geo/PolyWire
Turns the edges of an input into round tubes.
Topology
Reads the input's TOPOLOGY — segment pairs, triangle / quad / hexa polygon edges — and sweeps a circular section along every edge chain, so a wireframe, a curve or a mesh all give a usable tube network. A ball closes the junction wherever three or more edges meet. Each input object gives its own output mesh, and separate curves are never joined end to start. A point cloud, which has no edges, keeps the buffer-order behaviour of a single open polyline.
Parameters
| Name | Type | What it does |
|---|---|---|
| radius | Float | Radius of the swept tube, in world units. |
| segments | UInt32 | Number of sides of the swept circular section. |
| allocator | UInt8 TEMP · POOL · FLAT_POOL | Which allocator backs the scratch buffers: a pool/flat-pool clears at end of cook, temp at end of frame. |
