Coordinates to perform the lookup.
Shadow
It is used to perform a shadow comparison.
dx
Pre computed derivative along the x axis.
dy
Pre computed derivative along the y axis.
Description[]
Performs a texture lookup in a given CUBE sampler using coordinates Coord, may use derivatives dx and dy, also may perform shadow comparison through Shadow.
