Does any one have a link to a perfect circle, I'd love to see if it has the proposed effect on me.
- titzer 3y agoLook at a coffee cup.
- TeMPOraL 3y agoHow can I distinguish between errors of perception, errors in manufacturing, and errors of perception of the designer who eyeballed circles on a computer screen with non-square pixels?
- InitialLastName 3y agoWith a coffee cup, you should be able to take a micrometer (or a piece of string) and verify roundness of the base object to whatever arbitrary precision your heart desires (and your reality will allow).
- TeMPOraL 3y agoI don't think I've ever seen a coffee cup that would let me do that. As I said earlier, I don't really trust their roundness, and that's on top of them usually being made of some kind of ceramic and thus having grain. (Maybe a cheap, single-use plastic cup would be smooth enough and stiff enough and round enough, given the production process.)
- ks2048 3y agoYeah, I don't know what effect he is talking about here. SVG has <circle> which I would assume is normally rasterized to pixel-level accuracy (as opposed to approximated with beziers), so there are lots of "perfect" circles to be found. https://developer.mozilla.org/en-US/docs/Web/SVG/Element/circle https://developer.mozilla.org/en-US/docs/Web/SVG/Element/cir...
