FEAview Surface Gallery

Some surfaces whose parametric equations were found in:

  1. "A Modern Differential Geometry of Curves and Surfaces with Mathematica, 2nd ed." Alfred Gray, 1997.
  2. Eric Weisstein's "World of Mathematics" (http://mathworld.wolfram.com/)

Except for the first four surfaces, all of the surfaces below are built using the program's built-in function parser (from http://warp.povusers.org/FunctionParser/). The function parser defines functions from ASCII strings and it frees users from equations that are hard coded into the program.


Klein Bottle. This is produced using a Python script. Python is an easy language to learn and the use of it provides users with additional functionality in defining curves and surfaces.


Klein Bottle 2. This was a surprise. It's the Klein Bottle with the a and b coefficients = 0.

Klein Bottle 3. Another distortion.


Klein Bottle 4. This one has three dimples.

FEAview can tessellate curves, surfaces, and volumes with "elements." (Be they elements from a visualization program like VTK, or finite element analysis elements, or CFD elements, or...)

Using tangent lines to show the speed of different parameterizations, 1X, 2X, and unit-speed.

Monkey Saddle:

File:    /Gallery/monkey_saddle.model

A person could sit in a hyperbolic paraboloid shaped saddle but a monkey would be more comfortable in this surface because there is a place for its tail.
 


Hyperboloid of one sheet:

Hyperboloid of two sheets:

Note: There are two surfaces here; each sheet is treated as a separate surface.

Paraboloids:

On left is alternative definition from functions.constr file.

On right is the definition built into the program.  This is a more versatile function.
