OT: reverse engineer a vr shoot to 3d scene and some other questions

[Gerbrand Nel]

Hey guys
I might have mailed this to 3dpro earlier by mistake :)
Was suppose to be here, although 3dpro might not be the worst place to 
ask these questions.


Anyway..
Really exited to be pitching on a vr project!!
The project would consist of a spherical stereo shoot for the mid and 
far ground, and pre-rendered cg for the foreground.

My questions:
Does anyone know of a way to generate a rough point cloud of the 
environment, from the two spherical images you get from shooting 360 
stereo?
My guess is that this will help allot to place the cg into the 
environments.


Has anyone used this rig, or know of something else in this price range ?
http://www.izugar.com/product/z6x3d.html

How big a problem is sync when shooting with multi gopros?

In the past I used whirligig, but with the new oculus runtime, I 
switched to building my own vr player in unreal. What do you guys use to 
publish vr content to clients?


Thanks
Gerbrand

Re: Object motion converted to path animation but normalized atorigin?

[peter_b]

if I read this correctly – you’re just doing position – not orientation right?

it works in ICE like this:

for a null path constrained on curve.
make an identical copy (null1 on curve1)

[( null global pos – curve global pos ) multiply by –1 ]   >> translation port 
of an SRT to Matrix >> set curve1 global transform 

null1 stays put at the origin...

I’m probably oversimplifying things?

here is two scripts, one to set up the scene so you can see the scenario to 
start, and then another to normalize the motion per David's simpler method.

  Not really, I have it working how I want now, I had come up with my own way 
but also David Barosin on the SItoA list (I accidentally posted there) gave me 
a simpler answer. Here is David's response... 



If the plane is on a curve, a hierarchy of 2 nulls could do it.  
The parent null is constrained to the plane. The child null is constrained 
to the curve.  Plot the child null's position. 
Remove the constraints from both nulls. 
Now constrain the curve to the child null and zero out the parent null's 
SRT.   
Hope that makes sense.
