NAME
       glMatrixMode - specify which matrix is the current matrix


C SPECIFICATION
       void glMatrixMode( GLenum mode )


PARAMETERS
       mode  Specifies which matrix stack is the target for subsequent matrix
	     operations.    Three   values   are   accepted:	GL_MODELVIEW,
	     GL_PROJECTION,   and   GL_TEXTURE.	   The	 initial   value   is
	     GL_MODELVIEW.

	     Additionally, if  the  GL_ARB_imaging  extension  is  supported,
	     GL_COLOR is also accepted.

DESCRIPTION
       glMatrixMode  sets  the	current	 matrix mode.  mode can assume one of
       four values:

       GL_MODELVIEW		Applies subsequent matrix operations  to  the
				modelview matrix stack.

       GL_PROJECTION		Applies	 subsequent  matrix operations to the
				projection matrix stack.

       GL_TEXTURE		Applies subsequent matrix operations  to  the
				texture matrix stack.

       GL_COLOR			Applies	 subsequent  matrix operations to the
				color matrix stack.

       To find out which matrix stack is currently the target of  all  matrix
       operations, call glGet with argument GL_MATRIX_MODE. The initial value
       is GL_MODELVIEW.

ERRORS
       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_OPERATION is generated if glMatrixMode is executed  between
       the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS
       glGet with argument GL_MATRIX_MODE
