Dryad a new tree generation program

[glen5700]

I just read about this on the Rhino 3D news group and knew you guys would be interested in this. I have not tried it out yet but I will be soon.

Looks like a really interesting approach. The images on their site don't seem particularly realistic but they're all from the internal renderer. Hopefully someone will post here with their results in TG2 so we can see if the models themselves are capable of high quality.

Interesting and free. Thanks for the link. Worth a try at least. I will try and post some examples later on and see how good these trees look.

It was also on Slashdot... I took a look at it earlier today and didn't think the quality was up to snuff for intense TG2 usage.  I hope that I'm wrong, though....

So far so good.  I would put these trees on par with a slightly less optioned Arbaro, but with a better interface.  So far, the trees all imported directly with no problems.  Just needed to tweak the shaders a bit now, as they are super dark.

Thanks for the link!

Thanks for the link, Glen. Personally, it's still going to be a couple of weeks before I even have time for test renders. Worth investigating, though.

Well, the trees are coming out nicely.  However, I am having all hell trying to apply an image map shader to the trunk surface.  Regardless of what I do, a smooth color comes out, like its zoomed in past the point of a pixel.  I've even tried a power fractal at scales down to 0.0001 and though its black and white...it just shows white.  Strange, and chalking it up to a possible bug for now.  Otherwise, these are great for medium distance on out.

Arbaro generated trees had a similar issue - the range of texture coordinates ran from 0.0 to 1.0, regardless of how tall it was.

Try running it through PoseRay and adjusting the texture coordinate scaling in the vertical axis. Can't remember the exact sequence of commands...

Yes, the trees are dark here as well but no matter i am not to impressed with this software but it is free. Overall it is slow to start and slow to edit, even saving as a .obj takes a bit. My file was a whopping 90 megabytes but i had reduced the branch and leaf count as well as the smoothness settings and i managed to get the file size down to 45 megabytes.

It is a simple no-brainer tree maker so i suppose it will be useful to some. Arbaro has more options. Still, the details of my tree turned out nice for a 45 meg obj.

Don't mind the quicky test as it is the first time i ever imported anything into Terragen 2 so i had no idea what i was doing.

Well I'm glad there some hope for it, I have some things to do with the family and then later I will give it a try.

I can't get it to run at all, it keeps telling me that I am missing a Windows dll only not always the same one Video Card drivers?

[moodflow]

Actually, I think this application has serious potential.  It has the detail required for populations, and the file sizes are not bad.  Yes, its slow, but I like the UI better than arbaro (which seems to tank on me half the time).

However, the generated trees require shader work in TG2 to get right, but since I modify all trees I bring into TG2, its no problem.

[dhavalmistry]

yea...can we not take the obje to poseray before we bring it into TG2 and add textures there??....and also, does Dryad write UV info while exporting to obj???

[adit]

Yeah, the program isn't terrible. Here's a small test render I came up with too.

It's unnervingly slow, but if you play around enough you can come up with something cool looking.

[mr-miley]

Hi all. I must admit that its painfully slow, but it seems to work well, as long as you run  it through poseray after export. Below is my effort, only rendered in quick render at 0.25 quality, but I think the software definately has legs.
