Torus
A Torus in its most elementary form is a doughnut-shaped object. COOL 3D provides
versatile options for tweaking it to become an object most unlike an ordinary doughnut.
In addition to being a circular or curved object, a torus can be a regularly shaped
polygon, and its side curvature can be faceted to create polygonal shapes through its
cross-section.
To create and tweak a torus:
1 Select Torus from the Object Menu.
2 Adjust the following settings in the
Geometric Toolbar:
• Radius Determines the size of the
opening in the center of the torus.
• Thickness The radius of the torus
through its cross-section.
• Sides The number of sides of the torus
as a polygon. It can have from three
(triangular torus) up to 30 sides (virtual
circle). The greater the number of sides,
the rounder the torus becomes.
New Objects
Single Cone
The Single Cone is a basic cone with a flat,
circular base. Textures, colors and lighting
effects can be applied separately to the base
and to the curved surface.
Frustum
The Frustum is a truncated square-based
pyramid. Tweaking its dimensions can result
in an object that closely approximates a
pyramid, a cube, or a rectangular prism of
virtually any proportions. Each face of the
frustum can be individually selected to apply
color, lighting and texture effects.
