Houdini 12 Nodes Surface nodes

Duplicates and mirrors geometry across a mirror plane.

The Mirror Operation duplicates and mirrors geometry. If the point normal attribute exists, it is also mirrored for each point. Quadrics and pasted surfaces are also supported.

Using Mirror

At the Scene level

  1. Select the object(s) you want to mirror.

  2. Click the Mirror tool on the Modify tab.

  3. Select a plane in which to mirror the object from the drop-down menu on the operation controls toolbar.

At the Geometry level

  1. Select the curves and/or surfaces you want to mirror.

  2. Click the Mirror tool on the Modify tab.

  3. Use the handles to move and rotate the symmetry plane.

Parameters

Group

Primitives to mirror

Origin

Origin of mirror plane

Distance

Distance of mirror plane along its normal

Direction

Normal direction of mirror plane

Reverse Normals

Reverses the normals of the mirrored geometry. Reverse U and Reverse V options apply only to mesh-type primitives (such as NURBS surfaces for example).

Keep Original

Preserves the input geometry. If unchecked, only the selected geometry will remain.

Consolidate Seam

Consolidates points along the mirror. New points are only consolidated with their mirrored counterpart.
