## 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
