                    void glTexCoord4dv
                    const GLdouble * v

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

## Associated Gets

with argument `GL_CURRENT_TEXTURE_COORDS`
