Usage and controls
The reference application has a wide range of options for both up-front user configuration and interactive features to be used as the forest is rendering.
Navigation
Navigation on a PC is handled with the standard WASD + mouse navigation. Press and hold the middle mouse button for free-look mode. Use the right mouse button to raise and lower the camera (must deactivate terrain following). Other navigation-related keys include:
| Key | Behavior |
|---|---|
| Control | Hold to move more slowly |
| Shift | Hold to move more quickly |
| Space | Toggle terrain following |
| C | Toggle collision (will allow the camera to move through the terrain if terrain following off) |
Note
Navigation in the Linux version of the reference application has some limitations.
