Method Detail

• normalToTriangle

  public static Coordinate normalToTriangle(Coordinate p0,
                                            Coordinate p1,
                                            Coordinate p2)

  Computes the normal vector to the triangle p0-p1-p2. In order to compute the normal each triangle coordinate must have a Z value. If this is not the case, the returned Coordinate will have NaN values. The returned vector has unit length.

  Parameters:

  p0 -

  p1 -

  p2 -

  Returns:

• normalize

  public static void normalize(Coordinate v)

• crossProduct

  public static Coordinate crossProduct(Coordinate v1,
                                        Coordinate v2)

• dotProduct

  public static double dotProduct(Coordinate v1,
                                  Coordinate v2)

• det

  public static double det(double a1,
                           double a2,
                           double b1,
                           double b2)
