GLACTIVETEXTUREARB(3G)                                                                GLACTIVETEXTUREARB(3G)



NAME
       glActiveTextureARB - select active texture unit


C SPECIFICATION
       void glActiveTextureARB( GLenum texture )


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_TEXTUREi_ARB, where 0 <= i  <
                GL_MAX_TEXTURE_UNITS_ARB,  which  is an implementation-dependent value.  The intial value is
                GL_TEXTURE0_ARB.

DESCRIPTION
       glActiveTextureARB 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 2.

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

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_TEXTUREi_ARB,
       where 0 <=i < GL_MAX_TEXTURE_UNITS_ARB.
