Title:
SIMULATION DEVICE AND COLLISION JUDGEMENT METHOD
Document Type and Number:
Japanese Patent JP3138424
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform collision judgement with a complicated terrain obstacle present in a virtual three-dimensional space with less arithmetic loads.
SOLUTION: This device is provided with a terrain data storage part 160 for collision judgement for storing terrain data for the collision judgement and a collision judgement part 150 for performing the collision judgement of at least one hit check point for the collision judgement provided on a mobile object and a terrain object. The collision judgement part 150 is provided with a judgement object polygon detection part 152 for detecting a polygon including a hit checkpoint judgement point where a straight line including the hit check point parallel to a third coordinate axis is crossed with the polygon for constituting the terrain object and a height computing part 156 for computing the value of the third coordinate axis of the hit check point judgement point and the collision judgement is performed based on the size relation of the values of the third coordinate axis of the hit check point and the hit check point judgement point.
