void glLoadIdentity( void )

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

(down20 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.

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