Landon Boyd :: Course Work

Here are the courses I've attended at UBC and some pretty pictures.


CPSC 521 (Parallel Algorithms and Architectures), Sep. - Dec. 2009

Instructor: Alan Wagner

For this course, I implemented a parallel Poisson solver using SOR and MPI. Here is my report and slides for a short presentation given to the class.


CPSC 548 (Directed Studies in Physics-based Animation), Jan. - Apr. 2009

Instructor: Robert Bridson

Here is a video of a damped spring, fixed on one end, swinging under the influence of gravity. My application can simulate an undamped or critically damped spring with specified spring constant. I implemented several time integration schemes so it can handle highly damped springs with reasonable timesteps:

For my term project, I extended Robert Bridson's FLIP fluid code to emit smoke and started investigating two-phase flow. Here is an example of smoke rising past an invisible circular obstacle.


CPSC 516 (Computational Geometry), Jan. - Apr. 2009

Instructor: Sergey Bereg

For this course, I studied the linear time polygon triangulation algorithms of Chazelle [1991] and Amato et al. [2000]. I attempted to implement the latter but unfortunately ran out of time. Here is my report and presentation, and this is what the resulting triangulation would have looked like.


CPSC 406 (Computational Optimization), Jan. - Apr. 2009

Instructor: Michael Friedlander

No pretty pictures for this course!


CPSC 524 (Digital Geometry Processing), Sep. - Dec. 2008

Instructor: Alla Sheffer

Here are some screen shots of the mesh deformation Graphite plugin I implemented using techniques from papers such as ["Laplacian Surface Editing", Sorkine et al 2004].

For our project, Massih Khorvash and I implemented a marching-cubes based surface reconstruction algorithm by Hoppe et al (1992). Here are some screen shots. The full report is available.

I also presented an overview of the Eigencrust surface reconstruction algorithm by Kolluri et al (2004).


CPSC 542g (Scientific Computing -- Graduate Breadth), Sep. - Dec. 2008

Instructor: Robert Bridson

The second and third images below were generated using radial basis function interpolation over randomly sampled points in the first image.


CPSC 340 (Machine Learning), Sep. - Dec. 2008

Instructor: Nando de Freitas

Here is the outcome of image compression using a truncated singular value decomposition. In this case, the image on the right is encoded using about 1/5 the data as the image on the left.
