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 ARB_imaging extension is supported, glTexCoord always updates texture unit GL_TEXTURE0.
