triangleNeighbors method

List<int> triangleNeighbors(
  1. int t
)

Returns the neighbor triangles for triangle t. Returns -1 for edges on the convex hull.

Implementation

List<int> triangleNeighbors(int t) {
  return [
    _triangleOfEdge(halfedges[t * 3]),
    _triangleOfEdge(halfedges[t * 3 + 1]),
    _triangleOfEdge(halfedges[t * 3 + 2]),
  ];
}
