Hi Brian,
just a small update... I wanted to make a NURBS surface and noodled a lot with some solutions, which were not satisfactory, until i downloaded today a Trial of ZBRush... I think i need to buy me a copy of ZBrush in the future due to it's fantastic ZRemesher, for example. Simply amazing, imho. After that i converted with Fusion360 T-Splines.
I attach the files, both quad mesh and NURBS model.
Best regards
Stefan

Thank you Stefan for the excellent information.
I think I will try for a Nurbs Costa surface script this winter, LOL.
Gang or Elliptic may have Weierstrass code.
There is also the L. Baker book with some old C code...
I'm not sure how the math works.
There are also higher Genus Costa surfaces, with 2+ holes.

Hi Brian,
a script would be interesting. Wish i could program. Would help me often in some scenarios.

Found some code for Weierstrass functions in C++11

I wonder if this library could be "Included" or linked to in a MoI script?
- Brian
Besides a possible Costa surface script, the functions could be used for other projects.

Hi Brian,
re:

Hmmm, well the only method that I can think of for that would be to compile the library into its own standalone executable program. A script in MoI could then run the program and pass command line parameters to it and receive any output that the program wrote to stdout.
That can be done by the moi.filesystem.shellExecute method, which as of the Sep-10 v4 beta has a "wait for finished" option in it:
quote:
moi.filesystem.shellExecute(), added wait for finished parameter.
moi.filesystem.shellExecute( path, params, wait ) now takes an optional 3rd boolean parameter for whether to wait until the called process has exited before returning. When used, the return value from shellExecute() is an object containing an .exitCode property for the integer exit code of the called process and an .output string parameter for any text written by the called process to stdout.
Example:
var res = moi.filesystem.shellExecute( 'cmd /c dir c:\\', '', true );
if ( res.output ) moi.ui.alert( res.output );
