glActiveTexture — select active texture unit
void glActiveTexture(GLenum texture);
texture
Specifies which texture unit to make active. The number
of texture units is implementation dependent, but must be at least
48. texture must be one of
GL_TEXTUREi,
where
i ranges from 0 (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).
The initial value is GL_TEXTURE0.
glActiveTexture selects which texture unit subsequent texture state calls will
affect. The number of texture units an implementation supports is
implementation dependent, but must be at least 48.
GL_INVALID_ENUM is generated if texture is not one of
GL_TEXTUREi,
where i ranges from 0 to (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).
