Mesh boundary

Creates polyline curves around all mesh boundaries.

Inputs

  • geometry

    • Accepts a single geometry connection (unless the SHIFT key is held).

Outputs

  • geometry

    • Output primitives.

  • points

    • The list of points of the output primitives.

  • points.x

    • The list of x values of the points of the output primitives.

  • points.y

    • The list of y values of the points of the output primitives.

  • points.z

    • The list of z values of the points of the output primitives.

  • boundary mask

    • The list of boolean values identifying if a vertex was used to create a curve or not.

  • boundary indices

    • The list of indices of the vertexes that define the resulting boundary.

Note(s)

  • An example of an instance where a mesh boundary will not be made (and therefore will turn a false result in the boolean mask output) might be where mesh edges/boundaries are welded together (and thus not a boundary) or, a primitive type other than a PolyMesh is input into this node.

  • Other names for this node include: MeshBoundary, Edges, Contour, and Border.
