PARAMETERS





v

Specifies a pointer to an array of one, two, three, or four elements,
which in turn specify the
s,
t,
r, and
q texture coordinates.


 

DESCRIPTION


glTexCoord specifies texture coordinates in
one,
two,
three, or
four dimensions.  
glTexCoord1 sets the current texture coordinates to
(s, 0, 0, 1);
a call to 



glTexCoord2 sets them to
(s, t, 0, 1).

Similarly, glTexCoord3 specifies the texture coordinates as
(s, t, r, 1), and
glTexCoord4 defines all four components explicitly as
(s, t, r, q). 

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 
s,
t,
r, and
q
are (0, 0, 0, 1). 

 

NOTES


The current texture coordinates can be updated at any time.
In particular,
glTexCoord can be called between a call to glBegin and the corresponding
call to glEnd.

When the GL_ARB_imaging extension is supported, glTexCoord always
updates texture unit GL_TEXTURE0_ARB.
