.SH DESCRIPTION
|
||
|
|
\%\f3glMultiTexCoordARB\fP specifies texture coordinates in one, two, three, or four
|
||
|
|
dimensions.
|
||
|
|
\%\f3glMultiTexCoord1ARB\fP sets the current texture
|
||
|
|
coordinates to (\f2s\fP,\ 0,\ 0,\ 1);
|
||
|
|
a call to \%\f3glMultiTexCoord2ARB\fP
|
||
|
|
sets them to (\f2s\fP,\ \f2t\fP,\ 0,\ 1).
|
||
|
|
Similarly, \%\f3glMultiTexCoord3ARB\fP specifies the texture coordinates as
|
||
|
|
(\f2s\fP,\ \f2t\fP,\ \f2r\fP,\ 1), and
|
||
|
|
\%\f3glMultiTexCoord4ARB\fP
|
||
|
|
defines all four components explicitly as
|
||
|
|
(\f2s\fP,\ \f2t\fP,\ \f2r\fP,\ \f2q\fP).
|
||
|
|
.P
|
||
|
|
The current texture coordinates are part of the data
|
||
|
|
that is associated with each vertex and with the current
|
||
|
|
raster position.
|
||
|
|
Initially, the values for
|
||
|
|
\f2s\fP, \f2t\fP, \f2r\fP, \f2q\fP are (0,\ 0,\ 0,\ 1).
|
||
|
|
.P
|
||
|
|
.SH NOTES
|
||
|
|
\%\f3glMultiTexCoordARB\fP is only supported if \%\f3GL_ARB_multitexture\fP is included in the
|
||
|
|
string returned by \%\f3glGetString\fP when called with the argument
|
||
|
|
\%\f3GL_EXTENSIONS\fP.
|
||
|
|
.P
|
||
|
|
The current texture coordinates can be updated at any time.
|
||
|
|
In particular,
|
||
|
|
\%\f3glMultiTexCoordARB\fP can be called between a call to \%\f3glBegin\fP and the corresponding
|
||
|
|
call to \%\f3glEnd\fP.
|
||
|
|
.P
|
||
|
|
It is always the case that \%\f3GL_TEXTURE\fP$i$\f3_ARB\fP = \%\f3GL_TEXTURE0_ARB\fP + $i$.
|
||
|
|
.SH ASSOCIATED GETS
|
||
|
|
\%\f3glGet\fP with argument \%\f3GL_CURRENT_TEXTURE_COORDS\fP with appropriate
|
||
|
|
texture unit selected.
