8. if color is important for your exported data be sure to create a project point cloud before exporting However if the project does not already have a project point cloud it is always faster to use the filter directly Notice SCENE will issue a warning when creating a clipping box with no project point cloud present This is not a problem for ATS Uniform Filter the clipping box can be used anyway ATS Advanced Technical Solutions AB All rights reserved ATS 4 Resource usage In most cases with modest exported volumes or single scans the resource usage should not be a problem for a modern computer Memory usage should be around 1 2 GB plus what SCENE is using However the filter can use a lot of memory for large exported volumes a factory of 100 x 100 m for example It can also use up to 8 CPU cores The filter will cache data to the temporary file folder in Windows if running low on memory so make sure there is 1 2 gigabytes available on the C drive when exporting large volumes The exported files can also be large for large volumes or high resolutions especially the xyz or pts formats 5 Output file types 5 1 5 2 ATS Uniform Filter can currently save output in four formats E57 and xyz pts and a customizable format E57 E57 is a binary 3D point cloud file format created to simplify 3D point cloud storage and usage between different applications Find out more about the E57 format at these links
