Calculate the area of a 3D triangular irregular network (TIN) mesh using the vertex and face list data. Note that most common file formats used to store TIN data (e.g. .obj / .ply) use zero indexing meaning that the face list will need to be converted to non-zero indexing in matlab:
faces = faces+ones(size(faces,1),3);


INPUT:
faces - mx3 face indexes of the mesh

points - nx3 vertex data of the mesh

OUTPUT:
areaTIN - mx1 triangular area measurements matched to face list
