Thank you!
Removing of objects seems not to be possible?
Searching in this forum I found:
http://www.worldviz.com/forum/showth...ghlight=remove
"Currently you can't remove an object from memory, but you can make it invisible as you already did. We are hoping to have this feature by the next release also."
So the workaround is:
gliderObj.visible(False)
instead of gliderObj.remove()
