ProjectPointOnLine (FUN)¶

FUNCTION ProjectPointOnLine : BOOL

This function will project the point \(x \in \mathbb{R^{3}}\) onto a straight line: thereby, the direction vector of the straight line is taken as normal vector of a plane that is moved along the line as long as it touches the point \(x\). The intersection point of the plane with the line corresponding to this location is the projected point.

InOut:

Scope	Name	Type	Comment

Input	pline	POINTER TO LINE_3D	Pointer on straight line
	pvOrig	POINTER TO Vector3D	Pointer on point \(x\) to be projected
	pvProj	POINTER TO Vector3D	Pointer to projected result
