SpeedSix.TrailPath
PURPOSE
Draws a trailing brush along
a path set by up to 7 key points. A whizzy whacky trail not necessarily
related to the input action.
INPUT CLIP
TrailPath Clip:
to draw the trail on.
Brush Clip: to create
brush from.
Setting Up
-
originally there are only 3
points displayed to be used to create the path along which the trail swoops.
-
drag them around to suit.
-
turn on more points as you will,
and set up the path to follow.
-
there are default Z Point
values set but they will not be used unless called for. Read on.
-
the length of the trail is set
by Head/Tail Fade; the number of frames positions along the path
to fade out over.
-
Peak Position controls
how far along the trail path the brightest point of the brush is, measured
in percentage of the line length.
-
the Path Resolution will
set the smoothness of the curve of the path. The minimum is 5 but that
is rather an angular path missing some of the control points!.
That is the basic setup to trail
the default brush.
The Brush
-
you can set the Size, Orientation
and Intensity; though the orientation will only become really noticeable
when you use a brush other than Blob.
-
the Seed will only have
a minor affect on the basic Blob brush patterning.
-
the colour of the trail can be
set either using Own Colours which are taken directly from the colours
in the brush chosen, or from the RGB settings. With Trail Only you
get a trail of the one chosen colour, while with Blended you can
have a change of colour over the trail length.
-
you can read in an Image
to be your brush mark or select a paint Brush to draw with. Make
your choice and use the Browse button to select the desired brush.
-
if you want to you can cut out
part of the second input clip to use as the brush. Select Boxed Luminance
and a magenta overlay appears.
-
Drag this into position to define
the brush.
-
select for Over or Add
for the way the trail is composited with the background image.
Adding Depth
Beware this can slow things
up! but adds another dimension to the trail.
-
for each point used set a value
for Z Key going from -5.0 (furthest away from you) to 5.0 (nearest).
The overlay circles will change size a little to give you an idea of which
point is where in Z.
-
as the distance away changes
a smaller/larger brush is drawn. The trail can then appear to grow/shrink
along its path.
-
the size calculated always refers
to the Base Size setting as a starting point.
-
switch from Basic to
With Z Depth and observe.
Rotating the Brush
-
set up key frames for the Orientation
control.
-
select With Rotation
and the brush is rotated along the path adding a swirly motion.
-
the Z Key information
will be ignored!
-
put both the Z scaling and the
rotations together with Both Z and Rotation. As you can imagine
a lot of brushes have to be scaled and rotated at this point so things
can slow down.......

Use lower resolutions for
faster results but less detail.
SOUND
Channel curves from SpeedSix.AiffExtract
can be imported into the Amplitude Import curve to control any of
the animation channels.
Import Amplitude File
Using the file browser select
the file you saved in SpeedSix.AiffExtract. The data is then loaded into
the Amplitude Import channel.
Amplitude Import
( Min: -1000.0 Max: 1000.0)
The value range of this
channel matches the potential range within
SpeedSix.AiffExtract. Scale
and translate the imported channel data to match the value range of your
target channel. Use the usual copy and paste controls to
get the sound information into the desired animation channel.
HELP gets you here!
Reset sets default
values for the current frame.
