NAME

6       glColorPointer - define an array of colors
7

C SPECIFICATION

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

PARAMETERS

13       size
14           Specifies the number of components per color. Must be 3 or 4. The
15           initial value is 4.
16
17       type
18           Specifies the data type of each color component in the array.
19           Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT,
20           GL_UNSIGNED_SHORT, GL_INT, GL_UNSIGNED_INT, GL_FLOAT, and GL_DOUBLE
21           are accepted. The initial value is GL_FLOAT.
22
23       stride
24           Specifies the byte offset between consecutive colors. If stride is
25           0, the colors are understood to be tightly packed in the array. The
26           initial value is 0.
27
28       pointer
29           Specifies a pointer to the first component of the first color
30           element in the array. The initial value is 0.

DESCRIPTION

33       glColorPointer specifies the location and data format of an array of
34       color components to use when rendering.  size specifies the number of
35       components per color, and must be 3 or 4.  type specifies the data type
36       of each color component, and stride specifies the byte stride from one
37       color to the next, allowing vertices and attributes to be packed into a
38       single array or stored in separate arrays. (Single-array storage may be
39       more efficient 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 color array is specified, pointer
43       is treated as a byte offset into the buffer object's data store. Also,
44       the buffer object binding (GL_ARRAY_BUFFER_BINDING) is saved as color
45       vertex array client-side state (GL_COLOR_ARRAY_BUFFER_BINDING).
46
47       When a color array is specified, size, type, stride, and pointer are
48       saved as client-side state, in addition to the current vertex array
49       buffer object binding.
50
51       To enable and disable the color array, call glEnableClientState() and
52       glDisableClientState() with the argument GL_COLOR_ARRAY. If enabled,
53       the color array is used when glDrawArrays(), glMultiDrawArrays(),
54       glDrawElements(), glMultiDrawElements(), glDrawRangeElements(), or
55       glArrayElement() is called.
56

NOTES

58       glColorPointer is available only if the GL version is 1.1 or greater.
59
60       The color array is initially disabled and isn't accessed when
61       glArrayElement(), glDrawElements(), glDrawRangeElements(),
62       glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
63       called.
64
65       Execution of glColorPointer is not allowed between the execution of
66       glBegin() and the corresponding execution of glEnd(), but an error may
67       or may not be generated. If no error is generated, the operation is
68       undefined.
69
70       glColorPointer is typically implemented on the client side.
71
72       Color array parameters are client-side state and are therefore not
73       saved or restored by glPushAttrib() and glPopAttrib(). Use
74       glPushClientAttrib() and glPopClientAttrib() instead.
75

ERRORS

77       GL_INVALID_VALUE is generated if size is not 3 or 4.
78
79       GL_INVALID_ENUM is generated if type is not an accepted value.
80
81       GL_INVALID_VALUE is generated if stride is negative.
82
