Hi Computer Graphics friends! The most awesome way to show your real-time experiments and projects is Real-Time Live! at Siggraph. Submissions for this year's edition are still open for another week+. Go submit, it's an awesome experience! See you there! s2024.siggraph.org/program/real-t…
I keep forgetting this one. Can you remind me what's the reason that, unlike all other math operations, min(0,NaN) = 0 rather than do NaN propagation? Do you know, @tom_forsyth @rygorous ?
Hi SDF friends, here's a full rewrite about smooth-minimums (soft blends/unions), where I introduce Normalization, Kernels, a circular smooth-min and an analysis of several blend functions. Hope you enjoy it! iquilezles.org/articles/smin/ (new stuff starts about 1/3 into the article)
Something cool happened yesterday - my kid and I played a video game that I wrote 29 years ago, and we had a great time. I wish I could go back in time and tell Past Me what just happened, I wouldn't believe it.
I have my own, but wondering if there is any de facto standard std::vector replacement for "Sane C++" out there? (ie, error codes instead of throwing, indices instead of iterators, doesn't construct/destruct elements, etc) Note - not looking to debate "why not std::vector?"
Submissions for SIGGRAPH 2024 Real-Time Live are OPEN! s2024.siggraph.org/program/real-t… Show a piece of innovative real-time work to a live audience on-stage (art exploration, industrial simulation, research project, creative tool, demoscene, film, game, scientific visualization, ...)
Code is to Data like Energy is to Mass. They are equivalent, but one flows and the other is frozen.

This exemplifies the problem with web dev: I'm not talking about a bloated stack of bad frameworks and abstractions that make apps perform like it's 1980. I'm talking about the developers themselves failing to recognize THAT as a problem and instead tweeting nonsense like this:

It's sad to see great youtubers succumb to the algorithm and ditch infrequent but long content in favor of daily 5-minute videos. Makes the content superficial, and the format frustrating (dilutes this old Xennial's attention). I hate to unsubscribe. The creator economy sucks.
I added Chinese subtitles for my "Painting a Landscape with Maths" video in Youtube, and also uploaded it to Bilibili. Bilibili: bilibili.com/video/BV1Da4y1… Youtube: youtube.com/watch?v=BFld4E…
Talking about directional brushes with @antovsky reminded me of this feature in @QuillSmoothstep . It's often used to create speculars and reflections, and sometimes to control profile contours in line work, but sometimes also more creatively like in this old piece by @gorosart:

There are a lot more trees on earth than stars in our galaxy the Milky Way. That's a lot of trees. But it's also a lot fewer starts that I thought.

@revision_party it is a blast again :) Here is my small (256bytes) contribution for #revision2024 pouet.net/prod.php?which…
My wifey plays Madrigal Seline in @wickedgame Releasing TODAY !!! Who would think we would end up working together on a videogame?? so proud of her incredible job !! @moongamestudios #voiceoverartist Check out her updated Linkedin profile:linkedin.com/in/christina-g…
@iquilezles @amohr This one doesn't fit in a single cache line, yours is better in that respect :-) A right shift and smaller 16-byte aligned buffer
@ProgramMax @iquilezles Haha nice! Turns out you can drop a cache line for the price of a shift. x.com/amohr/status/1…
@MissQuickstep @iquilezles This happens to work! One shift, one cache line. 🤣
Here's my entry: char grade( int score ) { int nIdx = floor(((score - -2.0) * 0.045283969041293934) - (cos(cos(score * 0.03114100715856666) * 1.5790931375763757) * 1.98522506643194)); return "FDCBA"[nIdx]; } godbolt.org/z/77sfs1f8q
I can only assume people proposing dictionaries are trolling, so here goes my contribution to the circus:
@iquilezles Clearly the way to solve this is with a 1-layer RELU network + a linear classifier :-)
building microservices
@iquilezles char checkscore(unsigned short score) { score = (((score << 4) + (score << 3) + score + 54) >> 8); score = (score << 1) + score; return 'F' - (char)((0x6C680000 >> score) & 7); }
@iquilezles Why not just this?
@iquilezles What about def grade4(score): return "FFFFFFDCBAA-----"[(score * 103) >> 10]
@iquilezles @mrdoob With time I realized that it is sometimes worth to let go of some ideas, but pushing ideas that were not so good in the end have led me to my current state which I enjoy :)
@runevision That’s awesome BTW, he references and links to @iquilezles article, but never mentions the video, which is also a wonderful visual explanation: youtu.be/BFld4EBO2RE?si…
@iquilezles That worked so well with the last big tech boon for criminals, kleptocurrency :-)
@sylefeb @iquilezles @BrunoLevy01 @suarezvictor @splinedrive @risc_v @pipelinec_hdl Same thing with 8 bits per channel all the way through :)
@iquilezles @BrunoLevy01 @suarezvictor @splinedrive @risc_v @pipelinec_hdl #Silice version update with animation (racing the beam, pipelined, no CPU). Thanks @iquilezles, looks much more lively now! (Note: banding is due to the VGA pmod being 4bits only, would be smooth in 8bits RGB) github.com/sylefeb/Silice…
Resolved it using ContourPlot3D, and some signed distance fields and "smooth-min" functions from @iquilezles ❤️
@iquilezles @tom_forsyth ARMs fmin/fmax, in default mode, IIRC do give NaN if either operand is a NaN. You can enable an alternative FP mode that gives x86-like min/max, and I think there was yet another toggle? IEEE 754-2008 added minNum and maxNum that treats NaNs like missing data points.
