- define an array of colors
C SPECIFICATION
PARAMETERS
_param1 Specifies the number of components per color.
Must be 3 or 4. The initial value is 4.
_param2 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.
_param3 Specifies the byte offset between consecutive
colors. If _param3 is 0 (the initial value), the
colors are understood to be tightly packed in the
array. The initial value is 0.
_param4 Specifies a pointer to the first component of the
first color element in the array.
DESCRIPTION
glColorPointer specifies the location and data of an
array of color components to use when rendering. _param1
specifies the number of components per color, and must be
3 or 4. _param2 specifies the data type of each color
component, and _param3 specifies the byte stride from one
color to the next allowing vertexes and attributes to be
packed into a single array or stored in separate arrays.
(Single-array storage may be more efficient on some imple-
mentations; see glInterleavedArrays.)
When a color array is specified, _param1, _param2,
_param3, and _param4 are saved as client-side state.
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,
glDrawElements, 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, glDrawArrays, glDrawRangeElements, or
glDrawElements is called.
Execution of glColorPointer is not allowed between the
GL_INVALID_ENUM is generated if _param2 is not an accepted
value.
GL_INVALID_VALUE is generated if _param3 is negative.
