I misunderstood the above image when I first saw it. I had originally thought that we were sliding a sort of window down the two Gaussians to see them slowly intersect. I now see it as the 'window' remaining constant, but the center points of the Gaussians moving slowly towards each other. Is that accurate?

I have the question about .5, .4, and .3 in the illustration. Is it the value of (p+q)/2, since that should be the center?

@Parker @tplatina I also interpreted the bottom row as moving a plane to three different positions (f=.5, f=.4, and f=.3), though this does not appear to be the case upon closer inspection. It does appear that the points p and q are moving closer together, similar to the blending of the two metaballs in the top row. (So please ignore the equations f=.4 and f=.3 here, and assume that all three plots on the bottom row are when f=.5.)
