Follow-up Comment #2, task #14075 (project administration): Hi Hugh,
Thanks for the comments, and I'll try to answer here. The t_ test/sample files submitted have a routine generating a 3D scalar field from a function which is then scaled to bytes matching a particular RGB-alpha color table: f(x,y,z) with range in [0,255]. Viewing solids generated by function could certainly be a use. I've mostly used this rendering code within time-evolving simulation codes like WRF (Weather Research Forecast model, NCAR), CM1 (Cloud Model 1, G Bryan NCAR), Flash (multiphysics, U Chicago), and various astrophysical and CFD codes. One converts generated floating point scalar and vector fields to bytes before rendering. I can't see including these directly for tests & examples as each can be a trial setting up, and interesting data sets from these tend to be large. There are publicly available data sets from the medical people which can be used and I've checked out, MRI and CAT scans of skulls, frogs, bonsai trees, teacups, and things like that. I have many other sample/test programs which use externally available data, especially so for testing within the AMR codes in paramesh and patch style. There are recipes for incorporating srend within WRF, CM1, and other simulation codes. But, I thought that this submission should be self-contained and modest in size. These other test/sample "t_" programs and recipes could include links to sites where data and application code is freely available. Some are public domain (WRF), others BSD/MIT. But, I view these "t_" sample/test files as trivial because they don't do anything useful besides illustrating use in specific ways. In working with time-evolving simulation application codes and people who write them, I've found such examples helpful. My view is that "public domain" on such template programs invites cut & paste on small pieces, perhaps just the srend calls, then modification without concern. Real applications have their own data arrays, evolution loops, paralellism style, etc. There is some documentation, something I've spent time on and am working on this summer. This is incomplete at the moment and scattered, some here: http://cs.fdltcc.edu/srend/ Some collaborators were interested in SVN vs. git, and I think that consolidating from this current scattered form to one visible clearly free site is a good idea. Many thanks, Ted _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/task/?14075> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
