Is it possible for you to provide the Falloff function for the square falloff equation?

Good catch! I’ve updated the article with the correct equation. Thanks!

Thank you very much for the tutorial.
I recently heard about metaballs, and I immediatly loved them.
They are such an easy way to create a very cool effect, and thanks to your tutorial I really understand them perfectly now.
There’s one thing I wanted to note though:
Here in the tutorial you are using (2/3)(1-r)(1-r)
But in the demo you are using (3/2)(1-r)(1-r)

It should be (3/2), otherwise you won;t see anything.
You might want to fix this 😉

I’m not sure what I was doing wrong but I started over and it works now. Thanks again! ]]>Aquileo | By: Jeff http://nullcandy.com/2d-metaballs-in-xna/#comment-623368 Wed, 09 Jan 2013 06:47:50 +0000http://nullcandy.com/?p=210#comment-623368Hey thanks for the great article. I have a question though. I’m trying to restrict the metaballs to a rectangle inside the viewport. So instead of detecting when the balls hit the viewport bounds, I’m trying to see when the hit the rectangle bounds but the balls bounce off walls that seemingly arent there. What I mean is, they stay in the lower right part of the rectangle as if I had drawn the rectangle there. I suspect it has something to do with

effect.Projection = Matrix.CreateTranslation(-0.5f, -0.5f, 0) * Matrix.CreateOrthographicOffCenter(0, viewport.Width, viewport.Height, 0, 0, 1);

Can you let me know what I can do to keep the metaballs inside the rectangle? Thanks again!
