Dense Cloud Generation + Network Processing = Stuck at 5%
« on: December 14, 2022, 03:04:56 AM »
Hi all,

I am trying out network processing for the first time to see if I can speed up my very large projects. Normally I generate a mesh from depth maps, but I discovered that making a point cloud first gives me the ability to remove trees, cars, and houses before making a mesh (these look bad in the final product and removing from the mesh has proven to be difficult and laborious).

My current project has over 22000 35 MP images in EXR format. The photos are on two drives, but both drives are shared on the network and both nodes can access all the photos. The depth maps are already created in Medium quality, and I am reusing  the depth maps to generate a point cloud.

Currently, the Network Monitor shows the progress is at 5% and it hasn't progressed in the last hour.

Should I continue to let this run or do I need to change something in order for this to work?

I do not have any tweaks enabled and the images cover a 5 km road, so each photo has probably 15-20 neighbors max.

Also, the monitor shows this running on 1/1 node, so I'm wondering if it's still figuring out how to split up the job.

The CPU on the active node is at 100% but it's barely using any memory or disk.. So it's doing something, but I don't know what!

Any advice is appreciated. Thanks!

This is what the log states currently:

It took over 2 hours but eventually it moved past 5%. I'll leave this up in case others have a similar problem. I believe it was spending that entire time determining how to divide up the task.

Hello jenkinsm,

How does the area covered by the images look like in respect of the bounding box? Also if you haven't cancelled the task, please provide later the information about the number of sub-tasks that is the dense cloud generation procedure split into.

Also I have a side question regarding the source data sharing - are the both network drives that you have mentioned accessible through the same root path?
Best regards,
