Torus SOP

Summary

The Torus SOP generates complete or specific sections of torus shapes (like a doughnut).

torusSOP_Class

Parameters - Torus Page

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

• 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 - ⊞ - The axis along which the torus is constructed.

• X Axis x -

• Y Axis y -

• Z Axis z -

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

Radius rad - ⊞ - The first value (radx) defines the radius of the torus, the second value (rady) determines the radius of the inner ring.

• X radx -

• Y rady -

Center t - ⊞ - Offset of torus center from object origin.

• X tx -

• Y ty -

• Z tz -

Rows rows - The rows define the number of divisions along the torus.

Columns cols - The columns determine the number of divisions along the torus' cross-section.

Parameters - Detail Page

Angle Offset angleoffset -

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.

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

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

U Angle angleu - ⊞ - The start and end sweep angles of the torus, if U Wrap is not enabled.

• beginangleu -

• endangleu -

V Angle anglev - ⊞ - These are the start and end angles of the cross-section circle that is swept to make the torus, if V Wrap is not enabled.

• beginanglev -

• endanglev -

U Wrap closeu - If U Wrap is checked, it creates a 360 cross-section.

V Wrap closev - Checking V Wrap creates a torus along V by closing the primitive.

U End Caps capu - If U End Caps is checked, it puts faceted end-caps on the ends of the torus if it is less than 360.

For more capping options, turn this parameter off, and append a Cap SOP.

V End Caps capv - If V End Caps is checked, it applies a face between the top and bottom of the torus - if the torus is open.

For more capping options, turn this parameter off, and append a Cap SOP.

Texture Coordinates texture - ⊞ - This adds uv coordinates to the geometry created by the Torus SOP.

• Off off - No uv coordinates added.

• Row & Columns rowcol - uv coordinates added based on Rows and Columns in the geometry.

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

Operator Inputs

• Input 0 -
