Eigen vector normal to a plane in c++

WebConsider the plane, P, in R 3 given by the vector equation: x (s, t) = (1, − 1, 2) + s (1, 0, 1) + t (1, − 1, 0); s, t ∈ R. (a) Compute a unit normal vector, n, to this plane. 1 mark (b) Define a linear transformation P: R 1 → R 3 by projection onto n: P (x) == proj n (x); x ∈ R 3 Compute the standard matrix, A, of P. 3 marks (c) Let ... WebApr 30, 2024 · If the points are specified in a counter-clockwise order as seen from a direction opposing the normal, then it's simple to calculate: Dir = (B - A) x (C - A) Norm = Dir / len (Dir) where x is the cross product. If you're using OpenTK or XNA (have access to the Vector3 class), then it's simply a matter of:
