Dryad Tree Generator

26

dryad_thumb.jpgDryad lets you intuitively create beautiful trees for your virtual world or game.

Dryad was created by the Stanford Virtual Worlds Group, as part of our work on broadening the accessibility of virtual worlds. They write:

In Dryad, you create a tree by visually navigating to it through a design space: the space of all trees. This space has close to a hundred dimensions and Dryad lets you move around it as if it were a city map. To help you find your way, Dryads around the world communicate to share which trees were picked in the past. A collaborative mapping of the tree space emerges, which your Dryad uses to gently steer you towards high-quality finds. We call this collaborative design space exploration.

Dryad currently runs on the Windows and Mac platforms, however, a Linux version will be available

As soon as we finish compiling it. Given how many things we have to statically link, it may be a while.

You can export your tree to Wavefront .OBJ files, which you can import into Blender. For more details, visit the Dryad website.

  1. Agreed Pitel, I usually try these tree generators, just for fun, and Gen3 is actually far better than any other I have tried. Currently downloading this though, coz it does look pretty, we'll see!

  2. Really? When I look at the gen3 page and the script interface images there, they completely scare me off... I mean... Too many settings! As interfaces go, that's pretty much as bad as it gets.

  3. I've used both.

    Dryad is very simple, with good realtime feedback to the changes you make, but the output .obj can be *huge*. Only for non-realtime use.

    There is also the 'community forest' part, which is fun - your creations are uploaded to their server to share - however, the other users contribution can look so weird they are not worth using. If they had 'real' plants as presets it would be better.

    They seem keen to improve it and have sent out surveys to pre-registered users.

    For low poly trees at the moment I much prefer Arbaro ( arbaro.sourceforge.net )

    Sorbus :)

  4. Thanks Bart. I have tried it myself now, it's a nice tool. Though you have the randomizer possibilities it seems that you also can tweak the trees a lot.

    Sorbus, the arbaro project looks impressive, thx for that link!

  5. tryed this last week as it was mentioned on the kerkythea forum.
    nice but needs a heavy machine. Did test out some extreme tree forms too but next time I logged in the tree space couldnt find them back must be the hundered dimensions, lol. my prefered tree maker is onyx not a freebie but it was given away with a mag some time ago.

  6. Well, I tried to download the File for Windows, and I got only a 6KB Zip file which can't be uncompressed. I get a Invalid or damaged file warning each time.

    I can't download anything else from Dryad site...

    Very weird...

  7. First, I really like the "Community forest" idea. Maybe other treegenerators like LSystem or Gen3 are more versatile, but Dryad delivered me faster usable results, and it is very easy to use and the most interactive of all. For me it is the new number one for tree generating, at least for projects with trees in the background and not as main sujet ;)

  8. Wow, that's really rather good! I think we have a new winner... for me at least :]
    Very good realtime feedback!

  9. I got so excited when you said game... until i saw the poly count. there is no decent free tools for making trees suitable for realtime rendering. *downloads speedtree*
