Tree generator preview
« on: January 13, 2011, 04:53:09 pm »

Here are some preliminary screenshots from the new procedural tree generator. The algorithm is based on strands model; there are 20 parameters per branch level that drive the process with a few additional global ones. The tree on the screenshot uses 5 branch levels so it may look as a lot, but the parameters are rather intuitive.

This is a high poly model with 15,000 leaves and 15,000 branches (220,000 faces total), that will be used to generate lower levels of detail.

Currently it uses only a basic shader.







Rendering is very effective so this detail will be available in close views.

O_O O_O O_O
I don't know what to say....
oh yeah... are you going to add a function to smooth out the points at which branches sprout?
But.... just.... O_O wow....

Nice work.  I'd like to see the real-time framerates with a number of trees in the scene.  Are you guys still consistently getting 30 fps?  Or is it still too early?

Can't wait to see the tree generator screens :) *hint*

I think the first word that came to mind was **** but stupendous will have to suffice. Imagine a world the size of a world where no two trees are alike.

Wow!  Procedural trees look great, especially the leaves!  Looks even more amazing close up!

will be used to generate lower levels of detail.

So trees won't look this good close up?  220 000 faces is a ton for one object I guess.

BTW do you think you could post a video of walking around the tree(s)?

I kind of want to see that redwood forest I have been thinking about.

Also I was confused initially when I was on the OT forums and a non-pine tree was shown in a picture. Thank you for not having it generate a pine tree.

I also assume the leaves can have their color and density vary to simulate the change of the fall and bare branches of winter.
I ALSO assume since its generated there could be some sort of growth?

I smell a very cool time lapse of the life and birth of a forest complete with snow for the winter and a very fast day night cycle.

you shouldn't care about number of faces, that is our work :D

Such a video is planned when i finish the LOD system. You will have to wait for it a few days. :)

Cool! Since you've modeled each leaf separately, you can do your fractal magic and make autumn-colors version? Or slightly alter leaf colors like those pine trees? Or maybe even simulate shadowing and darken leaves inside?

great work. would really like to see this in a video in a forest area!!

Edit/
How about movement of wind?

And what about other ground features? bushes grass and rocks? Also experimenting with this?

Wow, I haven't check the forum for a while (yeah, lame I know), but seriuosly this is awesome! Just please make sure this stuff scales nicely, no use having these ultra high detailed trees for situation where you need to have thousands on screen :-)

Damn I need to upgrade my PC when the Demo is out....oh well.

Oh yeah, missed that.   :rolleyes:

Well I look forward to seeing a world full of procedural trees!   :D
