Add Noise to 3D Object Coordinates Issue

Steps causing the bug to occur

  1. make 3d point grid
  2. add noise to 3d object
  3. point coordinates are not displayed properly

Have you found a workaround?

D500 issue occurs. 750M Does not occur.

Other notes

  • Vuo version: 1.2.6
  • macOS version: OS X 10.11
  • How severely does this bug affect you? It prevents me from completing a specific task with Vuo.

Thanks for reporting this problem, @krezrock. We tested on a couple different computers and didn’t see the problem, so it looks like it’s specific to the GPU. What GPU do you have?

@jstrecker This is occurring on D500. Confirmed, Does not occur on 750M.  

OK, thanks.

We’re able to reproduce the problem on an AMD 7970. It happens in 1.2.6 but not 1.2.5.

Looking at exactly what changes caused the wrongly positioned points, we found that it was the workaround to the driver bug that caused crashes on AMD GPUs. The exact thing that fixed the crashes caused some of the 3D object filter nodes (Add Noise, Explode, Trim) to give wrong output.

So, we’ll see if there’s a workaround to what appears to be a second driver bug.

Understood. Thank you for the information.

Implemented in Vuo 2.0 beta.
