  1. Hi! How do I make the global (scene Y) gravity direction for copied l-systems?
  2. Using Lsystem for Cracks

    Hi! I'm trying to create an animated crack effect using the L-system. What I did was project the L-system mesh onto the surface I wish to crack. What should I do next? Is it possible to do the cracks this way?
  3. Grape Modeling

    Hi, I have generated a bunch of grapes using Houdini's L-system SOP. I instanced the grape geometry using the leaf J input for the L-system, and the grapes sometimes intersect each other. As the model has to be used in a dynamic simulation, these intersections will cause issues in future. Is there any way to fix/prevent these geometry intersections?

  4. Tree roots on ground

    Hey guys, I would like some advice on modeling some tree roots on a ground with topology. Attached are my reference and attempts to recreate the geometry in Houdini. Reference: Geo: My .hip: terrain_roots_v02.hipnc I'm not quite satisfied with the way the roots go as it's not quite controllable. Also the Creep SOP kind of displaces the end result from the original points, but I don't know how to make the roots follow the topology of the terrain otherwise.
  5. I'm trying to create a high resolution procedural tree model (without using SpeedTree etc). I looked into L-systems but thats not much use for a more detailed model that is made of one mesh. This is a really interesting tutorial (and has been posted before) - http://www.andyboyd3d.com/siggraph_talk/img27.html But i'm wondering if theres a procedural way to create the branches (seen here - http://www.andyboyd3d.com/siggraph_talk/img32.html). I'm guessing this part was actually done manually but it would be great to have a procedural method! Cheers, Mike
  6. lsystem question

    generations = 2, h = 0.13 Premise: X Rule1: X=F(h)[+F]X Rule2: F(h)=F(h+0.05) Why I get this : F(0.18)[+F(0.05)]F(0)[+F]X Why it is "F(0)"?

  8. L-System Sunflower

    I am struggling with creating correct shape of a sunflower or a Zinnias. how would i translate this to Houdinis L-System? I replicated all signs from the help, but nothing is shown O_o thanks The real goal would be then to have a Zinnias, but there is no L-System command to it, i would have to derive it from the Shape of the SunFlower I have the screenshots from this book: algorithmicbotany.org/papers/abop/abop.pdf thanks!
