glColorPointer - define an array of colors
void glColorPointer(
GLint size,
GLenum type,
GLsizei stride,
const GLvoid *ptr )
eqn not supported
- 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 initial value), the colors
are understood to be tightly packed in the array. The initial value is 0.
- ptr
- Specifies a pointer to the first component of the first color element
in the array.
glColorPointer specifies the location and data
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.)
When a
color array is specified, size, type, stride, and ptr 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.
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 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.
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.
