Some fun things to play with, of possible interest to some of the J community:
http://www.openvsp.org/ This is a parametric geometry design tool. "VSP" stands for "Vehicle Sketch Pad". Supplied binaries are only for windowsan mac, but the source is at https://github.com/OpenVSP/OpenVSP/. I've not tried building it on openbsd (or, linux) yet. It might also be fun to create J bindings for so of the libraries it uses? I think J should be a natural for playing with the math involved, but getting at the data is currently more tedious than it should be. It might also be worth implementing some J support for some of its file formats. I don't think we have any of these supported yet (tell me if I am wrong?): *.fel Felisa file, *.hrm Cross Section (XSec) file, *.stl Sterolith file, *.3dm Rhino3D file, bodyin.dat NASCART file, *.plt TecPlot file or STecPlot file and, *.pov Persistence of Vision Raytracer -------------------------------- http://www.xflr5.com/xflr5.htm This is something of a virtual wind tunnel, so it goes well with openvsp. See also http://sourceforge.net/projects/xflr5/ (Windows binary, compilation supported on windows, mac and linux.) I've not taken the time yet to play with this, it looks fun - but anything worth doing takes time.
