GLMATRIXMODE(3G)                                                                            GLMATRIXMODE(3G)



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
