OdGeSpunSurf Class

Syntax

C++

class OdGeSpunSurf : public OdGeSurface;

Description

A spun surface has a parametric representation of the form: R( u, v ) = Z( u ) + ( C( u ) - Z( u ))cos( v ) + A X ( C( u ) - Z( u ) ) sin( v) where

C(u) is the profile curve
Z(u) is the projection of C(u) onto the spin axis
A is the spin axis direction (unit vector)
C must not be an intersection curve or a trimmed curve

GE_OPERATORS_OVERRIDE_3D
GE_OPERATORS_OVERRIDE_3D	(Inherited from OdGeSurface)
closestPointTo(const OdGePoint3d &, OdGePoint2d , const OdGeUvBox, const OdGeTol &)	This is the overview for the closestPointTo method overload.
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.
getAxis	Returns a vector that represents an axis around which the profile curve is spun to create this spun surface.
getBasePoint	Returns a point that represents a rotational axis origin.
getClosestPointTo	Returns the point on this surface closest to the specified point. (Inherited from OdGeSurface)
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)
getProfile	Returns a pointer to the profile curve that is spun to create this spun surface.
getRef	Returns a vector that indicates the direction of the zero rotation angle of a profile curve.
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)
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)
makeIsoparamCurve(bool, double)	This is the overview for the makeIsoparamCurve method overload.
mirror	Mirrors this entity about the specified plane, and returns a reference to this entity. (Inherited from OdGeEntity3d)
paramOf(const OdGePoint3d&, const OdGeTol&)	This is the overview for the paramOf method overload.
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)
set	Sets the given parameters to this spun surface.
setAngles	Sets angles of rotation of the profile curve of this spun surface.
setEnvelope	Set the rectangle in parameter space that defines the parameter domain of this surface. (Inherited from OdGeSurface)
setRef	Sets a vector that indicates the direction of the zero rotation angle of a profile curve.
transformBy	Applies the 3D transformation matrix to this entity, and returns a reference to this entity. (Inherited from OdGeEntity3d)
translateBy	Applies the 3D translation vector to this entity, and returns a reference to this entity. (Inherited from OdGeEntity3d)
type	Returns the entity type. (Inherited from OdGeEntity3d)
