Mind Thrower Posted June 9, 2017 Share Posted June 9, 2017 Greetings. I can't throw away my idea about creating forest and plants generator. And for this purpose i will use houdini l-system. Yes, this is hard, but other systems usefull only for bushes or some abstract plants, i think. It will be long project. Later will add some progress pictures. 1 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 9, 2017 Author Share Posted June 9, 2017 At first i decided to make spruce or Picea Abies, cause think it is the most complicated tree. Current progress presented in pictures. This is half of work on spruce. Next step will be replace curves in long branch with small branches with needles. 5 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 14, 2017 Author Share Posted June 14, 2017 I have a house in the countryside, and on weekend made some photo. I was very impressed of what i saw. Some refs in attach. 1 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 17, 2017 Author Share Posted June 17, 2017 Little update. Made 300 unique trees on grid with scatter. What is unique - generations, seed and height. Next try to make more flexibility with randomness or almost all elements and pack it in asset with all parameters. 3 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 21, 2017 Author Share Posted June 21, 2017 Took a break from l-system coding and made some grow test. Just for fun =) Rebuilded branch structure, added some angle parameters to needles and the probability of their growth. It's just simple colors captured from viewport. Forgot how to paste video in post body, so here is a link below. If some one knew how to paste it, please wright in reply! https://vimeo.com/222534286 1 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 28, 2017 Author Share Posted June 28, 2017 Rebuilded long branches structure. Added parameters to control length, tropism, angle and random angle of all lateral branches individually, based on growth rules. On picture there is just a quick test on tube, to check how randomness work. All long branches have unique structure based on growth formula with different probabilities of cutting lateral branches. Still a lot of work to do. Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted June 29, 2017 Author Share Posted June 29, 2017 Test of branches with needles connected to simple branching structure. Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted July 4, 2017 Author Share Posted July 4, 2017 Connect small branches to main branch. Need some tune there. Think it is time to work with instances=) One branch is about 1.200K polygons. Optimization will be later on. Made some simple render with lights, but no materials.

stickman Posted July 4, 2017 Share Posted July 4, 2017 Looking very cool. I'd recommend a LOD bake-down cutoff for trees / branches beyond a certain distance to cam, though. Otherwise... madness. 1 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted July 5, 2017 Author Share Posted July 5, 2017 Thanks for advice, stickman. Yeah, I really think about LODs. In the other hand curve rendering with controllable width parameter from ramp can solve problem with polygon count for mid and far planes. Will try different solutions.

Mind Thrower Posted July 7, 2017 Author Share Posted July 7, 2017 Just small update. Add some curvature to branches with needles, to look more naturally. 1 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted August 1, 2017 Author Share Posted August 1, 2017 Made some render test, just place branches with different iteration on top of each other with small offset. Changes - fading needles angle, rebuild branch grow structure. 2 Quote Link to comment Share on other sites More sharing options...
Mind Thrower Posted August 3, 2017 Author Share Posted August 3, 2017 Render full tree for test. Just raw colors. Branches placed by hand. Still need a lot of work to do. Quote Link to comment Share on other sites More sharing options...

Mind Thrower Posted September 3, 2017 Author Share Posted September 3, 2017 Started to make procedural bark texture. Here some tests. 1 Quote Link to comment Share on other sites More sharing options...
stickman Posted September 4, 2017 Share Posted September 4, 2017 nice! Pine like this usually has a shift from reddish to blueish grey somewhere along the trunk. If you're interested, I can dig out a photo I made as reference. 1 Quote Link to comment Share on other sites More sharing options...

The more references, the better will be final product) Later will post my references too and I found that different trees has different colors, think that it is dependent of age of the tree.

stickman Posted September 4, 2017 Share Posted September 4, 2017 can't find it so quickly. Faster to go off and take a photo :-) Will share later Quote Link to comment Share on other sites More sharing options...
