I'm trying to make a simple patch to control the NVIDIA GeForce GT 750M 2048 MB card on a laptop. The intention is to send 2 ProRes files that contain 3D video.

My simple patch tries to open both Left and Right archives and play them back at the same speed (although i have the impression one is some miliseconds behind). My problem is that I don't seem to find the way to tell jit.window to go fullsrceen on each video out independently so each video projector gets the correspondent Left file and Right file.

Attached is my naive first attempt. If someone could advice me on how to (if possible) get the Nvidia card mentioned above to display both files through separate video outs (hdmi + minidisplay/thunderbolt) would be greatly appreciated.

the 1st has one window with 2 positioned planes

the 2nd has 2 windows (with shared context) and 2 planes.

In this 2nd setup, make sure you position windows in the correct Display monitor/ Beamer before you hit render.

as for playing the 2 movies in sync you could just make sure you send the [t start frame 0] to both players

in that case I would make sure that both have @autostart 0 [jit.movie @autostart 0]

Oops just realized I didn'T explain much.

To take advantage of your graphics card , you use gl objects to talk to the gpu .

TO DRAW your gl objects to a context you need

these taking care of the output & creating 3d world

then you have 3d object/ primitive shapes/ 

in your setup I used a [ jit.gl.videoplane ] which creates a 3D plane which can be rotate x y z / position / scale . 

Another bunch of shapes can be created using the jit.gl.gridshape @shape sphere OR @shape cone etc... check out the attrui .

Then finally , on these shape you place a texture (a skin) GPU pixels if you will :-)

Finally, everything communicates with names no wires needed!

jit.gl.videoplane can be setup like this [jit.gl.videoplane dog @texture myskin ]

you can also do it directly with jit.movie like this

[jit.movie @output_texture 1 @texture_name myskin ]

to drawto the render context you set jit.movie like this

[jit.movie @drawto dog @output_texture 1 @texture_name myskin @automatic 1]

There is two types of Jitter techniques.
CPU jitter and GPU Jitter.
To take advantage of your graphics card , you use gl objects to talk to the gpu . 

TO DRAW your gl objects to a context you need 

[qmetro 30Hz or 60Hz ] 
[t b erase]
[jit.gl.render contextname ] 

these taking care of the output & creating  3d world

Phiol, thanks a lot for the answer, unfortunately work has got me busy and without time for testing your code.

Look fwd to report here once I have the chance to play with 3D movie files and the passive projectors setting.
