Fog added to a scene
This command provides fog and smoke
atmospheric effects. This
plug-in (page 3–1089)
provides effect s 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 parts of objects in a blanket of mist.
Fog renders only in Camera or Perspective views.
Orthog raphic 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 camera’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 objec ts 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 camera.
4. Choose Rendering > Environment.
