Cylinders Are Useful

Node

Description

Three colored cylinders with differing height and radius.

VRIGNETTE Notes

You can create cylinders of any radius or length but to make a cylinder that bends, such as a curved pipe, requires either an Extrusion with a circular cross-section or a mesh (compound set of objects).

Example

Rotate the vrignette to view the geometry.
