Abstract
A plurality of graphics objects are assigned to a quad-tree structure corresponding to a display. It is determined whether another graphics object overlaps with a display area corresponding to a node of the quad-tree structure. When the other graphics object overlaps with the display area, it is determined whether the other graphics object intersects with any graphics objects belonging to the node.
