Rhino 9 WIP: PointClouds not displayed correctly

[tobias.stoltmann]

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.

OpenGL vs DirectX performance with point clouds

I just downloaded the WIP. Looks really nice so far, but there is a big performance hit with point clouds with Direct3D. OpenGL still works good. EDIT: I have an rtx 4070 with latest nVidia drivers.

Display: Direct3D: Point Cloud Performance Issue : RH-90644

A work-around is to use OpenGL instead.

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.

RH-90644 is fixed in the latest Rhino WIP. Please give it a try.
