GLACTIVETEXTURE(3G)						    OpenGL 3.3						       GLACTIVETEXTURE(3G)

NAME
       glActiveTexture - select active texture unit

C SPECIFICATION
       void glActiveTexture(GLenum texture);

PARAMETERS
       texture
	   Specifies which texture unit to make active. The number of texture units is implementation dependent, but must be at least 48.  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 48.

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.
