Once a display list is created, all vertex and pixel data are evaluated and copied into the display list memory on the server machine. In certain situations, calls to glColor appear to be ignored, resulting in objects being displayed with the incorrect color. An additional level of indirection is made available with the glListBase command, which specifies an unsigned offset that is added to each display-list name specified in lists before that display list is executed. With glDrawArrays, OpenGL pulls data from the enabled arrays in order, vertex 0, then vertex 1, then vertex 2, and so on. You should try to make the question a tad more clear but as I gather your attempting to create a call list. Either by: 1) ray-casting against your scene on the [edit:] CPU, or 2) rendering all of your objects to the screen with a unique color per object, doing a glReadPixels of the resulting image, and using that for picking.
