mcjCycleFilter was initially created to filter/smooth cyclical animation curves.
then were added the ability to
- use your mouse to directly edit the curve
- synthesize the curves from mathematical functions
- repeat, slow down, speed up or delay an animation
- January 4th 2013 fixed crashed-inducing problem when a figure's root node was selected
- march 17th 2012 fixed for daz studio 1.8 compatibility ( no prop.isSelected() )
- Jul 27, 2011release
A Zip file containing the script(s) can be found at the bottom of this page, in the "attachments" section
Unzip this file in your Daz Contents folder, typically this means c:\program files\daz\studio\content.
Once installed you will find the script in your library, in Studio/scripts/mCasual
mcjCycleFilterDS2.ds is for Daz Studio version 1.8 and 2
mcjCycleFilter.dsa is for Daz Studio version 3 and 4
important note: mcjCycleFilter is a script, not a plugin.
Like all scripts it tends to do its work rather slowly.
So you will want to use it on short animations.
It was created for cycles, like walk cycles and dance cycles
Select a node in your scene, example, i selected Aiko3's right foreArm
et the PlayRange (Timeline tab ) to a short span of time, ex: frames 0 to 30
by left-clicking on its icon in Studio/scripts/mCasual
| VIewing / editing the "Current Values" curve
in the upper right corner, select one of the properties of the foreArm, i selected Bend
in the lower left corner of the screen you can see that the source selected is "current values"
in the lower right corner of the screen you can see that the Input Range covers frames 0 to 30
all this means : the red horizontal line shows us that Bend is currently at 0 degrees and stays 0 degrees from frame 0 to frame 30
the red square indicates that Bend has a keyframe at frame 0
in the upper left corner you can see "Bend - Current [-1 1]"
so for points on the curve at the bottom of the plot Bend is at -1 degree and for those at the top Bend is at +1 degree
when "Source Selector" is set to "Current Values" you can use your mouse's right button to add key-frames and you mouse's left button to delete them.
| Time-shifting and Time-stretching a curve
in figure 2, the selected source is still in current values
Input Range goes from frames 0 to 30
we can see that the Bend angle varies from 0 to 90 degrees,
Aiko is bending and unbending her arm,
this all happens in 1 second since the frame rate is 30fps.
but this time the Output Range is not identical to the Input Range, instead i typed new values so that it covers frames 30 to 90
if we press the "Apply" button, mcjCycleFilter will do its magic !
Notice that after i pressed Apply, i changed Input Range to [0...90]
and we can see what happened
the animation curve that existed from frame 0 to 30 was copied ( time shifted ) to frame 30 and was time-stretched to cover 60 frames or 2 seconds
| The built in synthesizer ( mathematical functions )
Instead of working on the existing animation curve you can build one from scratch using mcjCycleFilter's built in synth.
Turn it on by clicking "Synth" in the "Source Selector" box.
the func drop-down-list lets you chose a mathematical function
|Available functions in this version
- Smooth Step
Min and Max let you specify the amplitude of the swing. For Aiko's right ForeArm, we could use Min = 0 and Max = 90
angles are reversed for the left ForeArm, so we could use Min = -90 and Max = 0 or Min = 0 and Max = -90
Phase lets you shift the curve while maintaining perfect looping. A Phase of 90 degrees shifts the curve by 1/4 of the curve's width.
A Phase of 360 degrees shifts the curve by the full width of the curve ( and is in fact a waste of time )
Cycles will make the function repeat a number of times.
The first func in the list is named "current" allows you to shift, amplify/attenuate or duplicate the existing animation curve
