So much effort goes into building out huge, detailed game worlds…which get combined with game
mechanics that prevent a casual player from ever seeing most of it. It’s like if you had to pass a quiz to be allowed to see the end of a movie.

Seeing so many bizarre responses to this…the posters sure are mad that thousands of people had well-paid jobs and tons of money got poured into AR/VR tech long after every other company gave up on it.

I’ve sometimes fallen into the trap of thinking that complementing a creative person for their work is less sophisticated or desired than discussion or debate about it but very often the best thing you can say to them is hell yeah and that doesn’t make you dumb it just makes you nice

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

If you have an image model that can generate *any* image, it seems you (to some degree) do actually need to give it an explicit list of all the things you *don't* want. I guess a model that can only generate "good" images is actually not as useful...

A thing I’ll never understand is why a small startup would use a recruiter to try and hire a specific person, instead of having one of the founders/employees do it

There's a new and very neat-looking SIGGRAPH Asia paper on constructing the swept volume based on the path of a moving (possibly deforming) object. Check it out!

absolutely insane the things people are using Python for when there is C#, a language that is better in every conceivable way
I'm such a C# shill but,
any time I hear someone say "the garbage collector slows things down too much" I feel like they're not aware of just how many tools you have to avoid heap allocations
it seems to me whatever work that entails, it's almost always less work than using an unmanaged language
