Abstract (en)
[origin: WO2005093610A2] The invention relates to a method for the interactive simulation of contact between objects. The inventive method comprises the following steps, namely: the parameters describing the physical characteristics of each of the objects are calculated; at the beginning of each simulated model sampling time period, each object is subjected to a real-time analysis of the specific behaviour thereof according to a free movement that does not take account of possible subsequent contacts, and, subsequently, at a global scene level, pairs of detected intersecting objects are subjected to a real-time analysis; a list of collision groups is established; for each collision group, parameters representing the physical characteristics of the objects and the description of the collisions are returned in real time, such as to characterise the contact between two objects in the case of a pure relative sliding movement; and, for each object, the specific behaviour of the object following the collision is displayed in real time and the set of real-time processes is performed with a shorter calculation time than the sampling time.
