2d video into a 3d model?
show user profile  skydejay
Hey guys!

I'm new to these forums and I am also new to 3ds max. I switched from maya because i couldn't render to avi files.

I have two questions: the first being the less important one. "Can you export models from Maya into formats compatible with 3ds?"

The second one: (this one is more important) "How can you take a 2D video and make a 3D model of it?" Don't tell me it's not possible because the avatar guys did it. But how? Did they have special cameras, software, connectors, hardware, what? Any help is appreciated!

1: Use .obj or .fbx

2: This should give you an idea of their technique:

"How can you take a 2D video and make a 3D model of it?"

uh, i'm not sure i follow you here, as far as I'm aware of the shots that required real elements used stereoscopic cameras, everything else was modeled traditionally.

Also that's the worst excuse for dropping maya, you shouldn't be rendering to AVI's anyway you should be rendering to image sequences and then import them as such into compositing or video editing apps.

ok neither *.fbx or *.obj worked. .obj acted like it would, but nothing showed on anything. .fbx said that it wasn't compatible.

Also, Kajico, why should I be doing that? that just takes so much longer.

if your looking to take a video clip, run it through a neat little program and get a 3d model as a result you are gonna be disappointed. while there is work going on in the area of making a program understand and correctly translate 2d video feed into a 3d representation and some success in areas where detail isnt very important there is still a long, long way to go. hence all the cutting edge reality->3d pipe is still using either lasers, multiple cameras, color immune light spectrum, acoustics or often a combination of these.

as for the why image sequences, well simply because the built in video encoders have rather crappy quality

well I can't say I expected THAT but I expected a way that was a little easier (and waaaay less expensive) then what you stated.

And I find the AVI renderer in Max just fine

Max (and pretty much any 3D program) has the tendency to crash while rendering whether because memory allocation wasn't available a glitch in the render engine, or Windows deciding it hates you more today than before.

In those situations when you render to AVI your long ass render that took hours to do has gone corrupt now you have to start all over again. The proper way is to render out the frames in sequence. This is so that if the application fails or crashes you can pick up where you left off again.

Use Video Post in Max. It is made for doing stuff like that.

Also, you shouldn't be rendering to JPEG as that will introduce image degradation before you compile the final video. As a rule of thumb, you should only compress and image or video once to maintain the highest quality possible.

Also, FYI

incase your freaking out because you're currently imagining rendering every single frame manually, its not like that. its exactly the same process as rendering to AVI, just that max saves a few hundred or thousand images instead of one single crappy file. then its a matter of opening after effects, importing one frame as a sequence and it all goes in magically as though it was a video file.

also to augment what people have already said, the Avatar people didnt make 3d objects from 2D video. the 3D models were already made, they used video to help animate the models using a process called motion capture.



He who says it cannot be done is interrupting the man doing it.

3d scanning can be done with reasonable accuracy on the cheap.

look up David 3d scanner. it was developed for the reprap community, all it takes is one camera, a plain backdrop and a 30$ laser.


It scans with impressive accuracy, I was looking at some scans up on thingiverse and one that really stuck out to me was somebody scanned their grandma, and the tiny wrinkles on her face were all there.

Also, somebody on the reprap forums wrote a quick program that stitches parts of a scanned object together (since the scanner can only do one side of an object at a time)
