- An apparatus processes collision information in a graphic system, and includes a first storage unit for loading geometry information of primary and secondary object graphics inputted from outside, and outputting the geometry information of the primary object graphics and geometry information of a plurality of secondary object graphics in which a collision detection operation with the primary object graphics is to be performed; a transformer for transforming coordinates of the secondary object graphics to be coincided with a coordinate system that is based on the primary object graphics; a processor for acquiring a collision point, collision presence information, and a collision depth between the primary and the secondary object graphics simultaneously based on the geometry information of the inputted primary object graphics and that of each of the coordinate-transformed secondary object graphics by using a collision detection operation technique determined by the geometry information properties of the primary and the secondary object graphics; a second storage unit for storing the collision information separately, wherein the collision depths before/after update are stored in two areas separately; and an updating unit for updating the collision point and the collision presence information whenever they are newly outputted from the processor, wherein the collision depth is updated based on the result of comparison with the previously stored collision depth.
