Reading normals doesn't work correctly with certain file formats
When reading a file via MeshIO::read()
that has vertex normals or other data attached to it, the normals may not be useeable in the render delegate. See https://gitlab.kitware.com/iMSTK/iMSTK/-/blob/master/Source/Geometry/imstkGeometryUtilities.cpp#L268 for where this probably needs to be fixed
- normals are expected to be double
- tangents are expected to be double
- tcoords are expected to be float
