5.0

The dimensions of the collision volume are user definable settings for the current view or as a global
option. See Section 13.5, “ Editing Viewpoints ” and Section 13.6, “ Viewpoints Options ” for more
information.
Collision detection is only available when in either the walk or fly navigation mode.
To activate collision detection:
• In Walk or Fly navigation mode, go to Viewpoint, Navigation Tools, Collision Detection
or
• Click Collision Detection on the Navigation Tools toolbar.
or
• Press D to toggle collision detection on/off.
Note
When Collision Detection is turned on, rendering prioritization is changed so that objects around
the camera or avatar are displayed with much higher detail than normal. The size of the region of
high detail is based on collision volume radius and speed of movement (needing to see what is
about to be walked into).
8.9. Gravity
This function only works in connection with collision detection.
Where collision detection gives you mass, gravity gives you weight. As such, you (as the collision volume)
will be pulled downwards whilst walking through the model scene (gravity is only available when in the
walk navigation mode).
This allows you to walk down stairs, for example, or follow terrain.
To activate gravity:
• In the Walk navigation mode, go to Viewpoint, Navigation Tools, Gravity
or
• Click Gravity on the Navigation Tools toolbar.
