void glTexCoord4fv(const GLfloat *v)
void glTexCoord4iv(const GLint *v)
void glTexCoord4sv(const GLshort *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

The current texture coordinates are part of the data that is associated with each vertex and with the current raster position. They are set with glTexCoord.

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).

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.
