dD_ 32 Posted May 31, 2014 (edited) Hi, i'm working on procedural tree generator in houdini's environment. It's based on space colonisation algorithm, but in next version curve-based pipeline is will be include too, because SCA produces an unpredictable results sometimes.Implemented by Vex, Python and standard nodes.- Correct growth based on colonisation algorisms- Module system for any kinds of vegetation- Fast source and additional modules based only on vex and cvex- Auto correction and smooth for geometrySome days ago i make first demo video: Here i will post some further steps in a workflow, hope for your advices and feedback Edited June 2, 2014 by NmN.Zeke 1 Share this post Link to post Share on other sites
ryew 46 Posted May 31, 2014 Nice work! I'll be curious to hear how you went about doing that, it looks great Share this post Link to post Share on other sites

dD_ 32 Posted June 5, 2014 (edited) So, shrub-demo looks good, but, it has a lot of small and big bugs and they more noticeable in big tree case(next demo will be about growing trees). On some of them I'm currently working now.- non-uniform leaf scatter, it produces overloaded area and defect in small branches- post correction module works good, except that cases, when he try to fix more then 90 degrees turn. When he faces with area like that, he crushes all branch, totally restructuring it. So he work very slow, and make some parts of crown too curly- Shading\lightning, in demo-video, it looks a really bad, in next demo i need good leaf and bark shaders and improved light.- First problem was solved today solution was very simple - use resample sop instead scatter sop. May be in need some tweaks, because we still have overloaded areas, but small brunches look good, you can see it on screen- I spend some time examining a correction module, add one small tweak - now he try to lift up hanging brunches, but i have no a simple solution, so continue to work on.- Improve light setup(using hdri), fix uv on trunk Illustrations: Before tweaksAfter tweaks Edited June 6, 2014 by NmN.Zeke Share this post Link to post Share on other sites
dD_ 32 Posted June 26, 2014 (edited) New step of work and new test render. Rebuild everything, make new leaf shader from scratch and a lot of test and tweaks with sca source setup. Full list of changes and improvements will publicate with a new demo-video. Edited June 26, 2014 by NmN.Zeke Share this post Link to post Share on other sites
dD_ 32 Posted July 11, 2014 (edited) New demo video - creating small tree: Edited July 11, 2014 by NmN.Zeke 1 Share this post Link to post Share on other sites
pelos 6 Posted August 8, 2014 you should show how the otl works, the trees have a nice look =) Share this post Link to post Share on other sites
dD_ 32 Posted December 15, 2014 (edited) New demo, all new features lists in first frame. I'll post sources and setups from demo video in the near future. Edited December 15, 2014 by NmN.Zeke 2 Share this post Link to post Share on other sites
Mandrake0 59 Posted December 15, 2014 nice work.... enjoy the x-mas and don't drink too much vodka we need you next year!!! :-) 1 Share this post Link to post Share on other sites
dulo 12 Posted December 15, 2014 Very nice indeed !! You pan on building an orbolt asset ? Share this post Link to post Share on other sites
dD_ 32 Posted January 2, 2015 I promised, that i will publish some source files and here they are. Inside you can find some network from demovideo, from pre work to render. All assets are unlocked(i used its for git), don't pay attention to that. Happy x-mas. Tree_generator_demoscene_unlocked.hipnc 26 Share this post Link to post Share on other sites
