Fog added to a scene
This command provides fog and smoke
atmospheric effects. This plug-in (page 3–995)
provides effects such as fog which causes objects to
appear to fade as they increase in distance from the
camera (standard fog), or layered fog that envelops
all or p arts of objects in a blanket of mist.
Fog renders only in Camera or Perspective views.
Orthographic or User views don’t render Fog
effects.
Pr ocedur es
To use standard fog:
1.
Create a Camera view of your scene.
2. In the camer a’s creation parameters, turn on
Show in the Environment Ranges group.
Standard fog is based on the camera’s
environment range values.
3. Set Adjust Near Range and Far Range to include
the objects you want to fog in your rendering.
As a general guideline, set Far Range just
beyond the objects, and Near Range to intersect
the object geometry closest to the camer a.
4. Choose Rendering > Environment.
5. Under Atmosphere on the Environment panel,
click Add.
