GLLOADIDENTITY(3G)

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().

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
