glActiveTexture: select active texture unit
Function Definition
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 80. 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.
Description
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 80.
Errors
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).
Associated Gets
glGet with argument GL_ACTIVE_TEXTURE, or GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
