SubDFace

SubDFace class

Single face of a SubD

Inheritence: Rhino.Geometry.SubDComponentSubDFace
Derived Classes:

Namespace: Rhino.Geometry
SubDFace: references

Constructors (2)

SubDComponent()

Initializes a new instance of the SubDComponent class

SubDFace()

Initializes a new instance of the SubDFace class

Properties (17)

ControlNetCenterFrame

The face's control net center frame is a plane with normal equal to ControlNetCenterNormal and origin equal to ControlNetCenterPoint. The x and y axes of the frame have no predictable relationship to the face or SubD control net topology.

ControlNetCenterNormal

When the face's control net polygon is planar, the face's control net normal is a unit vector perpendicular to the plane that points outwards. If the control net polygon is not planar, the control net normal is control net normal is a unit vector that is the average of the control polygon's corner normals.

ControlNetCenterPoint

The face's control net center point is the average of the face's vertex control net points. This is the same point as the face's subdivision point.

EdgeCount

Number of edges for this face. Note that EdgeCount is always the same as VertexCount. Two properties are provided simply for clarity.

Id

Unique id within the parent SubD for this item

IsDamaged

Returns True if the SubD component is damaged.

IsDeleted

Returns True if the SubD component is deleted.

IsHidden

Returns True if the SubD component is hidden.

IsHighlighted

Returns True if the SubD component is highlighted.

IsLocked

Returns True if the SubD component is locked.

IsSelected

Returns True if the SubD component is selected.

LimitSurfaceCenterPoint

Get the limit surface point location at the center of the face

ParentSubD

SubD that this component belongs to

PerFaceColor

If per-face color is "Empty", then this face does not have a custom color

SurfaceCenterFrame

Get the limit surface tangent plane at the center of the face. The plane's origin is the point on the limit surface at the center of the face. The plane's z axis is the limit surface normal vector at the center of the face.

SurfaceCenterNormal

Get the limit surface normal vector at the center of the face.

VertexCount

Number of vertices for this face. Note that EdgeCount is always the same as VertexCount. Two properties are provided simply for clarity.

Methods (4)

ComponentIndex()

Gets the component index of this face.

EdgeAt(Int32 index)

Get an edge at a given index

EdgeDirectionMatchesFaceOrientation(Int32 index)

Check if a given edge in this face has the same direction as the face orientation

VertexAt(Int32 index)

Get a vertex that this face uses by index
