Welcome to the wonderful world of NXplot3d v3.0. Before you go off and start using the program there is one important step that needs to be done manually. One of the features of NXplot3d requires use of a custom renderman shader. This shader is called contour.slo, and is part of the NXplot3d.app directory. You need to opy this file to either /LocalLibrary/Shaders (preferred location) or $HOME/Library/Shaders. If you don't do this, the 'contour surf' option will not function.
This version has nearly 2 pages of improvements and bug fixes. I encourage you to look at the 'history' entry in the online help to see what has changed. Additionally there is a sample archive with demo plots and animations available at ion.rice.edu. This archive includes a file with instructions for producing the example plots. It would be worth your time to download this and see what the program can do. This version was designed specifically for color machines. The results won't look nearly as impressive on a greyscale machine.
This version was compiled under NeXTStep 3.2. It should run under 3.1, and you should be able to recompile it for use under 3.0 (the binary distribution is FAT). Full source is available as a separate archive.
The only reimbursement I ask for using this program is that you cite the program in the bibliography or credits of any publications, presentations or posters you prepare using this program. Also, I enjoy hearing how much you like/hate various features, so if you have something positive or negative to say, let me know!
