Compositions Provided by SynVisum (Animation Natural)


Meteor (Animation)



Generates meteor.
(This composition requires Mac OS X 10.6 or later)
When the Mix Fader is raised from minimum, always start.
In this case, if the Mix Fader is rised to maximum within 0.5 second, starts at this point (to show as bright as posiible).
If 0.5 second elapse, starts automatically, regardless Mix Fader position.
"Start" and "End" are specified as "0" for center of screen, a width of a screen correspond to "2.0".
"Range" is a width of randomizing "Start" and "End" automatically.
"Move" is time to move (in second).
"Trail" is time for a trail remains (in second).
"Width" is specified in unit of a width of a screen correspond to "2.0".

The image generated by this function may be hard.
Using "Blue" filer together as necessary may improve appearance.
(Note that "Blur" filter is slow. It may require lowering resolution)


Thunder (Animation)



Generates thunder.
(This composition requires Mac OS X 10.6 or later)
[Interval] is time interval of dischage phenomenon (in seconds).
When the Mix Fader is raised from minimum, always dischage.
In this case, if the Mix Fader is rised to maximum within 0.5 second, discharged at this point (to show as bright as posiible).
If 0.5 second elapse, discharged automatically, regardless Mix Fader position.
[Flash] is time period of blink within a discharge phenomenon (in seconds).
(In the figure, set longer for screen capture, but 0.1 second or so seems to be good)
[Repeat] is maximum count of blink.
Varies randomly from 1 to maximum count.
[Range] is horizontal range where dischage phenomenon occurs.
[1] for spread from left most to right most.
[Radius] is radius of sheet lightning (sheet type light by cloud for example) (a width of a screen correspond to [2.0]).
[Top] is vertical position of top of strike (a width of a screen correspond to [2.0]).
[0] for center.
[Strike] is ratio of strike (cloud to ground discharge).
[1] for strike every discharge.
[Sheet] is brightness of sheet lightning.
[Lightning] is brightness (or thickness) of strike.
[Branch] is brightness of strike branch.
[Image] is illuminated as sheet lightning.
It is effective to insert a [Cloud] (animation) as a filter here.


(Example)


Fountain (Animation)



Generate falling particles.
[Width] is shooting width (in unit of a width of a screen correspond to [2.0]).
[Height] is shooting position (in unit of a width of a screen correspond to [2.0]).
[Pan] and [Tilt] are shooting direction.
[Velocity] is initial shooting velocity.
[Variation] gives random change in initial velocity.
[Size] is a size of particle.
[Speed] is whole animation speed.
If slow, it looks larger scale (height).
[Blur] makes particles hazy.
[Blending] specifies how to overdraw particles (same as [Blending Function] of a layer).

Examples


Waterfall



Hose



Lava


Aurora (Animation)



Generates aurora.
Mimics aurora that occurs around 65 latitude (Fairbanks, Alaska).
(This composition requires Mac OS X 10.6 or later)

[Pan] is horizontal viewing direction.
Pan-90090180
northern hemispherewestnortheastsouth
southern hemisphereeastsouthwestnorth
[Tilt] is vertical viewing direction (0 for horizon, 90 for overhead).
[Distance] is from aurora to view point toward lower latitude (0.1 for 100km).
[View] is angle of view, that is observation range and perspective.
Human eye and normal lens are said to be 45 degree.
The larger, looks like as if captured through wide angle lens.

[Speed] is deforming speed.
[Sway] is deforming width along latitude.
[Fold] is deforming width along longitude.
The larger, looks like aurora break up.

The image generated by this function may be hard.
Using [Blue] filer together may improve appearance.
(Note that [Blur] filter is slow. It may require lowering resolution)

Examples


Looking toward east from under aurora, it is said to look like trailing smoke.



Looking up from under aurora break up, it is said to look like a whirlpool.


Rainfall (Animation)



Generates rainfall.
[Amount] specifies rain drops per second.
[Length] and [Width] are specified in unit of a width of a screen correspond to [2.0].
[Velocity] is falling down speed, [Wind] is side blown speed, and these are specified as move per second, also in unit of a width of a screen correspond to [2.0].


Confetti (Animation)



Generates confetti.
Also applicable to shower of petals.
[Hue Range] is a range of hue variation ([0.5] for whole hue range).
[Rate] is flutters per second.
[Flutter] is angle of fluttering.


Water Surface (Animation)



Represents water surface.
With [Image] input and [Distortion], underwater or surface reflection can be represented.
[Direction] (degree)Flow

-90↓


Celestial Sphere (Animation)



Represents starry sky looking up from Earth.
Over 5000 of fixed stars brighter than apparent magnitude of 6 are shown.
(This composition requires Mac OS X 10.6 or later)



If [Locate] is [(none)], visible area remain unchanged when a scene is triggered.
(changing [RA] and [DE] below also has no effect)
If [Locate] is [Coordinate], visible area is specified by [RA] (right ascension) and [DE] (declination) .
Although normally RA is specified in 24 hour cycle, this composition employs 360 degree cycle for convenience.
RA [hour]Angle [degree]
00
690
12180
18270
24360

Visible area also can be specified by constellation.
(for reference, the Big Dipper (Plough) is a part of Ursa Major)

[Rotate] is rotation around the center of image (merely for visual adjustment).

[Spin] of Earth specifies rotating angle (in second) per second.
(correspond to change of [RA], but this is in 24 hour cycle)
If [0], no spin.
[1] for same as actual spin, spending 24 hours per round.
[3600] is equivalent to one hour, spending 24 seconds per round.

The less [Contrast], the brighter dark starts become, and the less difference in brightness.

If [Shine] is [0], each star is represented as round, and [1] for crossed shape.

[Flicker] and [Rate] are irregular change in brightness, caused by atmosphere etc.


Heavy Snow (Animation)



Represents heavy snow.
[Variation] gives change in [Wind].


Snowfall (Animation)



Represents snow flakes.
[Flakes] specifies average number of flakes generated per second.
[Time] is maximum time (in second) to reach bottom.


Flame (Animation)



Represents pseudo flame.
Brighter area of input image fires.
(black never fire)
[Variation] gives change to [Cooling].
If [Color] is set to black, flame is rendered in shade of approximated color temperature.
Otherwise, rendered in shade of specified color.
(this composition requires Mac OS X 10.6)


Cloud (Animation)



Represents pseudo cloud.
This is the improved version of old [Cloud]
The old [Cloud] is preserved as [Cloud1] for compatibility.

It seems good [Blending Function], [Over] for blue sky back, and [Add] for sunset.

Following pictures are result of above example.

It may be convenient to insert a [Cloud] as a filter composition of [ Image Input ], along with [ Composite ] filter (and [ Fader ] filter if necessary).
[ Composite ] should be set to [Source Over] (equivalent to [Over]).
