IPlane_DG Interface

A 3D plane defined by a point and a normal vector.

A standalone plane can be constructed via IObjectGenerator_DG.Create("IPlane_DG") > IPlane_DG query.

Implements also: IObject_DG.

Point_DG GetOrigin()


void SetOrigin(Point_DG origin)


Vect_DG GetNormal()


void SetNormal(Vect_DG normal)


bool Init(Point_DG point0, Point_DG point1, Point_DG point2)

Returns false if the points are not in general position and the initialisation has failed


IFrame_DG GetLocation()

Returns frame x,y plane of which is this plane and z axis is a normal.


void SetLocation(IFrame_DG frame)

Defines this plane as coinsiding with x,y plane of frame


double GetDistance(Point_DG point, out Point_DG pointNearestInPlane)

Returns distance from point. The out pointNearestInPlane is the nearest point on this plane


int GetPointLocation(Point_DG point, double tolerance)

Returns 0 is the point is inside the plane, 1 if is on the side where normal points to and -1 otherwise


bool GetLineIntersection(ILine_DG line, out Point_DG intersection, out double positionLine)

Returns false if line is parallel to this or lies in this. [out] positionLine is parameter along line, which is the distance from origin of the line.


ILine_DG GetPlaneIntersection(IPlane_DG plane)

Returns intersection line of the two planes.


void Mirror(ref Point_DG point)

Mirros [in,out] point across this plane.


void MirrorVector(ref Vect_DG vector)

Mirros [in,out] vector across this plane.


void MirrorLine(ref ILine_DG line)

Mirros [in,out] line across this plane.


void Copy(IPlane_DG plane)


IPlane_DG Clone()

Returns a new copy of this.


Point_DG GetPointProjection(Point_DG point)


Vect_DG GetVectorProjection(Vect_DG vector)


ILine_DG GetNormalRay(Vect_DG vector)

Returns a ray along the normal at the origin of this.
