New Tuto: creating a forest with only 100 trees

#1

Hi guys, I want to share with you my new tuto: “A forest with one hundred trees. Trees with two dimensions and half”.

You could call this as a “RPC made at home” :wink:

I hope you find it interesting.

Sorry: only in spanish :frowning:

You could use an automatic (and imperfect) translator like THIS.

All the best.

That is absolutely AMAZING! I have been using XP more and more and I love what it can do…it’s things like this that open up even more possibilities in my head. With such an open-ended tool as XP, it’s hard to get your head around what CAN be done, but after seeing this forest, my mind is spinning with ideas!!

Thanks for sharing such useful information and in such wonderful detail!!

Thanks, Cristobal

:wink:

this is a nice piece of work… the effect does reveal itself in certain areas, which make the leaves of trees seem like they are spiraling on the tree, but when that is not happening it does look very reasonable.

Thanks for posting!

You are amazing Cristobal. I wanted to post a question about using QTVR inside EI to acheive “home made RPC”. You just did it. You read my mind?
Great work. Thanks a lot for sharing.

Now XP Gurus and imaginative programmers… We see it can be done. Could you turn this into an “everybody can use” RPC for EI?

Nice work Cristobal…

This is a common technique used in previs circles to help keep the poly count down. In Maya, I typically use particles sprinkled across the terrain floor and those particles are turned into Sprites that constantly face the camera. However, I used a similar techinque to yours in EIAS on an ESPN spot…however, instead of reorienting the trees on the fly to always face camera, I simply took two snapshots per tree and made those billboards intersect each other at 90 degrees. This makes the indivdiual tree look fuller and when combined with a little motion blur, you can get the look of a full tree without the sense of it reorienting to the camera’s position.

As seen here:

And this doesn’t have the benefit of leaves to help hide things.

That’s exactly how we do it, we call them Cruciform “Cruci” Trees.

Nice tute Cristobal! Keep churning 'em out and Happy New Year! :wink:

Another interesting tuto to complement the method:

Lighting flat objects (an application of normal maps and rayDiffuse.

well done! as always, this is a tutorial ‘deluxe’!! :slight_smile:

btw., we used this pseudo-rpc technique successfully for scenes with masses of 2D-clip-people.

cheers
