GLLOADIDENTITY(3G)                                                                        GLLOADIDENTITY(3G)



NAME
       glLoadIdentity - replace the current matrix with the identity matrix


C SPECIFICATION
       void glLoadIdentity( void )


DESCRIPTION
       glLoadIdentity  replaces  the current matrix with the identity matrix.  It is semantically equivalent
       to calling glLoadMatrix with the identity matrix

                                                      1 0 0 0
                                                      0 1 0 0
                                                      0 0 1 0
                                                      0 0 0 1

       but in some cases it is more efficient.

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

ASSOCIATED GETS
       glGet with argument GL_MATRIX_MODE
       glGet with argument GL_COLOR_MATRIX
       glGet with argument GL_MODELVIEW_MATRIX
       glGet with argument GL_PROJECTION_MATRIX
       glGet with argument GL_TEXTURE_MATRIX
