Gl.LoadIdentity (gb.opengl)

Replace the current matrix with the identity matrix.

Description

Gl.LoadIdentity replaces the current matrix with the identity matrix. It is semantically equivalent to calling Gl.LoadMatrix 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 Gl.LoadIdentity is executed between the execution of Gl.Begin and the corresponding execution of Gl.End.
