3D function plotter for Customizer / OpenSCAD

cults3d

This is a straightforward 3D surface plotter that's easy to use. Simply customize it by changing the function plotted and its range using the Customizer. To integrate this into your code, call graphFunction3D with these parameters: function, minX, minY, maxX, maxY. The function parameter should be a string like "exp(-x^2-y^2)" (for more details, check here). By default, it draws a surface of moderate thickness. You can customize it further with the following options: * Change the surface thickness by setting dz. * Use flatMinimumThickness=dz to create a flat-bottomed graph; set dz to 0 for an automatic smallish thickness. * Specify a function for the bottom of the graph using bottomFunction=f. Additionally, you have access to makePointList() and makeFaceList(), which generate the arguments for a polyhedron() function. This plotter also demonstrates my function parser. The standalone version bundles the parser together. Update: May 17, 2017 - I rewrote this to generate the whole polyhedron at once and used my own code instead of relying on external functions.
