Hi, I just happened to notice that if I read a pointcloud in Rhino 9 WIP it does not zoom correctly to the pointcloud. E.g. when I use “Zoom Selected” nothing happens. Thanks, T.

Update: Reducing the cloud from 144 million points did the job. But it was properly displayed in Rhino8!

I have a point set with 436 million points. Is there a maximum number of points allowed in a Rhino point cloud?

There has been a problem with large point clouds in the WIP when Direct3D is used. I don’t know if this is related. [image] OpenGL vs DirectX performance with point clouds Serengeti (Rhino WIP) I just downloaded the WIP. Looks really nice so far, but there is a…

I just haven’t gotten around to fixing this issue yet for Direct3D. The Youtrack issue that David references is the correct one and will hopefully be worked on soon.

@dan I just noticed this issue again in BETA (9.0.26209.12553, 2026-07-28). When I open a pointcloud with approx. 500 million points it does not display.

@dan Reducing it to 125.776.914 points helped. But of course it would be nice to work with the huge file as well (as it works in Rhino8).

@tobias.stoltmann can you send me one of these files that does not display the points?

@stevebaer , I have sent you are large-ish E57 (5.5 GB) for testing. We are also observing the PC display problem that Tobias is reporting. --Axel
