Currently only Triangle Lists are supported via the TriangleMesh class.

D3D9 [1], D3D10+ [2], Metal [3], Vulkan [4] and OpenGL [5] all support these additional primitives:
Point List
Line List
Line Strip
Triangle Strip

Implementation could be difficult, for example, intersection computation. Point List might have a simpler implementation so would be a good starting point.

Triangle Fan was removed in D3D10 and is not supported in Metal. There is no good reason to consider it.
