how to check if all the faces face outward

Trending 2 months ago

Situation: I americium utilizing Open3D python,The mesh procreation algorithm ( for illustration shot pivot, poisson reconstruction ) are limited connected normal direction. I utilized estimate_normals and orient_normals_consistent_tangent_plane methods connected nan constituent unreality to make judge vertex normals are facing outward. After generating nan mesh, one want to cheque if nan look normals are facing outward. If not, I request to flip it.

Help : really to correspond "outward" information for a look normal, mathematically. I tin get look normal from mesh.triangle_normals.

context : I americium rookie engineer, truthful Any links to mentation aliases examples would thief maine understand. open3d solution is besides invited :)
