Press space to convert. This is pretty slow, even on turbowarp. Please be patient lol. USE TURBOWARP: turbowarp.org/1243081215/. If you don't wanna wait like 30 seconds (you still might have to for interpolation method 3). There are three interpolation methods used: 1. Bilinear (smooth but loses quality, also fastest) 2. Bicubic (better quality, but not good for fine details) 3. Lanczos (best for fine details, slowest). The greater the kernel size, the more accurate. I found a kernel size of 3 or 4 to be best
Uses the atan2 function from @raucket Uses binary image scanner from @griffpatch Use with credit if u want. Btw image must be equirectangular (2:1 aspect ratio). This is probably usless tbh as online converters exist but I think its cool tbh
