glTranslate
glTranslated, glTranslatef: multiply the current matrix by a translation matrix.
C Specification
void glTranslated(
GLdouble x,
GLdouble y,
GLdouble z)
void glTranslatef(
GLfloat x,
GLfloat y,
GLfloat z)
Parameters
x, y, z Specify the x, y, and z coordinates of a translation vector.
Description
glTranslate produces a translation by (x, y, z ). The current matrix (see glMatrixMode) is
multiplied by this translation matrix, with the product replacing the current matrix, as
if glMultMatrix were called with the following matrix for its argument:
1 00x
0 10y
0 01z
0 00 1
If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn
after a call to glTranslate are translated.
Use glPushMatrix and glPopMatrix to save and restore the un-translated coordinate
system.
Errors
• GL_INVALID_OPERATION is generated if glTranslate is executed between the
execution of glBegin and the corresponding execution of glEnd.
