NAME

6       glTexCoordPointer - define an array of texture coordinates
7

C SPECIFICATION

9       void glTexCoordPointer(GLint size, GLenum type, GLsizei stride,
10                              const GLvoid * pointer);
11

PARAMETERS

13       size
14           Specifies the number of coordinates per array element. Must be 1,
15           2, 3, or 4. The initial value is 4.
16
17       type
18           Specifies the data type of each texture coordinate. Symbolic
19           constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted.
20           The initial value is GL_FLOAT.
21
22       stride
23           Specifies the byte offset between consecutive texture coordinate
24           sets. If stride is 0, the array elements are understood to be
25           tightly packed. The initial value is 0.
26
27       pointer
28           Specifies a pointer to the first coordinate of the first texture
29           coordinate set in the array. The initial value is 0.

DESCRIPTION

32       glTexCoordPointer specifies the location and data format of an array of
33       texture coordinates to use when rendering.  size specifies the number
34       of coordinates per texture coordinate set, and must be 1, 2, 3, or 4.
35       type specifies the data type of each texture coordinate, and stride
36       specifies the byte stride from one texture coordinate set to the next,
37       allowing vertices and attributes to be packed into a single array or
38       stored in separate arrays. (Single-array storage may be more efficient
39       on some implementations; see glInterleavedArrays().)
40
41       If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER
42       target (see glBindBuffer()) while a texture coordinate array is
43       specified, pointer is treated as a byte offset into the buffer object's
44       data store. Also, the buffer object binding (GL_ARRAY_BUFFER_BINDING)
45       is saved as texture coordinate vertex array client-side state
46       (GL_TEXTURE_COORD_ARRAY_BUFFER_BINDING).
47
48       When a texture coordinate array is specified, size, type, stride, and
49       pointer are saved as client-side state, in addition to the current
50       vertex array buffer object binding.
51
52       To enable and disable a texture coordinate array, call
53       glEnableClientState() and glDisableClientState() with the argument
54       GL_TEXTURE_COORD_ARRAY. If enabled, the texture coordinate array is
55       used when glArrayElement(), glDrawArrays(), glMultiDrawArrays(),
56       glDrawElements(), glMultiDrawElements(), or glDrawRangeElements() is
57       called.
58

NOTES

60       glTexCoordPointer is available only if the GL version is 1.1 or
61       greater.
62
63       For OpenGL versions 1.3 and greater, or when the ARB_multitexture
64       extension is supported, glTexCoordPointer updates the texture
65       coordinate array state of the active client texture unit, specified
66       with glClientActiveTexture().
67
68       Each texture coordinate array is initially disabled and isn't accessed
69       when glArrayElement(), glDrawElements(), glDrawRangeElements(),
70       glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
71       called.
72
73       Execution of glTexCoordPointer is not allowed between the execution of
74       glBegin() and the corresponding execution of glEnd(), but an error may
75       or may not be generated. If no error is generated, the operation is
76       undefined.
77
78       glTexCoordPointer is typically implemented on the client side.
79
80       Texture coordinate array parameters are client-side state and are
81       therefore not saved or restored by glPushAttrib() and glPopAttrib().
82       Use glPushClientAttrib() and glPopClientAttrib() instead.
83

ERRORS

85       GL_INVALID_VALUE is generated if size is not 1, 2, 3, or 4.
86
87       GL_INVALID_ENUM is generated if type is not an accepted value.
88
89       GL_INVALID_VALUE is generated if stride is negative.
