pointToFraction Method

Compute the projection of the given point onto the plane of this triangle.

pointToFraction(point: Point3d, result?: TriangleLocationDetail): TriangleLocationDetail

see BarycentricTriangle.fractionToPoint

Parameter Type Description
point Point3d point p to project
result TriangleLocationDetail optional pre-allocated object to fill and return

Returns - TriangleLocationDetail

details d of the projection point P = d.point:

  • d.isValid returns true if and only if this.normal() is defined.
  • d.classify can be used to determine where P lies with respect to the triangle.
  • d.a is the signed projection distance: P = p + a * this.normal().
