Detailed Description

See also
Class NURBSObject, Class NURBSDisplay, Class TessApprox, Class NURBSFuseSurfaceCV, Class NURBSFuseCurveCV, Template Class Tab.

Description:
This class contains a table of NURBSObject entities used to make up the set. Additionally it has two fuse tables: one for fuse curves and one for fuse surfaces. These are used to allow the CVs in the curves or surfaces to be 'stitched' together so if one curve or surface moves the other moves with it. This class also has information required to tessellate the objects to triangle meshes for use in the viewports and the production renderer.

All methods of this class are implemented by the system.
Data Members:
protected:

TessApprox *mpVTess;

This object describes the properties of a tesselation approximation to the mathematical surface for representation in the viewports.

TessApprox *mpRTess;

This object describes the properties of a tesselation approximation to the mathematical surface for the production renderer.

TessApprox *mpRTessDisp;

This object describes the tesselation properties for displacement mapping in the production renderer.

TessApprox *mpVTessCurve;

This object describes the properties of a tesselation approximation to the mathematical curve for representation in the viewports.

TessApprox *mpRTessCurve;

This object describes the properties of a tesselation approximation to the mathematical curve for the production renderer.

float mTessMerge;

Controls the tessellation of surface sub-objects whose edges are joined or very nearly joined. When input to a modifier – such as Mesh Select – requires a mesh, and when NURBS surfaces are tessellated for production rendering, by default 3ds Max adjusts the tessellation of adjoining surfaces to match each other, in terms of the number of faces along the edges. The Merge parameter controls how this is done. If Merge is zero, adjoining faces are unchanged. Increasing the value of Merge increases the distance 3ds Max uses to calculate how edges should match, guaranteeing no gaps between the surfaces when they are rendered.

Tab<NURBSObject*> mObjects;

A table of pointers to the NURBSObjects in the set.

Object *mpObject;

The instantiated object in the scene associated with this NURBSSet. This is NULL if there isn't one.

NURBSDisplay mDisplay;

Controls the display of the object in the viewport..

Tab<NURBSFuseSurfaceCV> mSurfFuse;

A table of objects used to allow surfaces in the set to relate to on another.

Tab<NURBSFuseCurveCV> mCurveFuse;

A table of objects used to allow curves in the set to relate to on another.

Constructor & Destructor Documentation

◆ NURBSSet()

Remarks
Constructor. The data members are initialized as follows:

mpObject = NULL;

mpVTess = NULL;

mpRTess = NULL;

mpRTessDisp = NULL;

mpVTessCurve = NULL;

mpRTessCurve = NULL;

mTessMerge = 0.01f;

mDisplay.mDisplayCurves = TRUE;

mDisplay.mDisplaySurfaces = TRUE;

mDisplay.mDisplayLattices = FALSE;

mDisplay.mDisplayShadedLattice = FALSE;

mDisplay.mDisplaySurfCVLattices = TRUE;

mDisplay.mDisplayCurveCVLattices = TRUE;

mDisplay.mDisplayDependents = TRUE;

mDisplay.mDisplayTrimming = TRUE;

mDisplay.mDegradeOnMove = TRUE;

◆ ~NURBSSet()

virtual DllExport ~NURBSSet ( void  )
virtual
Remarks
Destructor. Any tesselation objects are deleted.

Member Function Documentation

◆ Clean()

DllExport void Clean ( )
Remarks
This removes the NURBS Set connection to a live NURBS object. One use of this is so you can call CreateNURBSObject() twice with the same NURBSSet. You call Clean() in between the calls. Another use is if you want to use the API to copy a NURBS object. You could call GetNURBSSet() followed by a Clea() followed by a CreateNURBSObject().

◆ GetNumObjects()

DllExport int GetNumObjects ( )
Remarks
Returns the number of objects in the set.

◆ SetObject()

DllExport void SetObject ( int  index,
NURBSObject obj 
)
Remarks
This method sets an object in the table of objects maintained by the set. If the index is to an existing object in the set this will replace that object. If it is a new index, all the objects which follow this one in the set are set to NULL and the one passed is set.
Parameters:
int index

If the index is an existing object in the set this will replace the object. If it is a new index, all the objects which follow this one are set to NULL and the one passed is set.

NURBSObject* obj

Points to the object to add to the table.
Remarks
Sets the specified NURBSObject pointer in the table to the specified pointer. If the value of index is greater than the number of items in the table, the table is resized and any non-initialized pointers are set to NULL.
Parameters:
int index

The zero based index of the object to set.

NURBSObject* obj

Points to the object to set.

◆ AppendObject()

DllExport int AppendObject ( NURBSObject obj)
Remarks
Adds the specified object pointer to the end of the table of object pointers.

Note: This method is ONLY used for adding an object to a NURBSSet that is not yet in the scene. To add an object to an existing scene use the global function AddNURBSObjects().
Parameters:
NURBSObject* obj

The pointer to the object to append.
Returns
Returns the number of objects in the table prior to appending.

◆ RemoveObject()

DllExport void RemoveObject ( int  index)
Remarks
Removes the specified object pointer from the table.
Parameters:
int index

The zero based index of the object to remove.

◆ DeleteObjects()

DllExport void DeleteObjects ( )
Remarks
Deletes all the objects that are in the table.

This method frees all the NURBSObjects in a NURBSSet. A developer using a NURBSSet must call this method to free all the memory when done.

◆ GetNURBSObject() [1/2]

DllExport NURBSObject* GetNURBSObject ( int  index)
Remarks
Returns a pointer to the specified object in the table.
Parameters:
int index

The zero based index of the object to return.

◆ GetNURBSObject() [2/2]

DllExport NURBSObject* GetNURBSObject ( NURBSId  id)
Remarks
Returns a pointer to the specified object in the table.
Parameters:
NURBSId id

The Id of the object to return.
