My new favorite is this (and this is my last one, promise)

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!

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 (TODO: what year is it?) Fabian Giesen ?

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!

Did I ever say that I love math?

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:

BoundingBox.update()

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.

Talking about directional brushes with anton mikhailov reminded me of this feature in Quill by Smoothstep . 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 Goro Fujita:

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.
