I would like to point out though that it would be even more helpful in the long term if the plug-in was ported to a GEGL operation so that we can use it when GIMP does its processing in linear light 32-bit RGBA.

Re: [Gimp-developer] Where can I help?
Thanks for the info. I have used that filter many times, and I will take a look at what you describe. When light is cast against a 3D mesh, how that light diffuses over the surface can also be affected by whether the ray caster is using "vector normals", or "face normals", and other things. So, triangle size might just be part of the problem.

Gimp has a plug-in called Lighting Effects that simulates the results of shining lights on 3D-deformed images. It is pretty fancy and sometimes gives neat results, but the rendering procedure it uses doesn't work as well as it could, because the triangles that it decomposes the surface into are too small -- you get a lot of faceting effects that a better algorithm would avoid. Plug-ins are more or less freestanding code, so it ought to be possible to improve the rendering without a huge investment of time in learning the whole architecture of Gimp -- but you would learn a substantial amount about the architecture as a side-effect of working on it. -- Bill ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hi Steve, On Tue, Jan 25, 2011 at 09:35, Stephen Greenwalt wrote: > Where can I help? Here's an ultra-short overview of my background: I'm not a developer, but an long term Gimp user. I would suggest: 1. Go into the IRC channel to get direct feedback from the developers. 2. Try to checkout and compile the latest version from the git repository. 3. Have a look into the bugs with the gnome-love keyword: https://bugzilla.gnome.org/buglist.cgi?quicksearch=keywords%3Agnome-love+product%3A%22GIMP%22+ 4. Talk about the bug you are interested in. (IRC or mailinglist) 5. Add a patch to the bugreport. Alternativ you could help with gegl, have a look at this mail: https://lists.xcf.berkeley.edu/lists/gimp-developer/2011-January/026046.html Regards, Tobias ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
