Houdini 13.0 Nodes

interface version 1

Deforms input geometry using a NURBS surface.

An alternative to the Creep SOP, with a slightly different behaviour and parameter set.

  • Deforming a bunch of spikes from the XZ plane onto the surface section of a NURBS torus. (The guide shows the original geometry, as well as the spatial volume that is mapped from XYZ to UVW space.)

Parameters

Envelope, Weight, etc.

Standard-issue qLib deformer framework weighting parameters.

Input Bounds Min, Max

Corners of the 3D spatial box that will be mapped to the UVW space of the NURBS surface. The XZ plane is mapped onto the UV coordinates; Y coordinates are mapped as distance from the surface (height).

Placement Offset, Scale, Pivot

Additional UVW-space placement parameters.

Wrap X/Z

These can “wrap around” the deformed geometry if the surface is closed in the U or V direction.

Moebius Z

A “Moebius-strip” effect is supported along the V direction of the NURBS surface. (The target surface has to be closed in the V or direction – see “Wrap Z”).

Inherit UV Attrib

If enabled, a per-point attribute will be generated for each point, containing its UVW coordinate.
