During this period, we were using TouchDesigner to control the laser. Referring to online examples and using TD templates, we encountered several issues, involving the Laser and Pangolin chop.
We used a Laser template containing a continuously rotating cube. If we directly connected the sop to the Pangolin chop, the image was very smooth without flickering, but the laser-projected cube was distorted, especially at the corners, which became rounded, and the lines became multiple.
In the second case, we inserted a Laser chop between the sop and the Pangolin. This prevented the cube from distorting, but the laser projected dots instead of lines, and the image became choppy and unresponsive. After adjusting some parameters, it could project lines, but the image flickered and couldn’t project a complete cube.
We tried many adjustments, but none seemed to work.
The Pangolin CHOP is not meant to be used with the Laser CHOP, as the Laser CHOP generates the signal for direct usage with a laser device, whereas the Pangolin CHOP expects only the shape/anchor points (and BEYOND will generate the laser signal).
It sounds like the problem here is the missing camera/projection parameter from the Pangolin CHOP. There is an RFE for this but we haven’t gotten around to adding it yet:
As a work-around, you could apply a camera transform to the input points before sending to BEYOND via the Pangolin CHOP. This thread here (reference in the above thread) could work for your case:
