Houdini 13.0 Nodes

Version 0.1.0

Mirrors the shape of a geometry based on topological symmetry, leaving original topology and existing attributes intact.

This operator can be used when simple deleting and mirroring is not an option because of existing assymetric attributes or original point ordering would be lost during the process.

Tip

Use AttribMirror instead of this operator if you want to mirror attributes by positional proximity instead of topologic matching.

Tip

You can mirror attributes on assymetrically shaped but topologically symmetrical geometry with the combination of this operator, AttribMirror, and AttribCopy.

Inputs

Input Geo

The geometry you want to make symmetric.

Reference Geo

The symmetric reference geometry used by the “Reference” mode.

Parameters

Group

Group of points that the operator affects.

Axis

The axis of mirroring.

Opposite

Flips the direction of mirroring to negative side to positive side.

Center

The center of the symmetry.

Mode

The mode of operation.

Match Topology

If the topology of the two sides of the symmetry plane exactly matches, this mode can automatically pair matching points of the two sides.

Reference

If only the shape of the sides and not the topology matches (for example a revolved surface) you have to provide a symmetric version of the geometry to the “Reference Geo” input. This mode will use this reference geometry to pair the points of the sides.

Tracking Points

In “Match Topology” mode, if the sides don’t have enough topologic detail, you may have to provide some hints in the form of paired points to the matching algorithm. This parameter holds the points of one side.

Reference Points

This parameter holds the matching points listed in “Tracking Points” from the other side. The order of the points in the list is important to match.
