Houdini 11 Nodes Surface nodes

Creates a smooth polygonal patch from primitives.

The Polypatch op creates a smooth polygonal patch from a mesh primitive or a set of faces (polygons, NURBS or Bezier curves).

Parameters

Group

Subset of input to use

Spline Type

Cardinal or B-Spline

Connectivity

How to connect the patch together:

Rows

Creates horizontal lines, which are open polygons

Columns

Creates vertical lines, which are open polygons

Rows & Cols

Both rows and columns, all open polygons

Triangles

Build the grid with triangles

Alternating Triangles

Build the grid with alternating triangles

Quadrilaterals

Four-sided quadrilaterals (default)

Inherit from Source

Same connectivity as the mesh source

U Wrap/V Wrap

The wrapping of the built patch

Off

Do not wrap in U/V

On

Wrap in U/V

If prim. does

Wrap in U/V if the input primitive does

U Clamp (First) / U Clamp (Last) / V Clamp (First) / V Clamp (Last)

The clamping of the built patch.

Off

Do not clamp the first/last end in the U/V direction

On

Clamp the first/last end in the U/V direction

If prim. does

Clamp the first/last end in the U/V direction if the input primitive does

Output Divisions

The number of divisions in the output surface. Use more divisions for a smoother surface.

Output Polygons

Force polygonal rather than mesh output

This example demonstrates the use of the PolyPatch SOP to procedurally model complex forms.

Here, a DNA model is created.
