Describe the bug Dont know if its a bug but anyway.

I use ODM that uses openMVS for pointcloud reconstruction, when i pick points in CloudCompare the accuracy is just two decimals. looks like 24.10009 or 24.199999, clearly the decimals is just binary to real number conversion problem.

I would like three decimal accuracy

To Reproduce Make a pointcloud

Expected behavior

the points should have three decmal accuracy.

Hi Andreas,

The accuracy computed by OpenMVS is a full 32 float. I think the issue is at exporting the point cloud from OpenMVS format to PLY or whatever format ODM uses.

I'll loop in @pierotofy

I export in LAZ, the default.

I don't think this is an issue in OpenMVS.
