Summary

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

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 -

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 -

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.

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.
