glActiveTextureARB(3)

NAME

       glActiveTextureARB - select active texture unit

C SPECIFICATION

       void glActiveTextureARB( 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  implementa-
                tion-dependent value.  The initial value is GL_TEXTURE0_ARB.

DESCRIPTION

       glActiveTextureARB  selects which texture unit subsequent texture state
       calls will affect.  The number of texture units an implementation  sup-
       ports is implementation dependent, but must be at least 2.

       Vertex  arrays  are client-side GL resources, which are selected by the
       glClientActiveTextureARB routine.

NOTES

       glActiveTextureARB is only supported if GL_ARB_multitexture is included
       in  the  string  returned  by glGetString when called with the argument
       GL_EXTENSIONS.

ERRORS

       GL_INVALID_ENUM   is   generated   if   texture   is   not    one    of
       GL_TEXTURE$i$_ARB,
       where 0 <= $ i $ < GL_MAX_TEXTURE_UNITS_ARB.
