FEAview Surfaces of Revolution Gallery

The surfaces below are parametric surfaces of revolution and rotational sweeps generated by FEAview. All of the surfaces have a corresponding modeling file that can be read by FEAview.

Note:  For parametric surfaces of revolution, specify an odd number of stacks if you wish the figure to be symmetrical about its equator.

Epicyloid of Revolution:

File:    /Gallery/epicyloid_of_revolution.model

In the animation produced by using the "a", "b", and "c" spin-buttons, in the Edit Curve Dialog, the epicyloid (the curve in the center) produces some amazing patterns.  Not to be out-done, the epicyloid surface of revolution acts like a sausage extruder when the spin-buttons are used in the Edit Surface Dialog.

 


Hypocycloid of Revolution:

This may another breakdown of the "standard parameterization" of a surface of revolution. On close inspection, the surface looks much more complicated than the curve that produced it.
 


Limaçon of Revolution:

File:    /Gallery/limacon_of_revolution.model

The figure on the bottom is a surface of revolution from a limaçon using the standard parameterization formula. This may be an error or a limitation of the formula; the interior of the surface doesn't reflect the loop in the limaçon curve.

The rotational sweep function, that produced the figure on the top, does it right.

Rotational Sweep:

The rotational sweep is a more dependable modeling function than the standard equation of a surface of revolution from Calculus.
