Author here — I apologize for that; it's on my short list of things to fix. I actually hadn't fully understood that the "Ctrl+" zoom in desktop browsers shrinks the viewport rather than doing an actual zoom (unlike pinch

And it's crazy to think that during that decade, GPU functionality was changing pretty rapidly. So, you really are aiming for future GPUs that don't exist yet as you develop the tech. Of course, the trajectory of GPU advancements

I think the SIGGRAPH talk you referred to is: "A Deep Dive into Nanite Virtualized Geometry" ( https://www.youtube.com/watch?v=eviSykqSUUw ) There's also this short high-level intro (2.5 min) that I thought wa

Excellent list; I like the pragmatic and down-to-earth explanations. No buzzwords, no "microservices" (: I'd say that a good amount of this advice also applies to one-box systems. There can be lots of kinda/sorta distr

Hello, fellow artist+programmer (: What do you think of the quote: "Whatever you do will be utterly insignificant, but it is very important that you do it" ? Personally, I think playing with little dreams is beautiful, but I do ho

I like Valgrind, but day-to-day, I find myself typically reaching for Sanitizers[1] instead (ASan, et. al.), especially since they're built-in to many compilers these days, and are a bit faster IME. Are there any use cases that people

That's pretty similar to what I'm doing! The CPU builds an RPN expression (like "circle, square, union, triangle, subtract"), and the shader evaluates that in a loop. I wasn't able to find examples of other people d

Am I right that the output of the lisp code is ultimately a plain GLSL shader (like one might find on shadertoy.com)? I built a SDF-based rendering system (2D) for my game, and one of the big hurdles was how to have them be data-driven, rat

Fine I'll bite :Þ Have a poorly-ordered braindump: In my life, I've kindof developed a rule of thumb: if it's the more difficult path, it's probably the better path. That heuristic isn't always correct, but I find i

This article summarizes some takeaways from Stonebraker's paper “What Goes Around Comes Around…And Around…”[1] For those unfamiliar with Stonebraker, he's a luminary in the DB field[2]. 80 years old and still very active (: [1] h

Always glad to see articles discussing an emotional side of software development (: I do disagree with this claim (though later points temper it a bit): Why is it important to share your work with the world? First, because there'

For those interested in such topics, I'm a fan of the "Oklab"[1] color space. It's not perfect, but well documented and discussed, has freely-available implementations, efficient shader code, etc. and overall works prett

Lua has its own built-in low-level serialization, in the form of string.pack() and string.unpack()[1]. This is akin to Perl's pack()[2]. But note that this is a tool used for laying out bytes in a certain order (like a C struct), not a

Oh absolutely. I have no objection to the approximation. I have an objection to the shoddy reasoning put forth in its favor. If they said "0.5 degrees is small enough to ignore in this case" that would be fine. But instead they gi

I am perpetually annoyed by the argument "the Sun's rays are parallel" made here and many other places. They tell you to take a single point on the sun, and draw a big skinny triangle from there to different points on the Ear
