point count pop to pango chop beyond

POPs
1

Hi everyone,

I’m fairly new to TouchDesigner and working with lasers, so I’m still figuring out some of the fundamentals.

I have a Line POP connected to a Primitive POP with “Delete Primitives and Keep Points” turned ON. In TouchDesigner, the point count shows 17 points, which is what I expect.

However, when I connect this to Pangolin Beyond, Beyond reports a point count of around 270 points instead of 17.

Is there a clean or recommended way to ensure that only the original 17 points are output to the laser?

Thanks in advance!

The point count on the BEYOND side refers to the total number of samples required in the laser signal to actually draw the shape. Because you are drawing a bunch of dots, the laser will need to keep turning off and on again (ie. blanking) which will contribute to the overall number of samples required. If you instead referenced line2 you’ll notice the overall sample count goes down on the BEYOND side because it no longer needs to do all that blanking. But of course, they will never match 1:1 because what is sent to BEYOND from TouchDesigner only defines the shape used to generate the laser signal samples.
