Open a scan, explore its shape, and inspect its coordinates.
Try the sample pavilion, rotate to see the roof, then use Fit view to return to the whole cloud. Change Point size to make sparse areas easier to see.
The viewer displays up to 80,000 sampled points. Measurements use those preview points and source coordinate units; they are not survey-grade measurements. Uploading sends the file to the server for processing.
Yes. Download selected cloud returns the normalized PLY, while Download original upload returns the unchanged source file. You can also continue to crop, subsample or convert the selected cloud.
Files stay in a temporary 2-hour session. Switching tools in this tab keeps your uploaded clouds and results. Read about file privacy.
The counter below the viewer shows both numbers. Up to 80,000 points are displayed to keep the scene manageable. Cropping and subsampling still operate on all points in the selected cloud, and downloading the selected cloud does not download just the preview.
Extent is the difference between the maximum and minimum on each axis, in source coordinate units. If the source uses meters, these values are in meters; the site does not detect or convert the unit. Fit view frames the cloud without changing its coordinates.
Rotate to inspect the shape and adjust Point size when the preview is hard to see. Measure uses two picked preview points. For a small feature that is hard to inspect, crop its surrounding region and view that new result.
The result receives its own sampled preview. A smaller region may display more of its points than the overview did. Compare total point counts and bounds as well as the image.
Retry the preview after a connection problem. If the browser cannot provide WebGL, processing and downloads can still be used. An unavailable preview alone does not mean the uploaded file is invalid.
