Gizmo/Center
Examples of gizmos:
Left: Gizmo for a Bend modifier
Right: Gizmo for UVW mapping
A gizmo is geometry that appears in viewports,
but not in the scene. You manipulate a gizmo to
modify the scene geometry or other effects. There
are gizmos for transforms, modifiers, atmospheric
apparatus, and some directly modifiable geometr y
such as spotlight cones.
For modifiers, a gizmo acts like a kind of container
that transfers the modification to the object to
which it’s attached. You can move, scale, and
rotate the gizmo as you would any object, altering
the effect of the modifier on the object.
With
bipeds (page 2–691) ,thefootstepsin footstep
animation (page 3–1037)
are gizmos that let you
edit the position of the biped’s feet over time.
Physique (page 2–927) uses gizmos to visually
identify bulge angles.
Some modifiers with gizmos also have a
center sub-object, which can be manipulated
independently of the gizmo to specify the point
about which the deformation, etc., takes place. For
example, moving the Bend modifier center parallel

thebendcircleandthelocationofthemodified
object within the bend circle.
Global Event
The first event (page 3–1029) in a particle flow
(page 3–1036)
is always a global event, whose
contents affect all particles in the flow; the rest
are
local events (page 3–1057) .Althougha
global event has the same name as the Particle
Flow source icon, selecting the source icon in
a v iewport doesn’t highlight the global event,
nor does highlighting a global event select the
corresponding source icon.
Global event (highlighted)
By default, the global event contains a single
Render operator (page 2–202) that sp ecifies
rendering properties for all particles in the flow.
