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 op‐
       erations, 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
