glLoadIdentity : PyOpenGL 3.0.2 GL Man Pages

replace the current matrix with the identity matrix

Signature

glLoadIdentity( ( void ) )-> void

glLoadIdentity( )

Description

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

(\begin{matrix} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{matrix})

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 .

Associated Gets

glGet with argument GL_MATRIX_MODE

glGet with argument GL_COLOR_MATRIX

glGet with argument GL_MODELVIEW_MATRIX

glGet with argument GL_PROJECTION_MATRIX

glGet with argument GL_TEXTURE_MATRIX
