How to set property per (triangle, vertex) tuple?

[shikui08]

AFAIK, the function Manifold::SetProperties don't distinguish vertex shared by multiple triangles.

const int numTri = NumTri(); triProperties.resize(numTri); for (int i = 0; i < numTri; ++i) { for (const int j : {0, 1, 2}) { triProperties[i][j] = pImpl->halfedge_[3 * i + j].startVert; } }
Say I want a cube with sharp edges, so normal don't blend. How can I possibly do that?

I think you need to use MeshGL for this. Duplicate the vertices, and set the appropriate mergeFromVert and mergeToVert.

Thanks for your reply. Also checking test cases TEST(Boolean, Normals) in boolean_test.cpp. Seems to work this way.

Feel free to open a discussion if needed. Closing for now.
