GLMATRIXMODE()                                                  GLMATRIXMODE()

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.

DESCRIPTION
       glMatrixMode sets the current matrix mode.  mode can assume one of
       three 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.

       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.
