high performance computing on graphics processing units: hgpu.org

This project’s aim is to find a WebGL based alternative to the Java implementation of OpenPixi, a Java-based Particle-in-Cell (PIC) simulation software, and to add a third dimension. For this purpose, an existing JavaScript library, three.js, was chosen. A handful of approaches are explored and the resulting prototypes are then compared in terms of speed, as performance is a main concern. A shader-based implementation, the best performing of the prototypes, is then explained in more detail and recommendations for the future development of OpenPixi are given.
