.SH DESCRIPTION
|
||
|
|
\%\f3glTranslate\fP produces a translation by
|
||
|
|
$("x","y","z")$.
|
||
|
|
The current matrix
|
||
|
|
(see
|
||
|
|
.br
|
||
|
|
\%\f3glMatrixMode\fP)
|
||
|
|
is multiplied by this translation matrix,
|
||
|
|
with the product replacing the current matrix, as if
|
||
|
|
\%\f3glMultMatrix\fP were called with the following matrix
|
||
|
|

If the matrix mode is either \%\f3GL_MODELVIEW\fP or \%\f3GL_PROJECTION\fP,
|
||
|
|
all objects drawn after a call to \%\f3glTranslate\fP are translated.
|
||

.P
|

|
|
Use \%\f3glPushMatrix\fP and
|

\%\f3glPopMatrix\fP to save and restore
|
||
|
|
the untranslated coordinate system.

is executed between the execution of \%\f3glBegin\fP

and the corresponding execution of \%\f3glEnd\fP.
