OdGePlanarEnt Class

Syntax

C++

class OdGePlanarEnt : public OdGeSurface;

Description

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

Remarks

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

closestPointTo(const OdGePoint3d &, OdGePoint2d , const OdGeUvBox, const OdGeTol &)	This is the overview for the closestPointTo method overload.
closestPointToLinearEnt	Returns the point on this plane that is closest to the specified linear entity, and the point on the linear entity that is closest to this plane.
closestPointToPlanarEnt	Returns the point on this plane that is closest to the specified plane, and the point on the specified plane that is closest to this plane.
copy	Returns a copy of this entity. (Inherited from OdGeEntity3d)
distanceTo	Returns the distance to the point on this curve closest to the specified point. (Inherited from OdGeSurface)
evalPoint(const OdGePoint2d&)	This is the overview for the evalPoint method overload.
get(OdGePoint3d&, OdGePoint3d&, OdGePoint3d&)	This is the overview for the get method overload.
getClosestPointTo	Returns the point on this surface closest to the specified point. (Inherited from OdGeSurface)
getCoefficients	Returns the coefficients of the plane equation for this plane.
getCoordSystem	Returns the orthonormal canonical coordinate system of this plane.
getEnvelope(OdGeInterval&, OdGeInterval&)	This is the overview for the getEnvelope method overload.
getGeomExtents	Returns bounding box of the whole surface or a part of it. The box is axis-aligned in the specified local coordinate system. It is guaranteed to enclose the surface, but not guaranteed to be tight/minimal. (Inherited from OdGeSurface)
getPoles	Finds all poles of surface. Surface envelope not considered. In case of NurbSurface extreme points of envelope are checked. Input arrays may be not empty. In this case new poles will be written to the ends of the arrays. (Inherited from OdGeSurface)
intersectWith	Returns true and the intersection with the specified linear entity, if and only if the specified linear entity intersects with this plane.
isClosedInU	Returns true if and only if this surface is closed in the U direction. (Inherited from OdGeSurface)
isClosedInV	Returns true if and only if this surface is closed in the V direction. (Inherited from OdGeSurface)
isCoplanarTo	Returns true if and only if the specified plane is coplanar with this one.
isEqualTo	Checks whether the specified entity is equal to this one. (Inherited from OdGeEntity3d)
isKindOf	Returns true if and only if this entity is of type (or is derived from) entType. (Inherited from OdGeEntity3d)
isLeftHanded	Checks orientation of the surface. (Inherited from OdGeSurface)
isNormalReversed	Checks normal direction. (Inherited from OdGeSurface)
isOn	Returns true if and only if the specified point is on this entity, as determined by the tolerance. (Inherited from OdGeEntity3d)
isOn	Determines if the passed point is on this surface and retrieves a 2D point that represents parametric values for the passed 3D point if it is on this surface. (Inherited from OdGeSurface)
isOnPlane	Returns true if and only if the specified point is on this plane, regardless of the envelope, as determined by the tolerance.
isParallelTo(const OdGeLinearEnt3d&, const OdGeTol&)	This is the overview for the isParallelTo method overload.
isPerpendicularTo(const OdGeLinearEnt3d&, const OdGeTol&)	This is the overview for the isPerpendicularTo method overload.
makeIsoparamCurve(bool, double)	This is the overview for the makeIsoparamCurve method overload.

normal	Returns the normal to the plane as a unit vector.
paramOf(const OdGePoint3d&, const OdGeTol&)	This is the overview for the paramOf method overload.
pointOnPlane	Returns an arbitrary point on the plane.
project	Projects a point onto this surface in given direction.
project	Projects a point onto this surface. (Inherited from OdGeSurface)
reverseNormal	Reverses the normal of this surface. (Inherited from OdGeSurface)
rotateBy	Rotates this entity by the specified angle about the axis defined by the point and the vector, and returns a reference to this entity. (Inherited from OdGeEntity3d)
scaleBy	Scales this entity by the scale factor about the basepoint, and returns a reference to this entity. (Inherited from OdGeEntity3d)
setEnvelope	Set the rectangle in parameter space that defines the parameter domain of this surface. (Inherited from OdGeSurface)
transformBy	Applies the 3D transformation matrix to this entity, and returns a reference to this entity. (Inherited from OdGeEntity3d)
