You mentioned 3D visualization in which, as far as I know, 4D homogeneous coordinates are commonly used.

In viz I ran into needing quaternions specifically. In neuroscience I've needed that and also e.g. computing the angle between two rotation matrices (or quaternions), among other things. </div></div></div></div><div><div class="gmail_extra"><div class="gmail_quote"><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-size:10pt;font-family:Verdana,Arial,Helvetica,sans-serif"><div>Great that you are interested in mentoring this project as well. I will add the idea in a basic form to the wiki. Generally I think we should leave some space for a student to investigate, instead of specifying absolutely everything.
