1. A concise explanation of the problem you’re experiencing.
The original problem I was having was presented as a resolution no better than once per 60 seconds on a path being drawn with a SampledPositionProperty.
Code copied from the Interpolation sandcastle example (changed to 1 degree increments in the for loop).
In sandcastle I see a smooth round circle. In my electron environment I see a hexagon. (see attachment)
It turns out that debugging lead me to reallySubSample in PathVisualizer.js. The “property instanceof SampledPositionProperty” check is failing. (This gives you a resolution of 60 from the Math.max in subSampleGenericProperty.)
As a test I changed the test to if( property.constructor.name === “SampledPositionProperty”) and it works as expected.
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
4. The Cesium version you’re using, your operating system and browser.
I have tested Cesium 1.59 and 1.60 in electron on a Mac.
It seems to be an environment issue, but I don’t know where to go from here.
