Signature
Parameters
| Variables | Description |
|---|---|
| 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.
