Chapter 8 Working with Particles 725
 In Local 3D (Faster): The default setting, renders particles faster but does not allow
for intersections with layers within the particles group or with layers in other groups.
 In Global 3D (Better): This setting allows the particles to intersect with layers within
the emitter group and with layers in other groups. When turned on, your project’s
interactivity is slowed.
Emission Latitude: Available when 3D is turned on, this control specifies the emission
direction (in degrees latitude) of the particles.
Emission Longitude: Available when 3D is turned on, this control specifies the axis of
rotation (in degrees longitude) from which the particles are emitted.

Tip: When working with elements in 3D space, you can quickly snap an object back to
its original orientation using the Isolate command.
Important: A project must contain a camera in order to access the Isolate option.
To isolate a group or layer, do one of the following:
m In the Layers tab (or Timeline layers list), click the Isolate button.
m Control-click the layer or group, then choose Isolate from the shortcut menu.
m Choose Object > Isolate.
m Click the Isolate button again to return to your previous view.
Note: Clicking a camera’s Isolate button activates that camera’s view.
Single-Cell Emitter and Particle Cell Parameters
The following parameters apply to the creation and motion of the individual particles
generated by each cell within an emitter.
