Canvas 3d JS Library

A number of things have occurred that necessitate a new version of the motion capture demo. These include:

• The new release of the Canvas3D extension (0.4.2), and the corresponding release of our library(1.0).
• Andor’s work on points and lines.
• My continued work on converting c3d and trc files

As these new capabilities arrived, it became clear that the motion capture demo could be seriously improved.

The most visually apparent improvement is the inclusion of lines connecting some of the markers. This relied on Andor’s previously mentioned work, along with some extra functions in the conversion process to separate the markers by subject and try to match those subjects against pre-existing templates. It is also noticeable that some of the connections don’t make any sense (the actor’s foot being connected to the phone in the capture labeled ‘wrong number’, for example), this is because the data I used for the demo hasn’t been manually cleaned, and the motion capture system was under the mistaken impression that the marker in question actually did represent the actor’s ankle. This kind of problem is one of many things that is normally sorted out before a file is really ready to be used.
