Houdini 21.0 Nodes Geometry nodes

Guide Surface geometry node

Positions points on a triangulated mesh based on guide or fur curves.

On this page
Since 21.0

This SOP positions points of a triangulated mesh along guide or fur curves. The mesh itself is not generated by this node but is expected to be provided on the second input, typically created by the Guide Interpolation Mesh SOP.

By mapping mesh points to curve roots and positioning them anywhere along the curves, this operator enables the creation of surface that follows the flow of guides or fur geometry.

Parameters

Move Mode

Controls how mesh points are positioned relative to their corresponding curves.

Move to Curve

Directly places points on curves at specified parameter locations.

Relative Push along Curve

Offsets points by the difference of each curve parameter location and the curve root.

Transform

Builds a transform from at each curve parameter location, taking into account the orient quaternion attribute.

Location on Curve

Specifies the parameter along the curve where points are positioned.

Use Curve Location Attribute

Enables using a per-point attribute to define each point’s position along its curve.

Curve Location Attribute

Name of the attribute storing per-point curve parameter values.

Normalize Curve Location

Normalizes curve parameter values to a 0–1 range along curve length when enabled.

Index Attribute

Attribute used to associate mesh points with specific guide curves.

Weight Attribute

Attribute specifying the weight of each curve.

Locals

None.
