Physics based modeling and rendering for crystal growth using PhysBAM libraries.

Crystal growth simulation

My project for the course CS838 'Advanced Modeling and Simulation' taught by Eftychios Sifakis in the Fall of 2012. Currently, here are some of the implementations in the source code

* 3D implementation of Gradient augmented level set method (http://arxiv.org/abs/0905.3409) with tri-cubic Hermite interpolating polynomials.
* Semi-Lagrangian implementation of pde's for constant and linear extrapolations of scalar field across interface, originally proposed in 'A partial differential equation approach to multidimensional extrapolation, J. Comput. Phys. 193 (2004) 349-355'.
* Implemented in the framework of PhysBAM (http://physbam.stanford.edu/).
* Results can be rendered using Mitsuba (http://www.mitsuba-renderer.org/).

Make a movie

Scenes are rendered using Mitsuba and the scene file used in making a movie is included in the folder 'renderscene'.

movie.sh file gives a demonstration in using Mitsuba to render multiple scenes and to convert the resulting images into mp4.

Prerequisites in using movie.sh:

* exrtopng
* ffmpeg
