Wandering at sunset by phresnel Wandering at sunset by phresnel
In the process of implementing trees and forests in picogen (a free terrain synthesizer and renderer) :)

Made using L-Systems + Triangle-Specialized BVH, a generic BVH, and instancing. Texturing is yet missing (but texture coordinate generation is already implemented).

In fact, the feature of trees/forests causes a plethora of new features in picogen 0.4.

Yay.

Looks pretty nice to me. Only thing that bugs me a little is the weird shape of the sun. ^^;
All in all I think you're getting great steps ahead with picogen. :thumbsup:

Thank you very much :hug:

The shape of the sun is a result of the pinhole camera's distortions near the edges. I've integrated a cylindrical mapped camera for the next release of picogen, where there will be less distortion (you could get a feeling for this when you make panoramas with hugin).

It's a pleasure. :huggle:
Oh, I didn't know this, never really did many panoramas, just some simple
ones with my camera and stitched them together in Photoshop or something.

With hugin it is actually really simple. Make some shots with, say, 30% overlap each (if you have time, more :)), and try hugin with it.

Note though that hugin (or better, the underlying tools) sometimes crash. Rule of thumb: Let it do everything automatically. And only if you are not satisfied, begin to tweak parameters (on the other hand, maybe it is only a bad constellation of stars that let it crash on my computer)

Hmm, I tried hugin but never figured it quite out. I guess it seems complicated if one is used to the stich application that comes with Photoshop. ;)

Must admit I never tried that one. Guess you're right :D

Hmm, but I think it's still the same in one thing: it's usually best to use default settings and only tweek things if needed. :nod:

Almost photorealistic

Thank you very much. It is good to get such comments from others, as I am too deep into picogen to validly determine how photorealistic it is :)
