Houdini 13.0 Nodes

interface version 1

Adds simple linear extents at curve end(s).

  • A NURBS curve extented at both ends. (Original curve is also shown for comparison.)

Parameters

Group

A primitive group specification for which curves to be processed.

Start, End
Extend

Amount of extension at each end of the curve.

Units

If enabled, the extent length is measured in scene units. (Otherwise it’s relative to the first/last curve segment length.)

Segments

Segment count multiplier for the extensions (the number being multiplied by the curve degree.)

Extents Only

Generate the extents, but do not join them to the input curves. (When not joined, these are linear polygon segments, regardless of the type(s) of input curve(s).)

Join Extents

Join the extension segments to the original curve(s).

Extension Group Prefix

Creates a primitive group for each newly created extent curve, with the specified prefix (with the defaults the group names will be like extent_0_A, extent_0_B, extent_1_A, etc.)

Works only if the extents are not joined to the original curve(s) (i.e. in Extents Only mode, or with Join Extents turned off.)

To Do

  • Curvature replication (“curly-wurly extend mode”)
