Well, here’s my final follow-up to the dithering stuff.
I actually grew a bit weary of fiddling with it, so pardon me that this post won’t be long. This will also be my last one about this, too… read more »

ABS(x1 – x2) + ABS(y1 – y2) + ABS(z1 – z2)
This would remove the need for the costly multiplication. Whether it still looks good is a thing to try out. Which I did, and it does. read more »
