glLoadIdentity3x

C specification

void glLoadIdentity( void )

Overview

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

left ( down 20 { ~ matrix {
ccol { 1 above 0 above 0 above 0~ }
ccol { 0 above 1 above 0 above 0~ }
ccol { 0 above 0 above 1 above 0~ }
ccol { 0 above 0 above 0 above 1 } } } ~~ 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.
