Placing a Torus in the viewer

To...Do this

Place the torus anywhere in the scene

  1. Click the Torus tool on the Create tab.

  2. Move the cursor into the scene view.

    Note

    You can hold Alt to detach the torus from the construction plane.

  3. Click to place the torus anywhere in the scene view.

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

Place the torus at the origin

Press ⌃ Ctrl + on the Torus tool on the shelf.

Torus Handles

There are special handles available at the geometry level for the torus object that allow you to change the radius.

  1. Create a torus object.

  2. Move to the geometry level by double clicking the torus node in the network editor or by clicking the Jump to Operator button on the operation controls toolbar.

  3. Drag the handles to change the radii of the torus.

To...Do this

Change the radius of the hole

Drag the red handle.

Change the radius of the cross section

Drag the green handle.

Parameters

Torus

Primitive Type

Type of geometry to create.

Connectivity

How the surface of the torus is constructed.

Orientation

The plane in which the torus is built.

Radius

First value: The radius of the torus. Second value: The radius of the ring.

Center

Offset of torus center from object origin.

Rotate

Rotation about the center of the torus.

Uniform Scale

Uniform scaling.

Rows

Number of divisions along the swept shape.

Columns

Number of divisions along the cross-section.

Imperfect

Approximates the surface using non-rational points.

Detail

U Order

Order of NURBS/Bezier curve in U direction.

V Order

Order of NURBS/Bezier curve in V direction.

U Angle

The start and end sweep angles of the torus.

V Angle

The start and end angles of the cross-section circle that is swept to make the torus.

U Wrap

Wraps the surface in the U direction.

V Wrap

Wraps the surface in the V direction.

U End Cap

Puts end-caps on the ends of the torus if it is less than 360 degrees.

V End Cap

Applies a face between the top and bottom of the torus, if it is open.
