Patent ID: 7663630

Claim:
An apparatus for processing collision information in a graphic system, comprising: a collision object information storage unit for loading geometry information of primary object graphics 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 collision object information 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 collision information operation processor for acquiring a collision point, collision presence information, and a collision depth between the primary object graphics and the secondary object graphics simultaneously based on the geometry information of the inputted primary object graphics and the geometry information 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 object graphics and the secondary object graphics; a collision information storage unit for storing the collision point, the collision presence information, and the collision depth separately, wherein a collision depth before an update and a collision depth after the update are stored in two areas separately; and a collision information updating unit for updating the collision point and the collision presence information whenever the collision point and the collision presence information are newly outputted from the collision information operation processor, wherein the collision depth is updated based on the result of comparison with the previously stored collision depth.
