glColorPointer(3G)glColorPointer(3G)NAMEglColorPointer - define an array of colors
SYNOPSIS
void glColorPointer(
GLint size,
GLenum type,
GLsizei stride,
const GLvoid *pointer );
PARAMETERS
Specifies the number of components per color. Must be 3 or 4. The ini‐
tial value is 4. 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. 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. Specifies a pointer to the first component of the first
color element in the array.
DESCRIPTIONglColorPointer() specifies the location and data of an array of color
components to use when rendering. size specifies the number of compo‐
nents 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 vertexes 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 pointer 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.
NOTESglColorPointer() is available only if the GL version is 1.1 or greater.
The color array is initially disabled and isn't accessed when glAr‐
rayElement(), glDrawArrays(), glDrawRangeElements(), or glDrawEle‐
ments() 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 glPushClien‐
tAttrib() 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.
