Houdini 13.0 Nodes

interface version 1

Builds the geometric representation of a camera viewing frustrum.

This operator builds a geometry that accurately represents the viewing frustrum of the specified camera.

  • The view frustrum of a camera, generated by this operator. (The near/far clipping plane distances are overridden.)

Parameters

Camera

The camera to build the frustrum geometry for.

Space

See the help page for Camera Plane qL SOP on coordinate spaces.

Near/Far Clipping

Clipping plane settings can be used from the camera (default), or can be overridden here (separately for each plane).

Visual Feedback

If enabled, the output geometry is decorated for visual feedback.

It is still possible to retrieve the regular frustrum geometry, even in this mode. Pressing the Get Boundary Geometry as SOP button will generate a new (Object Merge) SOP that gets the frustrum geometry from within the asset (with all dependencies intact).

Display

Frustrum display options.

Colors, Frustum/Center Color

Apply colors to the results.

Shaded Mode

Allow lighting. (Disabling this will result in constant viewport shading, regardless of any viewport light settings.)

Solid

Use solid (polygonal) geometry for the frustrum sides instead of the default wireframe lines.

Center Scale

Size of the locator that marks the frustum apex (the location of the camera).

Inset

An inset value for Solid frustrum sides.

Get Boundary Geometry as SOP

Creates a SOP (Object Merge) linked to the plain (non-decorated) frustrum geometry. This geometry is a single closed polygonal shell and can be used for procedural work. (The link is “live” of course.)

Dependencies

Uses the following operator(s):
