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().
