Nvidia patents method to speed up object collision simulations
Nvidia describes a system that simplifies how computers calculate physical interactions between objects. It works by removing unnecessary data points from contact areas to make the simulation run faster on multiple processing threads.
In the filing’s own words
Systems and methods herein address scalable contact-rich simulation in physics engines using one or more processing units to simulate movement between at least two objects in a simulation, the movement based at least on a plurality of sets of reduced points obtained from an iterative reduction using one or more threshold criteria, the iterative reduction applied to a plurality of points associated with at least one contact between the depictions.
What exactly they claim (claim 1)
1. A system comprising one or more processing units to: receive a set of points associated with at least one contact between at least a first object and a second object in a simulation; determine, for individual points of the set of points, an angular separation and a gradient with respect to at least one other point of the set of points; perform, based at least on one or more threshold criteria regarding the angular separation and the gradient, an iterative discarding of one or more points from the set of points using a plurality of threads of the one or more processing units to determine a subset of points; and simulate movement between at least the first object and the second object based at least on the subset of points.
