Torus

A torus is a 3D shape formed by a small circle that rotates around a bigger circle. It usually looks like a circular ring, or a donut.

(A) Default torus (smooth)

(B) Torus with 180-degree Horizontal Circumference

(C) Torus with the Smooth property set to false

(D) Torus with 180-degree Vertical Circumference

You can customize the shape of a torus with these shape-specific properties:

Property:	Description:
Rows	Set the complexity of the Mesh, together with the Columns value. You can enter a value from 3 to 64. The higher the value, the smoother the shape, but at the cost of more polygons to calculate. The default value is 16.
Columns	Set the complexity of the Mesh, together with the Rows value. You can enter a value from 3 to 64. The higher the value, the smoother the shape, but at the cost of more polygons (and therefore more computation). The default value is 24.
Tube Radius	Set the radius of the tube itself in meters. The default value is 0.1.
Horizontal Circumference	Set the degree of the torus's circumference. For example, if you set this value to 180 (as the (B) image above demonstrates), it looks like someone cut half of the torus away (like leaving half of a donut). The default value is 360 (full torus).
Vertical Circumference	Set the degree of the tube's circumference. For example, if you set this value to 180 (as the (D) image demonstrates), it looks like a half-pipe. The default value is 360 (full tube).
Smooth	Enable this option to smooth the edges of the polygons. This property is enabled by default.
