Extremelly slow in editor cloud selection

Post by PablerasBCN »

When I load multiple clouds, if I select a cloud graphically in editor by clicking it it takes FOREVER to resolve that selection and show it selected in the tree. I wonder if I can enable any option for this not to be so extremelly taxing operation. Mouse may even enter "thinking" mode.

What is your graphic card? We use the picking mechanism from the driver and some cards/drivers do this very badly....

I've a GTX 1080, drivers if not latest sure are very recent.

AS the cloud number increases, the time in the selection number increases a lot.

Was the picking this slow before?

Could you specify the typical numbers of clouds?

Did some testing

68 clouds from the same dataset that int total sum 22M points the lag is aboug 2 secs

about the doublé of the dataset 3-4 secs. Seems scalates linearly.

May be could be interesting to add an option of instead of point pick do bounding box pick, I believe that would be ultra fast.

and to make it clear is not that jsut the bounding box gest rightly displayed as cloud selected, that takes 2-3 secs later on the software gets bit freezed until is operational again. That is the most frustrating part.

Yes but also ultra-inaccurate.. Especially when the clouds are intricate.

Actually the OpenGL picking mechanism is deprecated, and this explains why drivers don't implement it very well nowadays... We should probably change this.
