Jaycosm🔆I downloaded a significant amount of content from <a href="https://mastodon.gamedev.place/tags/SIGGRAPH2025" class="mention hashtag" rel="nofollow noopener" target="_blank">#SIGGRAPH2025</a> over the past two weeks. In doing so, I noticed an inflection point in the research - a movement from the pursuit of a pure <a href="https://mastodon.gamedev.place/tags/3D" class="mention hashtag" rel="nofollow noopener" target="_blank">#3D</a> simulation approach towards a trend to pursue a Generative <a href="https://mastodon.gamedev.place/tags/AI" class="mention hashtag" rel="nofollow noopener" target="_blank">#AI</a> approach. Coincidentally, today, I decided to see what digital content was available from <a href="https://mastodon.gamedev.place/tags/SIGGRAPH" class="mention hashtag" rel="nofollow noopener" target="_blank">#SIGGRAPH</a> '88, the first I attended, and I noticed these panels on how the nascent <a href="https://mastodon.gamedev.place/tags/ComputerGraphics" class="mention hashtag" rel="nofollow noopener" target="_blank">#ComputerGraphics</a> toolbox was set to impact creatives. History repeats.

Jens KutílekIs there a standard algorithm to create a halftone screen from a greyscale image? How was this even done before computers? I mean like in this image. At 50%, the raster is like a checker board, and at darker tones, it's like white circles on black. So just drawing black circles won't get you there. <a href="https://typo.social/tags/graphics" class="mention hashtag" rel="nofollow noopener" target="_blank">#graphics</a> <a href="https://typo.social/tags/computergraphics" class="mention hashtag" rel="nofollow noopener" target="_blank">#computergraphics</a> <a href="https://typo.social/tags/imageprocessing" class="mention hashtag" rel="nofollow noopener" target="_blank">#imageprocessing</a>
