OdGePlanarEnt Class

Syntax

C++

class OdGePlanarEnt : public OdGeSurface;

GePlanarEnt.h

This class is the base class for all OdGe planes in 3D space.

A parametric point on the plane with parameters u and v maps to the point S(u,v) as follows

S(u,v) = originOfPlanarEntity + (u * uAxis) + (v * vAxis)

uAxis and vAxis need not be either normalized or perpendicular, but they must not be collinear.

The orthonormal canonical coordinate system associated with a plane defined as follows

Parameter	Description	Computed as
origin	Origin of plane.	origin
axis1	A unit vector in the plane.	uAxis.normal()
axis2	A unit vector perpendicular to the plane.	uAxis.crossProduct(vAxis).normal()

The plane equation for a plane is as follows

a * X + b * Y + c * Z + d = 0

Corresponding C++ library: TD_Ge
