Papervision 3D Figure-8’s

September 4, 2007

The 2D Lemniscate of Bernoulli example proved to be rather popular, so I thought a 3D extension would make a good test for the 3D closed-loop Catmull-Rom spline.  This example animates a series of markers (boxes) along three figure-8 paths in the XY, XZ, and YZ planes.

Arc-length parameterization produces smooth motion along all three paths.  The online demo may be viewed here, which includes a link to download the entire Singularity package.
