3D model description

This is an easy to use 3D surface plotter. Use the Customizer to change the function plotted and the range.

To use in your own code, call graphFunction3D(function,minX,minY,maxX,maxY) where the function is a string such as "exp(-x^2-y^2)" (for more details, see here). By default a surface of smallish thickness is drawn. Here are some options:

  • surfaceThickness=dz: change the thickness of the surface
  • flatMinimumThickness=dz: does a flat-bottomed graph; dz specifies the minimum thickness (set to 0 for an automatic smallish thickness)
  • bottomFunction=f: specifies a function for the bottom of the graph

There are also makePointList() and makeFaceList() functions that generate the arguments for a polyhedron().

This demonstrates and uses my function parser. The standalone version bundles the parser.

Update: May 17, 2017: Rewrote to generate whole polyhedron at once and to use my own code. :-)
