SubD Class

Create a new instance of SubD geometry

Protected constructor used in serialization.

Indicates if this object has been disposed or the document it originally belonged to has been disposed.

All edges in this SubD

Get a new, empty SubD object.

All faces in this SubD

Returns true if the Brep.TryConvertBrep function will be successful for this object

Gets true if this class has any custom information attached to it through UserData.

true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.

If true this object may not be modified. Any properties or functions that attempt to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.

Test SubD to see if the active level is a solid. A "solid" is a closed oriented manifold, or a closed oriented manifold.

Tests an object to see if it is valid.

Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

List of custom information that is attached to this class.

Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use shareable set of information.

Gets the amount of user strings.

All vertices in this SubD

Clear all cached evaluation information (meshes, surface points, bounding boxes, ...) that depends on edge tags, vertex tags, and the location of vertex control points.

Returns a SubDComponent, either a SubDEdge, SubDFace, or SubDVertex, from a component index.

If this piece of geometry is a component in something larger, like a BrepEdge in a Brep, then this function returns the component index.

Assigns a parent object and a sub-object index to this.

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

Creates a SubD form of a cylinder.

Creates a SubD lofted through shape curves.

Create a new SubD from a mesh.

Create a new SubD from a mesh.

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.

Fits a SubD through a series of profile curves that define the SubD cross-sections and two curves that defines SubD edges.

Fits a SubD through a series of profile curves that define the SubD cross-sections and one curve that defines a SubD edge.

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.

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().

Creates a SubD sphere made from quad faces.

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().

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.

Actively reclaims unmanaged resources that this instance uses.

Deletes the underlying native pointer during a Dispose call or GC collection

Constructs a deep (full) copy of this object.

Gets Nurbs form of all edges in this SubD, with clamped knots. NB: Does not update the SubD evaluation cache before getting the edges.

Gets Nurbs form of edges in this SubD. NB: Does not update the SubD evaluation cache before getting the edges.

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.

If you want to keep a copy of this class around by holding onto it in a variable after a command 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.

Determines whether the specified object is equal to the current object.

Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().

Reverses the orientation of all SubD normals.

Bounding box solver. Gets the world axis aligned bounding box for the geometry.

Aligned Bounding box solver. Gets the plane aligned bounding box.

Aligned Bounding box solver. Gets the world axis aligned bounding box for the transformed geometry.

Aligned Bounding box solver. Gets the plane aligned bounding box.

Serves as the default hash function.

Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.

Gets the Type of the current instance.

Gets user string from this geometry.

Gets a copy of all (user key string, user value string) pairs attached to this geometry.

Modifies the SubD so that the SubD vertex limit surface points are equal to surface_points[]

Modifies the SubD so that the SubD vertex limit surface points of the listed vertices are equal to surface_points[].

Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.

Joins an enumeration of SubDs to form as few as possible resulting SubDs. There may be more than one SubD in the result array.

Joins an enumeration of SubDs to form as few as possible resulting SubDs. There may be more than one SubD in the result array.

If possible, converts the object into a form that can be accurately modified with "squishy" transformations like projections, shears, an non-uniform scaling.

Creates a shallow copy of the current Object.

Computes an estimate of the number of bytes that this object is using in memory.

Merges adjacent coplanar faces into single faces.

Merges adjacent coplanar faces into single faces.

Destroy cache handle

Makes a new SubD with vertices offset at distance in the direction of the control net vertex normals. Optionally, based on the value of solidify, adds the input SubD and a ribbon of faces along any naked edges.

Called when this object switches from being considered "owned by the document" to being an independent instance.

Resets the SubD to the default face packing if adding creases or deleting faces breaks the quad grids. It does not change the topology or geometry of the SubD. SubD face packs always stop at creases.

Rotates the object about the specified axis. A positive rotation angle results in a counter-clockwise rotation about the axis (right hand rule).

Scales the object by the specified factor. The scale is centered at the origin.

Attach a user string (key,value combination) to this geometry.

Set the location of a single vertex surface point. This function is not suitable for setting the locations of multiple vertex surface points that are topologically near to each other.

Apply the Catmull-Clark subdivision algorithm and save the results in this SubD.

Apply the Catmull-Clark subdivision algorithm and save the results in this SubD.

Checks that a surface mesh evaluation cache exists, and that it has the required options. This cache is used by - SurfacePoint, - ToNurbsCurve(Boolean), and - CreateFromSubD(SubD, Int32).

Create a Brep based on this SubD geometry, based on SubDToBrepOptions.Default options.

Create a Brep based on this SubD geometry.

Create a JSON string representation of this object

Returns a string that represents the current object.

Transforms the geometry. If the input Transform has a SimilarityType of OrientationReversing, you may want to consider flipping the transformed geometry after calling this function when it makes sense. For example, you may want to call Flip() on a Brep after transforming it.

Transforms an enumerable of SubD components.

Translates the object along the specified vector.

Translates the object along the specified vector.

Updates vertex tag, edge tag, and edge coefficient values on the active level. After completing custom editing operations that modify the topology of the SubD control net or changing values of vertex or edge tags, the tag and sector coefficients information on nearby components in the edited areas need to be updated.

Updates limit surface information returned by - SurfacePoint, - ToNurbsCurve(Boolean), and - CreateFromSubD(SubD, Int32). The density of the mesh cache is Default.
