What is the blog?

This blog is a re-interpretation of the tessendorf.org website I had for several years. At the moment I am putting up the papers and reports page. Eventually I will put up the other pages on frumple and old Arete Image Software materials. You can also find this information at my university page

The Characteristic Map for Fast and Efficient VFX Fluid Simulations

The Method of Characteristics is examined as a tool for making fluid simulation more efficient and effective in VFX production. A mathematical frame- work for a Characteristic Map is shown to be a general- ization of the previous methods called Gridless Advec- tion and Semi-Lagrangian Mapping. We demonstrate that the Characteristic Map can be used to modify a fluid flow post-simulation, including injecting higher resolution motion, and precise flow control from blend- ing Characteristic Maps.
