NAME    [Toc]    [Back]

       glColorPointer - define an array of colors

SYNOPSIS    [Toc]    [Back]

       void glColorPointer(
               GLint size,
               GLenum type,
               GLsizei stride,
               const GLvoid *pointer );

PARAMETERS    [Toc]    [Back]

       Specifies the number of components per color. Must be 3 or
       4. The initial value is 4.  Specifies  the  data  type  of
       each  color  component  in  the  array. Symbolic constants
       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.

DESCRIPTION    [Toc]    [Back]

       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 vertexes and attributes to be  packed
       into a single array or stored in separate arrays. (Singlearray
 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.

NOTES    [Toc]    [Back]

       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

       Color  array  parameters  are  client-side  state  and are
       therefore not saved  or  restored  by  glPushAttrib()  and
       glPopAttrib().      Use      glPushClientAttrib()      and
       glPopClientAttrib() instead.

ERRORS    [Toc]    [Back]

       GL_INVALID_VALUE is generated if size is not 3 or 4.

       GL_INVALID_ENUM is generated if type is  not  an  accepted

       GL_INVALID_VALUE is generated if stride is negative.

ASSOCIATED GETS    [Toc]    [Back]

       glIsEnabled() with argument GL_COLOR_ARRAY
       glGet() with argument GL_COLOR_ARRAY_SIZE
       glGet() with argument GL_COLOR_ARRAY_TYPE
       glGet() with argument GL_COLOR_ARRAY_STRIDE
       glGetPointerv with argument GL_COLOR_ARRAY_POINTER
