SubDFace Class

True when this component is referenced with the reverse of its natural orientation. This is always false for vertices, and for edges and faces obtained directly from the parent SubD; it is only set on components reached through an oriented reference, such as the face on a given side of an oriented edge.

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.

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.

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.

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

Unique id within the parent SubD for this item

Returns true if the SubD component is damaged.

Returns true if the SubD component is deleted.

Returns true if the SubD component is hidden.

Returns true if the SubD component is highlighted.

Returns true if the SubD component is locked.

Returns true if the SubD component is selected.

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

SubD that this component belongs to

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

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.

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

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

Discards the cached subdivision and surface points for this face, so they are recomputed on next use.

Gets the component index of this face.

Get an edge at a given index

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

Determines whether an object is a SubDComponent referring to the same component, with the same orientation, in the same SubD.

Determines whether this component and another refer to the same component, with the same orientation, in the same SubD.

Gets a hash code for this component.

Gets the Type of the current instance.

Flips ComponentDirection and returns this component, so it can be used inline where an oppositely oriented reference is wanted.

Returns a string of the form "SubDEdge(+12)", naming the component type, the orientation it is referenced with, and its id.

Get a vertex that this face uses by index
