The purpose of this shader is to apply magnification, whirl, and mosaic effects to an image within a specified circular region, allowing for dynamic manipulation of the image's appearance through adjustable parameters.
For Project 5, I started with a simple vertex and fragment shader, very similar to the one provided for the background in Project 4. Once I verified that the image loaded, I started working on separating the ‘lens’ logic from the rest of the background. I eventually got a grey circle in the center of the background, so I knew my code was working. I started implementing the zoom and swirl effects from there since they were a little simpler. Once I got those two working, I was having trouble getting the mosaic effect to work, but then I realized I was using the same variable twice when I should have been using one with a similar name.
