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 Return ProjectPointOnLine BOOL 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
CalcHesseRepresentation (FB) ¶ FUNCTION_BLOCK CalcHesseRepresentation This function block will retrieve the normal form (due to Hesse) of a plane \(E\) in the three dimensional space: \(E\colon(x-p)\cdot n = 0\) , where \(n\) is the normed normal on the plane and \(p\) a point on the plane. The plane is originally specified by three of its points. InOut: Scope Name Type Comment Input vP1 POINTER TO Vector3D point on plane \(E\) vP2 POINTER TO Vector3D point on plane \(E\) vP3 POINTER TO Vector3D point on plane \(E\) Output plane PLANE_H normal form of plane \(E\) xError BOOL Error flag TRUE : If input points are collinear
ProjectPointOnPlane (FUN) ¶ FUNCTION ProjectPointOnPlane : LREAL This function will project a point \(x \in \mathbb{R^{3}}\) onto a plane in direction of the normal vector. The return is the distance of the point \(x\) to the plane. InOut: Scope Name Type Comment Return ProjectPointOnPlane LREAL Input pplane POINTER TO Plane_H Pointer on plane description pvOrig POINTER TO VECTOR3D Pointer on point \(x \in \mathbb{R^{3}}\) to be projected pvProj POINTER TO VECTOR3D Pointer on projection of \(x\) onto plane
CartesianToPolar (FB) ¶ FUNCTION_BLOCK CartesianToPolar This function block will change the Cartesian coordinates of the two dimensional space \((x,y) \in \mathbb{R^{2}}\) , to polar coordinates \((r, \varphi) \in \mathbb{R_{0}^{+}} \times \left( -\pi, \pi\right]\) , which are connected via: \[ \begin{align}\begin{aligned}r=\sqrt{x^{2} + y^{2}}\\\varphi = \arctan\left(y, x\right)\end{aligned}\end{align} \] InOut: Scope Name Type Comment Input lrX LREAL X coordinate \(x\) lrY LREAL Y coordinate \(y\) Output lrAngle LREAL Angular coordinate \(\varphi\) (azimuth) lrDistance LREAL Radius \(r\)
