Using Cube Maps in OpenGL

Very easy to use NVIDIA extension



• New texture target: GL_TEXTURE_CUBE_MAP_NV
  • Used for manipulating cube map as a whole
• Six cube map “face” targets
  • Used for manipulating particular cube map faces
  • GL_TEXTURE_CUBE_MAP_dir_axis _NV
  • dir is { POSITIVE, NEGATIVE }
  • axis is { X, Y, Z }
  • Use 2D texture image API (glTexImage2D, etc)
