TRIMESH likely doesnt work.

[Glidias]

TriMesh uses Float32Array for the vertices, but SparkAR doesn't seem to support TypedArrays out of the box. (strange...dunno why). Of course, there may be polyfills available though that the user may download on his own in the unlikely case they use trimesh. The "official" package published on Spark AR Library appears ot have this issue if you use something like:
CANNON.Trimesh.createTorus(4, 3.5, 16, 16); . But from the typehintings, Trimesh seems to be unavailable and not found in intellisense though..even though you can still call it remotely.
