Constructor Summary

Geometry()

 

Method Summary
static Angle	angle(Point3D P1, Point3D O, Point3D P2)           calculate angle among three points in 3D space note: calling Point3D.distSquare() is more efficient than Point3D.distance().
static double	distance(Point3D P1, Point3D P2)           calculate distance between two points in 3D space
static GeoVector3D	project(GeoVector3D va, GeoVector3D vb)           return the projection of va on vb
static GeoVector3D	subtract(GeoVector3D va, GeoVector3D vb)           Return a geometric vector that is the result of subtracting second input geometric vector from the first one.
static GeoVector3D	sum(GeoVector3D va, GeoVector3D vb)           Return a geometric vector that is the result of summation of two input geometric vectors
static Angle	torsionAngle(Point3D P1, Point3D P2, Point3D P3, Point3D P4)           calculate angle among three points in 3D space note: calling Point3D.distSquare() is more efficient than calling Point3D.distance().
