Tube SOP

Summary

The Tube SOP generates open or closed tubes, cones, or pyramids along the X, Y or Z axes. It outputs as meshes, polygons or simply a tube Primitive.

Parameters - Tube Page

Primitive Type type - ⊞ - Select from the following types. For information on the different types, see the Geometry category articles.

• Primitive prim -

• Polygon poly -

• Mesh mesh -

• NURBS nurbs -

• Bezier bezier -

Connectivity surftype - ⊞ - This option is used to select the type of surface, when using a Mesh Primitive Type.

• Rows rows - Creates horizontal lines.

• Columns cols - Creates vertical lines.

• Rows and Columns rowcol - Both Rows and Columns. Looks like Quads in wire frame display, but all polygons are open (if the primitive type is polygon).

• Triangles triangles - Build the grid with Triangles.

• Quadrilaterals quads - Generates sides composed of quadrilaterals (default).

• Alternating Triangles alttriangles - Generates triangles that are opposed; similar to the Triangles option.

Orientation orient - ⊞ - Primary axis of tube (long axis).

• X Axis x -

• Y Axis y -

• Z Axis z -

Orient Bounds orientbounds - Available only when an input is connected to the Tube SOP to set bounds for the tube. When Orient Bounds = On it will rotate the geometry to match the orientation of the input SOP used for bounds.

Modify Bounds modifybounds - Enabled only when an input is connected to the Tube SOP to set bounds for the tube. Turn Modify Bounds = On to enable the transform parameters below to further modify the position, scale, radius and height of the bounds.

Rotate Order rord - ⊞ -

• Rx Ry Rz xyz -

• Rx Rz Ry xzy -

• Ry Rx Rz yxz -

• Ry Rz Rx yzx -

• Rz Rx Ry zxy -

• Rz Ry Rx zyx -

Center t - ⊞ - Location of the tube center from the object origin.

• X tx -

• Y ty -

• Z tz -

Rotate r - ⊞ -

• Rotate rx -

• Rotate ry -

• Rotate rz -

Radius rad - ⊞ - The first field is the radius of the top of the tube and the second field represents the radius of the bottom of the tube.

• rad1 -

• rad2 -

Height height - The height of the tube.

Anchor U anchoru -

Anchor V anchorv -

Anchor W anchorw -

Imperfect imperfect - This option applies only to Bezier and NURBS types. If selected, the tube is an approximated nonrational curve, otherwise it is a perfect rational curve.

Parameters - Detail Page

Rows rows - Number of rows in tube.

Columns cols - Number of columns in tube.

U Order orderu - If a spline surface is selected, it is built at this order for U.

V Order orderv - If a spline surface is selected, it is built at this order for V.

End Caps cap - If selected, it adds faceted end caps to the ends of the tube.

Texture Coordinates texture - ⊞ - Adds UV texture coordinates to the sphere.

• Off off - No UV coordinates added to surface.

• Row & Columns rowcol - Adds vertex UV coordinates.

Compute Normals normals - Checking this option On will compute surface normals.

Operator Inputs

• Input 0 -

TouchDesigner Build: 2021.100002018.28070before 2018.28070

An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.

A surface type in SOPs including polygon, curve (NURBS and Bezier), patch (NURBS and Bezier) and other shapes like sphere, tube, and metaball. Points and Primitives are part of the Geometry Detail, which is a part of a SOP.

A polygon is a type of Primitive that is formed from a set of Vertices in 3D that are implicitly connected together to form a multi-edge shape.
