Description:
This video demonstrates a semi-Lagrangian surface tracking method for use with fluid simulations. The method maintains an explicit polygonal mesh that defines the surface, and an octree data struc-ture that provides both a spatial index for the mesh and a means for evaluating the signed-distance function away from the surface. At each time step, the surface is reconstructed from an implicit function defined by composition of backward advection and the current signed-distance function. One of the primary advantages of this for-mulation is that it enables tracking of surface characteristics, such as color or texture coordinates, at negligable additional cost.
