Yes, it is - everything more complex than a single triangle is turned
into either a group of triangles or a TriMesh.

The TriMesh is always going to be our fast-path through the system, so
if you can arrange your data in that form you'll remove a couple of
overheads.


Geometries will maintain a TriMesh form of themselves automatically, but
to do so takes a bit of memory (the TriMesh has its own copy of the
geometry data), and takes a bit of time (depending on the geometry, the
TriMesh may need to be recalculated as often as every frame: e.g., if it
was some kind of implicit surface then it may need to be recalculated to
reflect the subdivision style).

=46or a TriGrid we'll only recalculate if you change the TriGrid data in
some way, but if you could submit as a TriMesh you'd avoid the memory
overhead.
