# 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.
