thomo / Sandbox Anleitung.md
Created April 25, 2016 12:36
Anleitung für die Einrichtung einer "Terraforming Sandbox" entsprechend http://idav.ucdavis.edu/~okreylos/ResDev/SARndbox/

  • Terminal Fenster öffnen (Symbol ">_")

  • "./start_sandbox.sh" eingeben -> enter

  • es erscheint ein Fenster "RawKinectViewer"

    • links: "Tiefenbild" der Kinect (eher blau)

    • rechts: Kamarabild der Kinect

    • Ausschnitt des Tiefenbilds vergößern, so dass Sandbox möglichst groß zu sehen ist
