Name

glTexCoordPointer - define an	array of texture coordinates

Python Specification

glTexCoordPointer
	glTexCoordPointer(size, type, stride, pointer) -> None
glTexCoordPointerb
	glTexCoordPointerub(pointer[][]) -> None
glTexCoordPointerd
	glTexCoordPointerd(pointer[][]) -> None
glTexCoordPointerf
	glTexCoordPointerf(pointer[][]) -> None
glTexCoordPointeri
	glTexCoordPointeri(pointer[][]) -> None
glTexCoordPointers
	glTexCoordPointers(pointer[][]) -> None

C Specification

void glTexCoordPointer( GLint	size,
                        GLenum type,
                        GLsizei stride,
                        const	GLvoid *pointer	)

Parameters

size	   Specifies the number	of coordinates per array
         element. Must be 1, 2, 3 or 4. The initial value is
         4.

type	   Specifies the data type of each texture coordinate.
         Symbolic constants GL_SHORT,	GL_INT,	GL_FLOAT, or
         GL_DOUBLE are accepted. The initial value is
         GL_FLOAT.

stride   Specifies the byte offset between consecutive array
         elements.  If stride	is 0, the array	elements are
         understood to be tightly packed. The	initial	value
         is 0.

pointer  Specifies a pointer to the first coordinate of the
         first element in the	array.

Description

glTexCoordPointer specifies the location and data format of
an array of texture coordinates to use when rendering.  size
specifies the	number of coordinates per element, and must be
1, 2,	3, or 4.  type specifies the data type of each texture
coordinate and stride	specifies the byte stride from one
array	element	to the next allowing vertexes and attributes
to be	packed into a single array or stored in	separate
arrays.  (Single-array storage may be	more efficient on some
implementations; see
glInterleavedArrays.)	 When a	texture	coordinate array is
specified, size, type, stride, and pointer are saved
client-side state.

To enable and	disable	the texture coordinate array, call
glEnableClientState and glDisableClientState with the
argument GL_TEXTURE_COORD_ARRAY. If enabled, the texture
coordinate array is used when	glDrawArrays, glDrawElements
or
glArrayElement is called.

Use glDrawArrays to construct	a sequence of primitives (all
of the same type) from prespecified vertex and vertex
attribute arrays.  Use glArrayElement	to specify primitives
by indexing vertexes and vertex attributes and
glDrawElements to construct a	sequence of primitives by
indexing vertexes and	vertex attributes.

Notes

glTexCoordPointer is available only if the GL	version	is 1.1
or greater.

The texture coordinate array is initially disabled and it
won't	be accessed when
glArrayElement, glDrawElements or glDrawArrays is called.

Execution of glTexCoordPointer is not	allowed	between	the
execution of glBegin and the corresponding execution of
glEnd, but an	error may or may not be	generated. If no error
is generated,	the operation is undefined.

glTexCoordPointer is typically implemented on	the client
side with no protocol.

The texture coordinate array parameters are client-side
state	and are	therefore not saved or restored	by
glPushAttrib and glPopAttrib.	 Use glPushClientAttrib	and
glPopClientAttrib instead.

Errors

GL_INVALID_VALUE is generated	if size	is not 1, 2, 3,	or 4.

GL_INVALID_ENUM is generated if type is not an accepted
value.

GL_INVALID_VALUE is generated	if stride is negative.

Associated Gets

glIsEnabled with argument GL_TEXTURE_COORD_ARRAY
glGet	with argument GL_TEXTURE_COORD_ARRAY_SIZE
glGet	with argument GL_TEXTURE_COORD_ARRAY_TYPE
glGetPointerv	with argument GL_TEXTURE_COORD_ARRAY_POINTER
