Houdini 11 Nodes Surface nodes

Creates platonic solids of different types.

Platonic solids are polyhedrons which are convex and have all the vertices and faces of the same type. There are only five such objects, which form the first five choices of this operation.

The Utah Teapot has a long history in Computer Graphics which has led to it being nominated as the sixth Platonic Solid.

Note

The geometry created by this node is not “solid” in the sense of a solid modeler.

Placing Platonic Solids

To...Do this
Place the platonic solid anywhere in the scene

  1. Click the Platonic Solids tool on the Create tab.

  2. Move the cursor into the scene view.

    Note

    You can hold Alt to detach the platonic solid from the construction plane.

  3. Click LMB to place the platonic solid anywhere in the scene view.

    If you press Enter without clicking, Houdini places the platonic solid at the origin.

Place the platonic solid at the origin

Press Ctrl + LMB on the Platonic Solids button on the shelf.

Parameters

Solid Type

What sort of platonic solid to generate.

Orientation

The up direction for the solid.

Radius

How much to scale the default unit sized platonic solid.

Position

The initial location of the solid in space.

The Platonic Solids SOP generates platonic solids of different types. Platonic solids are polyhedrons which are convex and have all the vertices and faces of the same type. There are only five such objects, which form the first five choices of this operation.

This example shows all seven of the different polyhedron forms that can be made using the Platonic Solids SOP.
