Hi,

i have again a (stupid) question. I have a table with 100.000+ lines. These lines are not all visible of course. Is there any way to find out, which lines are currently visible? I couldn't find any way to do this, but I might be blind.... Sad

All lines that are visible are known by the ViewportLayer. So you could iterate over the positions in the viewport and translate position to index. That's the only way I could think of ATM.

There is no API to simply ask which lines are visible AFAIK.
