glClientActiveTextureARB
- select active texture unit
C SPECIFICATION
void glClientActiveTextureARB(
GLenum texture )
delim $$
PARAMETERS
texture
Specifies which texture unit to make active. The number
of texture units is implementation dependent, but must be at least
two. texture must be one of GL_TEXTURE$i$_ARB
where 0 < $ i $ < GL_MAX_TEXTURE_UNITS_ARB, which is an
implementation-dependent value. The initial value is
GL_TEXTURE0_ARB.
DESCRIPTION
glClientActiveTextureARB selects the vertex array client state parameters to be modified by
glTexCoordPointer, and enabled or disabled with
glEnableClientState or glDisableClientState, respectively,
when called with a parameter of GL_TEXTURE_COORD_ARRAY.
NOTES
glClientActiveTextureARB is supported only if GL_ARB_multitexture is included in the
string returned by glGetString when called with the argument
GL_EXTENSIONS.
glClientActiveTextureARB sets GL_CLIENT_ACTIVE_TEXTURE_ARB to the active texture unit.
ERRORS
GL_INVALID_ENUM is generated if texture is not one of
GL_TEXTURE$i$_ARB, where
0 < $ i $ < GL_MAX_TEXTURE_UNITS_ARB.
