HI Kurt, Thanks for your email. This could be quite useful if the visualisation is faster using the consistent shape. Currently we tend to split all shapes into Tets (in 3D) and Tris (in 2D). So this would likely allow us to render our hybrid shapes more consistently. As always it is finding the time to play around with these developments that can be the limiting steps. Cheers, Spencer.

Consider me ignorant here.
