SubD Methods |
The SubD type exposes the following members.
Name | Description | |
---|---|---|
ClearEvaluationCache |
Clear all cached evaluation information (meshes, surface points, bounding boxes, ...)
that depends on edge tags, vertex tags, and the location of vertex control points.
| |
ComponentFromComponentIndex |
Returns a SubDComponent, either a SubDEdge, SubDFace, or SubDVertex, from a component index.
| |
ComponentIndex |
If this piece of geometry is a component in something larger, like a BrepEdge
in a Brep, then this function returns the component index.
(Inherited from GeometryBase.) | |
ConstructConstObject |
Assigns a parent object and a sub-object index to this.
(Inherited from CommonObject.) | |
CopyEvaluationCache |
Expert function that copies cached evaluations of component subdivision points and
limit surface information from src to this. Typically this is done for performance
critical situations like control point editing:
- Copy a SubD to be modified (this does not copy the evaluation cache)
- Copy the evaluation cache from the unmodified SubD
- Modify the SubD copy
- Update the surface mesh cache so that only the modified parts are recalculated
- Display, meshing, bounding boxes on the modified SubD are now available
| |
CreateFromCylinder |
Creates a SubD form of a cylinder.
| |
CreateFromLoft |
Creates a SubD lofted through shape curves.
| |
CreateFromMesh(Mesh) |
Create a new SubD from a mesh.
| |
CreateFromMesh(Mesh, SubDCreationOptions) |
Create a new SubD from a mesh.
| |
CreateFromSurface |
Create a SubD that approximates the surface. If the surface is a SubD
friendly NURBS surface and withCorners is true, then the SubD and input
surface will have the same geometry.
| |
CreateFromSweep(NurbsCurve, NurbsCurve, IEnumerableNurbsCurve, Boolean, Boolean) |
Fits a SubD through a series of profile curves that define the SubD cross-sections and two curves that defines SubD edges.
| |
CreateFromSweep(NurbsCurve, IEnumerableNurbsCurve, Boolean, Boolean, Boolean, Vector3d) |
Fits a SubD through a series of profile curves that define the SubD cross-sections and one curve that defines a SubD edge.
| |
CreateGlobeSphere |
Creates a SubD sphere made from polar triangle fans and bands of quads.
The result resembles a globe with triangle fans at the poles and the
edges forming latitude parallels and longitude meridians.
| |
CreateIcosahedron |
Creates a SubD sphere based on an icosohedron (20 triangular faces and 5 valent vertices).
This is a goofy topology for a Catmull-Clark subdivision surface
(all triangles, all vertices have 5 edges).
You may want to consider using the much behaved result from
CreateSubDQuadSphere(sphere, vertexLocation, 1)
or even the result from CreateSubDGlobeSphere().
| |
CreateQuadSphere |
Creates a SubD sphere made from quad faces.
| |
CreateTriSphere |
Creates a SubD sphere made from triangular faces.
This is a goofy topology for a Catmull-Clark subdivision surface
(all triangles and all vertices have 5 or 6 edges).
You may want to consider using the much behaved result from
CreateSubDQuadSphere() or even the result from CreateSubDGlobeSphere().
| |
DataCRC |
Returns a CRC calculated from the information that defines the object.
This CRC can be used as a quick way to see if two objects are not identical.

Dispose |
Actively reclaims unmanaged resources that this instance uses.
(Inherited from CommonObject.) | |
Dispose(Boolean) |
Deletes the underlying native pointer during a Dispose call or GC collection
(Overrides GeometryBaseDispose(Boolean).) | |
Duplicate |
Constructs a deep (full) copy of this object.
(Inherited from GeometryBase.) | |
DuplicateEdgeCurves |
Gets Nurbs form of all edges in this SubD, with clamped knots.
NB: Does not update the SubD evaluation cache before getting the edges.
| |
DuplicateEdgeCurves(Boolean, Boolean, Boolean, Boolean, Boolean, Boolean) |
Gets Nurbs form of edges in this SubD.
NB: Does not update the SubD evaluation cache before getting the edges.
| |
DuplicateShallow |
Constructs a light copy of this object. By "light", it is meant that the same
underlying data is used until something is done to attempt to change it. For example,
you could have a shallow copy of a very heavy mesh object and the same underlying
data will be used when doing things like inspecting the number of faces on the mesh.
If you modify the location of one of the mesh vertices, the shallow copy will create
a full duplicate of the underlying mesh data and the shallow copy will become a
deep copy.
(Inherited from GeometryBase.) | |

completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can
call this function as many times as you want.

to being an independent instance.

you may want to call Flip() on a Brep after transforming it.
