I’ve been trying to do this by adding some values to reposition the camera and using the COSM externals but can’t seem to figure out what to do, it seems to be wrong somehow

There might also be better way so if someone could enlighten me that would be great

It really depends what you are trying to do, do you want to render normal jitter matrix stuff and movies etc or are you rendering GL stuff, or both?

Search on the forums for ‘multi projector’, ‘multi projection’ and ‘edge blending’ etc and you’ll find tonnes of stuff.

I am only drawing gl stuff and figured out the camera positions in 3 separate GL renders, keeping an average fps of 20. I just thought there was an easier way of doing this than draw each jit.gl.object in each of the separate engines

This way people can now x/z axis from ground projection and height (y axis)of the gl object they are controlling by looking at the side view.
I guess your hinting at the @capture for the whole scene but I get lost trying to wrap my head around that.

without the cosm it looks like this at the moment:

I am using a Matrox Triplehead2go so I can create one large desktop to send the window to and that gets split across the three projectors. I’ve pasted a simplified version of what I’m doing to capture the scene (assisted by Mr. Benson!), but it doesn’t take into account getting a side view of your scene and I’ve left some gaps around the edges so you can see what’s going on. Hope it helps some:
