Steps causing the bug to occur
- Run the attached composition.
- Move hand slowly above the Leap Motion device.
The top 2 points (representing x- and y-axis) move smoothly, but the bottom point (representing z-axis) doesn’t. It seems like it waits for the hand to stay at a high or low z-position for some threshold of time before it updates.
How did the result differ from what you expected?
Movement along the z-axis should look the same as along the x- and y-axis.
Other notes
- Vuo version: 0.9.0
- macOS version: macOS
@bnvisuals commented on Leap motion refresh rate and general performance :
Just plugged in my leap after all this time, on a new computer, and I’m experiencing some glitches. The Z-axiz is choppy. Any Idea why this would be?
In Vuo 0.9.0, we updated the Leap nodes to use the “stabilized” tracking data provided by the Leap Motion software. This was overall an improvement, as it fixed the constant shakiness in the data.
But, according to https://community.leapmotion.com/t/z-axis-accuracy-is-not-good-as-x-axis-or-y-axis/1376, a side effect of using stabilized data is that, for some reason, the z-axis doesn’t track as well. The difference is apparent if you run the attached composition (080 and 090 versions) in Vuo 0.8.0 and 0.9.0.
Next steps:
- Try updating the Leap SDK version used in Vuo.
- If that doesn’t fix the problem, file a bug report to the Leap Motion developers.
