Too many point clouds when importing to CloudCompare

Discussions
1

Hi,

When I export my scans as .stl and then attempt to import into CloudCompare (or solidworks for that matter) I get a warning. For example CloudCompare says “do you really expect to load 175729776 point clouds”.

I have tried to “simplify” my scans and all it does is give me a low resolution scan and the same error.

Any help is greatly appreciated!

Hi!
That’s a strange prompt in cloudcompare.

How man vertices/polys does it show for that mesh in RevoScan?
How big is your stl file? Can you maybe upload it somewhere to have it checked?

Hi,
It says 515221 vertices and 1030438 polygons. This is actually the sample file provided by the software (the bust). Here is a link to the simplified scan Dropbox that I exported for cloud compare. Even though this is the sample scan I have the issues with my own scans

I will check it when I am back home in about 1-2hrs.
What is the cloudcompare version you use?

It’s version 2.13.2. I had a similar problem with my old scanner software from next engine but I was able to simplify the model enough that cloud compare can open the files but I don’t lose any resolution in the scan.

Try to remesh/simplify it with Instant meshes,too.

thanks! I will give that a shot. Most of this is all new to me so I am trying to get a good workflow figured out

I have no problem importing the file ( which is a point cloud, .ply) into cloudcompare, version 2.13.alpha. nice scan :slight_smile:

interesting - did the same warning pop up and you just ignored it?

11

no warning popped up for me

this is what I get every time from the Revopoint scans

Install cloudcompare 2.13.alpha and try again.

I just installed latest cloudcompare 2.14.alpha and still no problem opening your file. :neutral_face:

ok thanks i will give that a shot

It is impossible for Revo Scan to produce this amount of points .

Your computer would be out of RAM before you try to export it .

Try to export always as .ply when you use Cloud Compare and not STL .

Something is very wrong with your exported scan and impossible .

I used a completely new scan this time of something I scanned. I cleaned it up in Revopoint and simplified it more than I would like. Exported as .ply and this is what I get. Happens every time

175 milion points ?! That’s crazy
Can you please provide the RS project to download ? You can DM me with the link .

That’s not proper behavior

I opened up your drop box file in cloud compare without any issues. No pop up for me.
This is what it gives me for number of points
