setup two wall system with one single PC and one quadro graphics card

Do you see the discontinuity between the two windows when viewing on a desktop? If so, can you post a screenshot.

Or do you only see the discontinuity when viewing on the actual projected surface of your CAVE? If so, then your projectors might not be properly aligned.

Hi,

I am currently working on a two wall system which is driven by the same computer and one graphics card. I generated one front image and one floor image.

The screenshot is attached. Is this due to the projector alignment problem?

Thanks.

Are you sure the dimensions of the wall you are specifying in your script match the physical dimensions of the projected image? Also, the physical coordinates of the wall must be in the same coordinate frame as the tracker you are using to track the users head position.

I am sure the dimensions of the wall is correct. I am not currently using any physical tracking system. The cave center is assumed to the origin of the coordinate system.

I suspect if the left and right eye image of the bottom screen are swapped while it is not for the front screen. How do I swap images for a particular screen. Is this possible in vizard?

The complete code is listed below.
