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 -
• Polygon -
• Mesh -
• NURBS -
• Bzier -

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

• Rows - Creates horizontal lines.
• Columns - Creates vertical lines.
• Rows & Cols - Both Rows and Columns. Looks like Quads in wire frame display, but all polygons are open (if the primitive type is polygon).
• Triangles - Build the grid with Triangles.
• Quadrilaterals - Generates sides composed of quadrilaterals (default).
• Alternating Triangles - Generates triangles that are opposed; similar to the Triangles option.

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

Center /tx /ty /tz - Location of the tube center from the object origin.

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.

Height /height - The height of the tube.

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

Parameters - Detail Page

Rows / Columns /rows /cols - Number of rows / columns in tube.

U / V Order /orderu /orderv - If a spline surface is selected, it is built at this order for U and 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 - No UV coordinates added to surface.
• Row & Columns - Adds vertex UV coordinates.

Uses / Works in Relation With

Generates tubes from hollow tubes to cones and pyramids.
