Note I said it wrong, the top half has 5 teeth and it is from a gear with 10 teeth, and the bottom half has 6 teeth and it is from a gear with 12 teeth.

We are developing a few prototypes based on a New-CVT version with 9 conical involute gears and starting with 8 teeth. So we have optimized the source code for this version. In order to make sure that the prototypes were perfect in every detail, we made an animation of each gear in the main gear as it intermeshes with a pinion gear. They are close-up orthographic wire-frame projections of the intermeshing gears. Please use the source code if you want to zoom in even more or to look from different angels.
Note that the pinion in these animations has the same height as the gear in the main gear. This was done to be extra critical in testing the outer reaches. In reality the height of the pinion will be less, so the simulations are worse case scenarios.
