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
32. texture
must be one of
GL_TEXTURE
i,
where i ranges from zero to the
value of
GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS
minus one. 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 32.
GL_INVALID_ENUM
is generated if texture
is not one of
GL_TEXTURE
i, where
i ranges from zero to the value of
GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS
minus
one.
glGet with argument GL_ACTIVE_TEXTURE
, or GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS
.
