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.
A work-around is to use OpenGL instead.
Options > View > GPU > GPU Technology
A guess is available memory, either RAM or video, is a limit. If so then different systems would have different limits.
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).
Paging @stevebaer . Perhaps this warrants reopening RH-90644 or maybe a new issue.
@tobias.stoltmann can you send me one of these files that does not display the points?
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.
