Here is what I have so far\u00a0https:\/\/comp-photo-book.pages.dev<\/a>“<\/p>\n\n\n\n So, you’re saying, “why bother looking at that<\/em>?” The main reason, for me, is: interactive figures! I missed the memo, but it turns out SVG figures now support interactivity<\/a>. <– And that link is wimpy, mostly showing highlights when you mouse over or click something. It’s better than that… The process of making an interactive illustration is imperfect. In this case, the original figure had a bug for some values on the slider, which Fredo then had to get the AI to correct. I’m sure there are plenty of other bugs throughout the book at this point. Fredo says it’s “very much in progress and I have more or less not read a word of it.” But, having an AI agent code up interactive SVG figures is way more efficient than learning a whole new language and dealing with all the fiddly bits.<\/p>\n\n\n\n The book is indeed incomplete, many sections TBD. It has layout problems and oddities, like some equations having unnecessary scroll bars. But, it’s an experiment, WIP, and it’s notes for a class – an effort that, if done by hand, would have easily taken a few authors a year or more. Perhaps consider it an exercise: maybe reward students with a candy for each bug found? Well, that’s a bad idea, I admit: a bunch of students then are learning the wrong material before it’s corrected. That said, I’ve heard of teachers having students use AI tools to help find and correct errors purposely put into some document or code. For this sort of book project, the fact-checking is probably the most time-intensive part.<\/p>\n\n\n\n To digress a bit, here’s a paragraph from an article in Wired<\/a> about fact-checking that made me laugh: “Then there\u2019s the models\u2019 own assessments. When I asked ChatGPT how accurate the major LLMs are, it told me that most models had 90 to 96 percent accuracy on some professional-style tests. It then offered a link, confusingly, to a paper on a sleep medicine certification exam. On ‘general real-world questions,’ it simply offered me the rate at which models like it have been shown to hallucinate: 1 to 2 percent, apparently, though when I tried to click through to that referenced source, it didn\u2019t exist.”<\/p>\n\n\n\n Back to the coolest part of Fredo’s experiment – the figures. The aliasing page has a few – scroll down. Or go here<\/a> and play with shading models (this figure could use something to normalize the curves, but in a way, that’s the lesson). Or warp a mesh<\/a>. Or check out caustics and chromatic aberration<\/a>. Or look in other chapters – you’ll find them. Fredo notes, “It’s crazily easy to make demos. I was initially worried that figures were going to be a major issue but they turn out to be mostly easy and incredibly fun. I even have stable diffusion running\u00a0in the browser.”<\/p>\n\n\n\n I know of only one other book related to computer graphics with interactive elements: Immersive Linear Algebra<\/a>. It seems like there should be more, but I can also imagine how much effort it is, or was, to make such figures (I know my MOOC demos<\/a> took me a good long while). Hopefully now with interactive SVG and AI agents, there will be.<\/p>\n\n\n\n
Go to the section on aliasing<\/a> and check out the first figure. Slide the slider – ooo, high frequencies turning into lower ones, in a nutshell. This figure, and all the others, were generated by AI, with Fredo’s guidance.<\/p>\n\n\n\n![\"\"](\"https:\/\/www.realtimerendering.com\/blog\/wp-content\/uploads\/2026\/07\/aliasing.png\")
