Blending Circle

Today I was viewing the current track and I noticed that it looked too rough, because it is made out of pixels it was looking too pixelated. To solve this problems, I had a couple of solutions, one was trying to make a pixel shader that could help me blend the pixels smoother, the next idea was inserting new verts so that the program would blend it better, and the last idea, that was given to me by my teacher Matt Norris, was to blend the pixels myself when I was exporting the image, that is when I came up with the idea of the blending circle:



Basically the idea is that every pixel is going to be affected by the pixels around it, but the blending needs to happen in an uneven way, because a pixel that is far from the current pixel shouldn't affect the color the same as the main pixel, in other words, the further the pixel, the less it affects the final color, so as you can see on the chart above, there are three sections that affect the final color.

Below you can see a screenshot of the before and after, as you can see the second image looks a lot smoother, it is not perfect, but coming from a 200x200 image, it looks pretty nice.
