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


left ( down 20 { ~ matrix {
   ccol { 1 above 0 above 0 above 0~ }
   ccol { 0 above 1 above 0 above 0~ }
   ccol { 0 above 0 above 1 above 0~ }
   ccol { 0 above 0 above 0 above 1 } } } ~~ right )

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.
