C SPECIFICATION

10       void glColorPointer( GLint size,
11                            GLenum type,
12                            GLsizei stride,
13                            const GLvoid *ptr )

15

PARAMETERS

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

DESCRIPTION

33       glColorPointer specifies the location and data  of an  array  of  color
34       components  to use when rendering.  size specifies the number of compo‐
35       nents per color, and must be 3 or 4.  type specifies the data  type  of
36       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
39       be more efficient on some implementations; see glInterleavedArrays.)
40
41       When a color array is specified, size, type, stride, and ptr are  saved
42       as client-side state.
43
44       To enable and disable the color array, call glEnableClientState and
45       glDisableClientState  with the argument GL_COLOR_ARRAY. If enabled, the
46       color   array    is    used    when    glDrawArrays,    glDrawElements,
47       glDrawRangeElements, or glArrayElement is called.
48

NOTES

50       glColorPointer is available only if the GL version is 1.1 or greater.
51
52       The   color  array  is  initially  disabled  and  isn't  accessed  when
53       glArrayElement, glDrawArrays, glDrawRangeElements, or glDrawElements is
54       called.
55
56       Execution  of  glColorPointer  is  not allowed between the execution of
57       glBegin and the corresponding execution of glEnd, but an error  may  or
58       may  not be generated. If no error is generated, the operation is unde‐
59       fined.
60
61       glColorPointer is typically implemented on the client side.
62
63       Color array parameters are client-side  state  and  are  therefore  not
64       saved    or    restored   by   glPushAttrib   and   glPopAttrib.    Use
65       glPushClientAttrib and glPopClientAttrib instead.
66

ERRORS

68       GL_INVALID_VALUE is generated if size is not 3 or 4.
69
70       GL_INVALID_ENUM is generated if type is not an accepted value.
71
72       GL_INVALID_VALUE is generated if stride is negative.
