Uh oh! In that case I must be doing something badly because I'm getting worse aliasing than you, with more advanced interpolation ๐
I was getting it so bad I even tried windowed sinc AND oversampling.
Back to the drawing board then.
Edit: Fixed it, thanks that was helpful to know. I'm getting almost no visible aliasing now. I can probably back off it a bunch. No wonder I couldn't find any articles online about antialiasing samplers. I was surprised if it was such an issue xD
