glLoadIdentity

Name

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.
