pointToFraction Method

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

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

@returns details d of the projection point P = d.world:

• 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().
• Visualization can be found at https://www.itwinjs.org/sandbox/SaeedTorabi/BarycentricTriangle
