I have seen that page before - an excellent writeup on how to morph the dither pattern to a sphere and match it to camera rotation to get rid of the dither jank as a character/camera moves through the game scene. But I don't think

It's not just the Canvas API that surprises, it's also how browser JS engines choose to implement those APIs. What works well in Chrome can often cause grief in Firefox or Safari. Working with canvas elements today often feels lik

I thought I had commented on that thread but ... apparently not. Anyway. I built my own hand-rolled dither filter for my canvas library - see the CodePen demo to see it attempt to dither a live video stream (warning: site will ask for permi

When I was searching for a very fast Gaussian blur algorithm to implement into my 2d canvas library, I stumbled across some code[1] which does a magnificent job by using something called an Infinite Impulse Response[2] filter - something th

That second introduction to the TC Lexicon describes - exactly! - the process used in a poetry workshop I attended back in the late 80s[1]. The outcome of each session was also the same, drowning our sorrows in a nearby pub after the meetin

I agree that there is so much to disagree with in the article. For me, the author shot his argument in the foot with this paragraph: > In art, what’s more, the true and the good are unstable. Every great breakthrough in art is rejected a

Excellent that the links can be navigated to using the keyboard. But also sad that when the link text breaks over multiple lines the solution creates a link for each line. Also (I may be wrong): it shouldn't be too hard to make the SVG
