3D animation (with glasses)

Did anyone ever do something like this; making an animation which can be viewed through 3D glasses for that incredible 3D experience? The museum would like to try something like this, but I don't know if I can handle it.

Of course never tried this. But I would start by looking for 2 cameras
Calculating the right both positions to simulate eyes positions.
Then deciding what is viewed by any of each eye.
I guess there are some tutorials on web describing the first steps.

But another great idea. Hope you'll try something in 3D

I thought that DocCharly65, was doing stuff like that all the time and posting? Maybe not animation?
It has been eaten.

The camera in TG3 Professional has stereo options to automatically calculate left and right eye views, so you only need to animate one camera.

Just because milk is white doesn't mean that clouds are made of milk.

I haven't actually looked into it yet, but thanks for mentioning the double cam, Matt. That sure makes a difference!

Sorry - I'm late but I saw the topic just now...

I thought about doing my "plan" in 3D. But such wishes I must shift to a far, far later time.

It is not really complicated with TG3 but it needs the double rendertime of course. 3 or 4 CPU-generations later I think about it again...  ;)

I have no experience yet if it's better to keep 2 directories with separated right or left frames or convert each two frames R/L to one 3D-frame and then stich the movie.

Another thing:
In my 3D pics I had the problem that there are little differences in the rendered terrain between left and right frame (strangely enough not the objects). These differences feel like flickering in your eyes and make you tired if you look an animation. some people even get headache.

Also it must be considered that with moving camera and focus the Zero par. point must be moved as well. I could not calculate this - I would have to try and check the render results.

I'm sure there are many specialists on the world... unfortunately I don't know any  :-\

In summary:
It is entirely possible, but needs intensive research.

...perhaps after 2020 ??  ;)

Mmmm, you're making my life a little less enjoyable, Nils :( Thanks for your input nonetheless; every bit of info is very welcome. I might not want to do this after all, we'll see.

Just do not give up, Ulco.

Perhaps 3D-movies is too much for me and my wip's at the moment, but why shouldn't you try something easier at the beginning:

It could be a great experience to watch something like "harbour 1100 AD" in 3D on a poster. You only need 2 frames (left eye / right eye) and a stereo-image-maker. That's not difficult. For 3D monitors you make jps-files (there are different ways like side by side, top/bottom or interlaced) and for posters you make red-cyan (red/blue) anaglyphs that can be watched with the cheap red-cyan-glasses.

It would need some experiments for finding a good viewing point and the correct Zero par. dist but in general thhat would be much easier than a film.

A pity that there seem to be not so many (stereoscopic) 3D artists in the forum. I just know, what I taught myself...

Dune

I'm not giving up easily, thanks. But a bit reluctant about a whole, heavy animation. Perhaps my initial idea about a sequence of stills and invisible buttons, like manouvring in a game (Myst), is more interesting to do in 3D.

DocCharly65

I think the feasibility also depends on the (PC) capacity. I e.g. would have to wait several days only to check if a camera path works in 3D. If you have customers who generously subsidize such a project then a large animation is not so far-fetched, like for a hobby-graphic artists like I call me.

...makes me somehow feeling a little bit sad to have made the wrong job decisions 20-30 years ago... but who knows if I would feel better if I would work at pixar studios e.g. or if it would make me happy now if being creative on demand and under pressure would be my duty...  ;)

Dune

You're right. I have to see what the client has to offer in that respect. And regarding jobs; I graduated as a biologist, and now I'm just making images  :P But it's good to be free, not have a boss, and your own pressure to work under (and the clients').

Five years ago I was some sort of 3D-addicted. I created this animation in TG. It's for crosseyed viewing (a fantastic and simple way to check, whether your 3D effect works or not. Left and right have to be flipped, and it takes some time to practice to be able to view it like this).
First of all check the scale of the scene. I never used the TG-native stereoscopic camera function, but I guess you can adjust how much the left and right cameras are apart. In real life there's about 6 or 7 cm between the eyes.
For this animation I exported the scene into 3ds max, created a camera, and put a second camera 6cm next to it and attached it to the first one. Then I animated the main cam and reimported the chan file of both cameras into TG. Of course all this is not necessary anymore, since there is a native stereoscopic function in TG now.

I'd always create separate full color image sequences. There are some stereoscopic players in the web that can transform them into different stereoscopic formats like red/cyan or whatever else there is. As far as I know they can even export these other formats.

Dune

Neat, Hannes. Thanks for posting. Got a terrible headache now...
