Abstract: A method for efficiently injecting sources and retrieving receiver wavefields using finite difference models for wavefield simulations on a GPU, when the source and receiver are not on numerical grid points, and therefore arbitrarily located.

Abstract: Embodiments of the present invention provide a position-based dynamics approach for simulating objects using a set of points and constraints, applied as equations that restrict the relative motion of bodies. Forces are applied to the points to move them, and the constraints ensure that the points will not move in a way that is inconsistent with rules of the simulation. The present invention improves upon existing PBD approaches by using regularized constraints that directly correspond to well-defined energy potentials, and which can advantageously be solved independent of time step and iteration count.
