NAME
glColorPointer - define an array of colors
C SPECIFICATION
void glColorPointer(GLint size, GLenum type, GLsizei stride,
const GLvoid * pointer);
PARAMETERS
size
Specifies the number of components per color. Must be 3 or 4. The
initial value is 4.
type
Specifies the data type of each color component in the array.
Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT,
GL_UNSIGNED_SHORT, GL_INT, GL_UNSIGNED_INT, GL_FLOAT, and GL_DOUBLE
are accepted. The initial value is GL_FLOAT.
stride
Specifies the byte offset between consecutive colors. If stride is
0, the colors are understood to be tightly packed in the array. The
initial value is 0.
pointer
Specifies a pointer to the first component of the first color
element in the array. The initial value is 0.
DESCRIPTION
glColorPointer specifies the location and data format of an array of
color components to use when rendering. size specifies the number of
components per color, and must be 3 or 4. type specifies the data type
of each color component, and stride specifies the byte stride from one
color to the next, allowing vertices 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().)
If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER
target (see glBindBuffer()) while a color array is specified, pointer
is treated as a byte offset into the buffer object's data store. Also,
the buffer object binding (GL_ARRAY_BUFFER_BINDING) is saved as color
vertex array client-side state (GL_COLOR_ARRAY_BUFFER_BINDING).
When a color array is specified, size, type, stride, and pointer are
saved as client-side state, in addition to the current vertex array
buffer object binding.
To enable and disable the color array, call glEnableClientState() and
glDisableClientState() with the argument GL_COLOR_ARRAY. If enabled,
the color array is used when glDrawArrays(), glMultiDrawArrays(),
glDrawElements(), glMultiDrawElements(), glDrawRangeElements(), or
glArrayElement() is called.
NOTES
glColorPointer is available only if the GL version is 1.1 or greater.
The color array is initially disabled and isn't accessed when
glArrayElement(), glDrawElements(), glDrawRangeElements(),
glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
called.
Execution of glColorPointer 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.
glColorPointer is typically implemented on the client side.
Color 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 3 or 4.
GL_INVALID_ENUM is generated if type is not an accepted value.
GL_INVALID_VALUE is generated if stride is negative.
