Class NURBSXFormSurface
See Also: Class NURBSSurface.
class NURBSXFormSurface : public NURBSSurface
Description:
This class is available in release 2.0 and later only.
This class defines a dependent transform (xform) surface. A transform surface is a copy of the original surface with a different position, rotation, or scale. Methods are available to get/set the indices of the parent surface in the NURBSSet and the parent Ids and to specify/retrieve the transformation used on the surface.
All methods of this class are implemented by the system.
Friend Classes:
friend class NURBSSet
Methods:
protected:
Prototype:
void Clean(NURBSIdTab ids);
Remarks:
This method is available in release 3.0 and later only.
This methods breaks the relation between this NURBSObject and a NURBSSet.
Parameters:
NURBSIdTab ids
A table with the IDs of each object in the NURBSSet.
public:
Prototype:
NURBSXFormSurface();
Remarks:
Constructor. The data members are initialized as follows:
mType = kNXFormSurface;
mpObject = NULL;
mpNSet = NULL;
mParentId = 0;
mParentIndex = -1;
mXForm.IdentityMatrix();
Prototype:
virtual ~NURBSXFormSurface();
Remarks:
Destructor.
Prototype:

Remarks:
Sets the index in the NURBSSet of the parent object.
Parameters:
int index

Prototype:
void SetParentId(NURBSId id);
Remarks:
Set the NURBSId of the parent object.
Parameters:
NURBSId id
The Id to set.
Prototype:
int GetParent();
Remarks:
Returns the index in the NURBSSet of the parent object.
Prototype:
NURBSId GetParentId();
Remarks:
Returns the NURBSId of the parent object.
Prototype:
void SetXForm(TimeValue t, Matrix3& mat);
Remarks:
Sets the transformation from the parent surface.
Parameters:
TimeValue t
The time at which to set the transformation.
Matrix3& mat
The transformation to set.
Prototype:
Matrix3& GetXForm(TimeValue t);
Remarks:
Returns the transformation from the parent surface.
Parameters:
TimeValue t
The time at which the transformation is returned.
Operators:

NURBSXFormSurface & operator=(const NURBSXFormSurface& surf);
Remarks:
Assignment operator.
Parameters:
const NURBSXFormSurface& surf
The surface to assign.
