		const size_t *	vi,

	)

TriangleMesh Constructor.

Date

2015/Aug/21

Parameters

o2w	Object to World transform matrix.
w2o	World to Object transform matrix.
ro	indicates if the surface normal should be reversed.
nt	is the number of triangles.
nv	is the number of vertices.
vi	is a pointer to an array of vertex indices. For the ith triangle, its three vertex positions are P[vi[3*i]],P[vi[3*i+1]], and P[vi[3*i+2]];
p	is an array of nv vertex positions.
n	is an optional array of normal vectors, one per vertex in the mesh. If present, these are interpolated across triangle faces to compute shading differential geometry.
s	is an optional array of tangent vectors, one per vertex in the mesh. These are also used to compute shading geometry.
uv	is an optional array of parametric (u,v) values, one for each vetex.
atex	is an optional Alpha Mask texture, which can be used to cut away part of the triangle's surface.
