Detailed Description

Fillet surface with variable radius is normal or with preservation of edges.

Fillet surface with variable radius is NURBS-surface constructed on three curves: curve1, curve0, curve2. The first surface parameter coincides with the parameter of curve1, curve0, curve2 curves. The second parameter is changed from zero (points coincide with curve1) to unit (points coincide with curve2). Function "function" determines the change of the radius and equals the ratio of the current radius to given for surface. The parameter of radius function coincides with the parameter of curves curve1, curve0, curve2. If coefficient of shape conic = ARC ( 0 ), then the weight of each point of the curve0 curve determined by the function weights0 and calculated so that the section of surface along its second parameter is a circular arc i.e. for any parameter u three points of curve1(u), curve0(u), curve2(u) determine the NURBS-curve with the shape of a circular arc. If coefficient of shape conic != ARC, then the weight of each point of the curve0 curve is equal to conic / ( 1.0 - conic ). If conic = 0.5, then the surface section along its second parameter is parabola.

◆ Duplicate()

MbSpaceItem& MbChannelSurface::Duplicate ( MbRegDuplicate * iReg = nullptr ) const

overridevirtual

Create a copy of the object.

Create a copy of an object using the registrator. Registrator is used to prevent multiple copy of the object. If the object contains references to the other objects, then nested objects are copied as well. It is allowed not to pass registrator into the function. Then new copy of object will be created. While copying of single object or set of not connected objects, it is allowed not to use registrator. Registrator should be used if it is required to copy several connected objects. It is possible, that objects connection is based on the references to common objects. Then, while copying without using of registrator, it is possible to obtain set of copies, that contain references to the different copies of the same nested object, that leads to loss of connection between copies.

Parameters
