LowBudget Mirror Rig
 

Hello and sorry for bad english.

Preproduction of my BS-Rig is finished.
Some work to do (Case and angle-adjustment of the beamsplitter i will do in the future).
You can see some pics at:

3drig

I have 2 XHA1 mounted on a aluminium rig with a adjustable distance range between 0 and 80mm. (the complete range is about 200mm, but because the xha1 has a big wideangel optic you can see the aluframes on the bottom if i change the distance over 80mm).

The Beamsplitter was delivered from a german company.
The only parts i´ve to build with a CNC was the distance items for the xha1. All other parts are standard items you can buy everywhere.

Not showing in the pictures: field monitoring and sync-box.
The field monitoring is a laptop with 2 DV-inputs and viewing with the stereoscopic multiplexer from 3dtv.at
Or i´m using my selfbuilded headmounted videoglasses (left monitor-left picture / right monitor-right picture).
"Sync" is done by the stefra-LANC.

Regards,
Martin

i like it
 

i like your rig
the 3d rigs are expensive and you found a way to do it
the beamsplitter rig is the only way to to good 3d to big screens

is your mirror 50/50 or is like the teleprompter mirrors 40/60 ?

how much was the mirror?

can you provide us the link to the mirror company?

thank you.

Avatar aparently didn't use mirror rig, but of course they didn't have so big budget constraint. YouTube - The 3-D Camera Technology Behind James Cameron's Avatar

Great rig
 

Thanks for this link

the rig is great, it changes convergence togheter as you do focus.

I saw Avatar without glasses in some moments and it seems they keep the convergence in the focus point all the time and convergence changes inside the same scene if needed. in this way all the cuts keeps confortable to the brain because the eye acomodation is always in the screen plane

and it is the most easiest thing to do, the good old Nuview was doing that very fine.

The new Panasonic one piece rig, not on the market yet is also side-by-side. The booth person mentioned that they'll not be changing inter occular distance, just convergence. He also mentioned that the keystoning effect will be corrected for in the camera immediately, so there would be no post processing impact.
