Procedure
Many dynaflector parameters are the same as
those for omniflectors. However, the procedure
of associating the dynaflector with both the
particle system and the object to be affected is
more complex than the simple binding used by
omniflector.
To create a particle/dynamics system:
1.
Create or load a scene containing a
non-event-driven par t icle system (p age 2–233)
and an object to be affected by the particles
(hereafter called "the object"). Position and
orient the two as desired so that the particles
strike the object.
• The icon for the part icle system must be
visible in at least one non-disabled viewport.
• On the Basic Parameters rollout of the
particle system, set Percentage of Particles
to 100%. Otherwise, only those par ticles
displayed in the viewport wi ll be calculated.
2. OntheCreatepanel,click
SpaceWarps. ChooseDeflectorsfromthe
drop-down list, and then click one of the
dynaflector buttons (PDynaFlect, SDynaFlect,
or UDy naFlect). Drag in a v iewport to create
the deflector.
3. Do either of the follow ing:
• If using a PDynaFlect or SDynaFlect,
position the space warp icon where the
particles st rike (or will strike) the object.
Resize and orient it as needed.
Also, link the PDynaFlect or
SDy naFlect as a child of the object. This
step isn’t absolutely necessary, but allows the
deflector to follow the object as it moves.
• If using a UD ynaFlect, go to the Modif y
panel > Parameters rollout, click the Pick
Object button, and then select t he object.
Thepositionofthespacewarpicondoesn’t
matter, and it’s not necessary to link the two.
4. Bind the particle system to the
dynaflector using the toolbar
Bind to Space
Warp button (page 2–54)
.
5. Go to the Utilities panel and open the
Dynamics utilit y.
6. OntheDynamicsrollout,clickNewtocreatea
new simulation.
7. ClickEditObjectList,andaddtheobjecttothe
dynamics simulation.
8. ClickEditObject.OntheEditObjectdialog,
click Assign Object Effects and assign the
dynaflector to the object.
Note: Because only those particles displayed
in viewpor ts are used in the dynaflector
calculations, solving the dynamics involves
three requirements:
9. On the Dynam ics rollout, turn on the Update
Display w/Solve check box above t he Solve
button.
10. Solve the simulation.
