Houdini 20.5 Nodes Geometry nodes

Control geometry node

Creates simple geometry for use as control shapes.

On this page

The Control SOP generates simple primitives as selected by the user. It is primarily used by the Null OBJ to create control shapes.

The Control SOP can take in a single input as its source geometry. It will display the source geometry if the “Custom” control type is selected.

Inputs

Geometry Source

If an input is used, then the source geometry will be displayed as long as the “Custom” control type is selected.

Parameters

Color

Display color.

Size

Size of the control along xyz axes.

Center

Center position of the control.

Rotate

Rotation about the center of the control.

Uniform Scale

Uniform scaling about the xyz axes.

Display

Whether to display only the icon, only the axis, or both.

Icon

Displays only the icon geometry.

Axis

Displays only the axis.

Icon and Axis

Displays both the icon and axis.

Control Type

Switches between the type of geometry to display.

Null

Displays null geometry (i.e. cross).

Circles

Displays circle primitives.

Box

Displays box primitive.

Planes

Displays plane primitives.

Null and Circles

Displays null and circle primitives.

Null and Box

Displays null and box primitives.

Null and Planes

Displays null and plane primitives.

Custom

If an input source is specified, this option will display the geometry of the input.

Orientation

Used in conjunction with circle or plane primitives. Determines which circles or planes to display.

All planes

Displays circle or plane primitives on the YZ, ZX and XY planes.

YZ plane

Displays a circle or plane primitive on the YZ plane.

ZX plane

Displays a circle or plane primitive on the ZX plane.

XY plane

Displays a circle or plane primitive on the XY plane.

YZ, ZX planes

Displays circle or plane primitives on the YZ and ZX planes.

YZ, XY planes

Displays circle or plane primitives on the YZ and XY planes.

ZX, XY planes

Displays circle or plane primitives on the ZX and XY planes.

Shaded Mode

Determines whether to display the primitives as shaded objects or as wireframe objects.

off

Displays primitives in wireframe mode.

on

Displays primitives in shaded mode.

Pack Control Geometry

Use a packed disk primitive for the control geometry. This enables instanced drawing of the control which can greatly improve animation performance.

Extra Snap Points

Allows extra points to be added for snapping, which is especially useful when the control geometry is packed (see Pack Control Geometry, above). Packed geometry will already have a point at its origin, but the points in the packed geometry itself cannot be used as snap targets.
