3D Scene + Map

3D navigation

mouse left button	look around
mouse right button	move camera forward/backward
mouse wheel (scroll)	change field of view (= camera focal length)
mouse wheel (drag)	move camera over its XY (= parallel shift)
r-key	reset view (heading = initial, tilt = 0, roll = 0)
t-key	reset view (heading = initial, tilt = initial, roll = 0)

Comparing 3D model and Map (satellite imagery) measurements

• Place a marker in the 3D scene near the feature of interest. Drag the marker closer if needed.
  This will set the 3D model distance.
• Drag the corresponding marker over the map to what looks like the feature of interest to set the map distance.
  If the show marker info is enabled the distances and the difference will be displayed.

Update measurements:

• Map distance - drag marker over map
• 3D model distance - drag marker over 3D scene

Map

ctrl + left click	create markers, relative height = 0 remove markers
draggable objects (global XZ)	markers camera base (green) heading crosshair (white)

Scene

ctrl + left click	create marker, relative height = surface hitting point height remove marker
draggable objects (stick to surfaces)	markers only
