.SH PARAMETERS
.TP \w'\f2x\fP\ \f2y\fP\ \f2z\fP\ \ 'u
\f2x\fP, \f2y\fP, \f2z\fP
Specify the \f2x\fP, \f2y\fP, and \f2z\fP coordinates of a translation vector.
.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
for its argument:

.EQ
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 { "x"~ above "y"~ above "z"~ above 1}
} ~~right )

.RE
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.
.SH ERRORS
\%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glTranslate\fP
is executed between the execution of \%\f3glBegin\fP
and the corresponding execution of \%\f3glEnd\fP.
