View Full Version : What is the best way of reconstructing scene
04-07-2006, 07:05 PM
I have a question about turning 2D matte paintings of photos into 3d.
I have done something, but I think I reconstruct the scene rather clumsy.
How do you do it?
I think there is a better way to do it.
post a few pictures of your attempt, or better yet a scene file, anything really, so people can understand WHAT you tried to do.

well, i didn't think anything specific...
I just wanted to now, how you guys are doing this...
Actualy I can post a scene file of a tower. I tried to match the geometry to the matte painting and I have been having issues of proper perspective and so on... I thing i don't have so much control about it...
I'm not good at modelling I rather play with the scene and lighting and so on:D.
So here you go... the scene file HERE: http://sweb.cz/Animos_PC/images/Tvorba/vez_final_net.jpg (http://kutkin.wz.cz/tower.zip)
Your zip file might be corrupted, when I tried to unzip it, stuffit crashed. Never happened before.

works fine for me...
so try this:
you can use this image for the projection:http://sweb.cz/Animos_PC/images/Tvorba/vez_final_net.jpg (http://sweb.cz/Animos_PC/images/Tvorba/vez_final_net.jpg)
Hope it works

Presuming that you have the meta information on the camera, lens, apeture, fov, etc, then these numbers can be plugged into the camera in your 3d package. I only remember C4d 7 years ago, but it all should be there for you. If not, then you'll have to adjust them yourself (which isn't a lot of fun, but do-able). Of course, you can distort the actual geometry of your scene to match stuff up, dependant on your shots, or how much you can take over the plate.
I recommend having a look at Rectilinear Panorama (http://www.altostorm.com) which does a good job at correcting perspective distortions.
I'd also suggest starting out with something easy, like blocks on a table, to get the workflow of camera mapping, then broaden out from there.
It's important to remember to keep your geometry as simple as possible at first, and use flats where you can. Take a look at deak ferrand's work (http://www.hatchfx.com) at Hatch, and you'll see some wonderful setups, with a lot of simplicity in the 3d.
Wow, those bigsky links are amazing :-).
Kutkin: I looked at your stuff, I don't see anything wrong with it technically what look are you trying to get at really?
I do agree, keep the geometry a bit simpler.

What I am having problem with is "how to reconstruct scene correctly due to perspective and all other stuff"
For example I am having troubles with the perspective of the wall...
It could be maybe fixed by using painted perspective grids.
And as I said, I think it is all a bit uncontrolled...
How do you reconstruct scene in the VFX shot?
