Whelk is small interactive OpenGL program that generates a cornucopia of shells
horns and many other 3D spiral forms. Exports Wavefront OBJ and POV-Ray mesh2.

Whelk uses various sine-wave deformations that modify the mesh in layers. Each
active layer can use a different waveform and parameters.

Whelk-0-0-3c.exe binary for MS Windows has been tested Windows XP 32-bit and
Windows 7 64 bit.

Before posting this I noticed Shellylib in the POV-Ray utilities section.
Shellylib looks more advanced than Whelk; however, Whelk might do some things
that Shellylib does not do.

Whelk was coded in C++ using the FLTK toolkit and utilizes WildMagic5p13 by
GeometricTools.

It looks promising!

Thank you for your message; whilst the program can generate a variety of
waveforms, it lacks a 'waveform suppressor'. This feature, which is not yet
implemented, targets the waveform over a specific profile range, e.g. from the
zenith to 20 degrees latitude. Implementing this is not that difficult but very
time consuming as far as the UI is concerned. I am currently involved in other
things so this will have to wait until the first beta release. I have no plans
to implement textures at present - something that Shellylib appears to do very
well indeed.

Nicholas.

The waveform suppressor is now implemented in Whelk-0-0-3f and a binary is
available for MS Windows. (32-bit version tested on Windows XP and Windows 7
64-bit).
