GeometricObjects Interface CATIForeignSurface

Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.

interface CATIForeignSurface

Interface representing the foreign bi-parameterized geometric elements.

A foreign surface is introduced into CGM by filling the CATIForeignSurface object data with a CATForeignSurfaceData. Then, it is automatically integrated into CGM, and can be used as any CATSurface by the operators and the topology. To create your own surface type, you have to derive the CATForeignSurfaceData class, and re-write the methods that are associated with.
A CATIForeignSurface object is create through the method CATGeoFactory::CreateForeignSurface and deleted with the Remove method.

Methods

o Extrapolate

public virtual Extrapolate(	const	`iRequiredParamExtension`,
		`ioActualExtension`	`= NULL` )

Changes the maximum limitations of this CATIForeignSurface.

Parameters:

iRequiredParamExtension

The value of the extension.

if iRequiredParamExtension.GetX() > 0, Umax is expected to increase by this value,
if iRequiredParamExtension.GetY() < 0 , Vmin is expected to decrease,
if null, no change is required in the related direction.

ioActualExtension

If ioActualExtension is NULL, no information on actual extrapolation is required.

o GetData

public virtual GetData(

)

Retrieves a pointer to the data of this CATIForeignSurface.

Returns:: A pointer to the data. As part of the CATIForeignSurface, it must not be deleted.
