## 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**.

## ASSOCIATED GETS
