the surface of a donut; can also be represented by a flat gluing diagram Above is a doughnut-shaped torus and a torus gluing diagram. They are both intrinsically topologically a torus.
a ring-shaped surface generated by rotating a circle around an axis that does not intersect the circle
a donut like shape, that results from sweeping a small circle ( that has been displaced along X sufficiently ) around the Z axis
a donut-shaped form plus its surrounding fields
a mathematician's name for a donut
a shape that resembles a doughnut or the inner-tube of a tire
a surface or object defined by the rotation of a circle about an axis other than its own
a three-dimensional shape from systems math, the model for many different chaos attractors
a toroid for which the closed plane curve cg is a circle
the mathematical name for a doughnut or ring shape. Technically, this is a quartic shape, but it's so useful that POV-Ray authors created an easy way to define one. ( Language Reference)
Bold, doughnut-shaped molding, sometimes flattened.
Solid geometrical figure with the shape of a doughnut or innertube.
a surface or solid shaped like a doughnut and formed by revolving a circle about a line in its plane that does not intersect it.
A three-dimensional shape that looks like a donut. It's actually a circle that has been rotated around an axis.
In geometry, a torus (pl. tori) is a doughnut-shaped surface of revolution generated by revolving a circle in three dimensional space about an axis coplanar with the circle, which does not touch the circle. Examples of tori include the surfaces of doughnuts and inner tubes. A circle rotated about a chord of the circle is called a torus in some contexts, but this is not a common usage in mathematics.
