of orthographic views: top and bottom; front and
back; left and rig ht.
Orthographic views are a spe cial case of
axonometric v iews (page 3–913).Youcanset
viewports to the various orthographic views using
the viewport right-click menu (page 3–731) or
keyboard shor tcuts (page 3–871) .
Out-of -R a nge Ty pes
When you specify values and keys for a controller,
you are defining animation over a range of time.
YouchooseOut-of-RangeTypestodeterminehow
the animation continues outside a specified range.
Out-of-Range choices include holding a constant
value, and various ways of repeating the animated
range.
The easiest way to work with Out-of-Range Types
isintheTrackViewFunctionCurvemode.
You use the Parameter Out-of-Range dialog to
project the pattern of the key dots in the selected
track. These p atterns are applied to the animation
outsidetherangeofallkeysinthetrack. Thisis
why they’re called out-of-range types.
By default, tracks use a constant out-of-range type.
This means that the track va lues before and after
the range of keys remain constant. For example, in
a 100-frame animation with keys up to frame 20,
theX,Y,andZvaluesafterframe20remainthe
same for the rest of the animation. The objects in
this example do not move from frame 20 to frame
100.
Applying the Cycle out-of-range type will make
the key pattern in frames 0–20 repeat c yclically for
the remaining 80 fr ames.
Outputs: Source / Test
In Particle Flow, you create a particle diagram
(page 3–989) by connecting events (page 3–935)
using wires (page 3–1033). E ach wire links an
output with an e vent input (page 3–957).Thereare
two different ty pes of outputs: ;
• The connector sticking down from the bottom
of a global event (page 3–949) is a source output.
• The connector sticking out from the side of a
test (page 3–1021) is a test output.
