Demonstration of Implemented Features

First step

particlemotion.scn

effectofgravity.scn

effectofdrag.scn

The animations in this write-up have been created as animated gif files, using a variation of the command

 convert -delay 4 -loop 0 video-frames/frame*.jpg video.gif

which is available on most Linux platforms and can be installed on the Mac OS X platform with the instructions found here. If you cannnot create animated .gif files, you may alternatively submit an MPEG (or MPEG4) compressed video created with any software of your choice. In that case, please link it accordingly.

Comments about the implementation, pecularities, etc.

Particle sources

spheresource.scn	circlesource.scn	boxsource.scn
linesource.scn	conesource.scn	meshsource.scn

Comments about the implementation, pecularities, etc.

Particle sinks

spheresink.scn	circlesink.scn	boxsink.scn
linesink.scn	conesink.scn	meshsink.scn

Comments about the implementation, pecularities, etc.

Particle simulation

differentlifetimes.scn	eulervsadaptive.scn	eulervsadaptive.scn
eulervsmidpoint.scn	eulervsmidpoint.scn

For the eulervsadaptive.scn, construct a scene which has visible problems for naive Euler integration, but works as niceley for adaptive step sizes; do the analogous for eulervsmidpoint.scn
