I am visualizing point clouds in Cesium using Cesium3DTiles.
I created a Widget that allows me to pick the tiles like this:
var pickedObject = that._scene.pick(mouse.position);
Debugging shows that pickedObject is an object with the 'primitive' property, which is a PointCloud3DTileContent.
Usually, I can find the positions of every single point in the '_parsedContent' of the PointCloud3DTileContent. But pickedObject.primitive._parsedContent is undefined.
Why is it undefined? I am picking a point which exists in the current frame.
I hope you can help me.
