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

$\left(\begin{array}{cccc}1& 0& 0& 0\\ 0& 1& 0& 0\\ 0& 0& 1& 0\\ 0& 0& 0& 1\end{array}\right)$

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.
