Oh, I edited my post, maybe this is a read worth.
I thought about 2 states of visibility that can be interpolated.

Cheers

So, if the polygon calculates to 0% strength, it will appear when the slider/animation is at frame 0. If the polygon calculates to 75% strength, it will appear when the slider is at 75% (at whatever frame that represents). And so on.

I hope this is some kind of what you searched for:
Use a spline in the GUI combined with 1 percentage slider to determine the distribution of the visibility.

// within a loop over all points and their vertexvalues  
vertexvalue = GetVertexMapValue(i);  
slidervalue = GetFloat(SLIDER);  
splinerange = GetFloat(SPLINE_RANGEMAP_SLIDER); // A percentage slider defining the mapping of the spline to the vertexmap  
splineX = RangeMap(vertexvalue, minIn = slidervalue-splinerange,  maxIn =slidervalue+splinerange, minOut = 0., maxOut = 1.)  
splinevalue = Spline-GetY(splineX);  
SetPointVisibility(i, vertexvalue * splinevalue)

Here an Image explanation of what I think You mean:

I don't get why a spline is necessary but I've decided that the VertexMap tag would be too difficult for the user to get a clean gradient to cause a cascade as envisioned.

Instead, I'm going to add a tool which lets the user select 'node' polygons and set the percentage value at when to appear. Then I'm going to do the interpolation in code. This makes the user's life happy and mine only a bit more difficult.

Sure. I'm getting close to finishing. Multivariate Inverse Distance Weighting (M-IDW) is the only sticking point now. If you know of any good resources on quick algorithms or code for something like that it would be much appreciated.

I'm sorry, I don't even know what it is
But I take a look at it, sounds kind of interesting.

Got it figured out. Just needed to change a few things to make it work as expected. Should have a video up later today.

Now this is quite what I thought you want to to.
Didn't check the plugin out, yet.
But in the Video, you have an absolute visibilty. (visible or not)
is it possible to set a percentage for this with C++ ?
If yes, why not use a spline ?
At the Moment, if you had used a spline, it would look
like this:

Btw, holy s**t ! Cool Plugin !! O___o
How did you make the Polygons rotate aboute an Edge ?! This is awesome !
