  • under Linux or Mac, type 'sh scan.sh'

You may build a shortcut on your desktop to start Scan faster.

Import a scan (i.e. point cloud)

File > Import a scan > choose a file to be imported

e.g. format (extract):

Tune the sub sampling rate

Edit > Sub sample

Choose the max number of points of the complete scan to be rendered to get a responsive user interface.

Note: this is only for viewing, all algorithms hereafter are run on the complete scan

Note : Scan is based on OpenGL and advanced viewing techniques, but sub sampling is generally interesting to be able to load big scans and keep a responsive user interface. Scan was built to work on a single plant / tree point cloud at a time.

Import a topology created on this scan by SimpleTree

File > Import a SimpleTree CSV

Move in the 3D view

Select one of the viewing tools and click / drag in the 3D view

Focus temporarily on a spheric region

Select the focus tool in the lateral bar

Select a focus sphere by clicking its center then dragging the mouse for the chosen radius. On click release, the view is restricted to the inside of the sphere

Right click or click unfocus to unfocus.
