  • Method Details

    • setTriangle

      public void setTriangle(Point3D_F64 p0, Point3D_F64 p1, Point3D_F64 p2)

    • closestPoint

      public void closestPoint(Point3D_F64 P, Point3D_F64 closestPt)
      Find the closest point on the triangle to P.
      Parameters:
      P - Input. The point for which the closest point is to be found.
      closestPt - Output. The found closest point.

    • sign

      public double sign(Point3D_F64 P)
      Returns the signed of the vector. If its "in front" it will be positive and negative if "behind". In front is defined as being on the same side as the cross product of p2-p0 and p1-p0.
      Parameters:
      P - Point for which the sign is determined
