My experience is that the ecosystem is a mess, have hit winit, wgpu, and countless bevy bugs, iteration times are abysmal, documentation is nonexistent. In the time it would take m…

You absolutely cannot implement stream compaction “at the speed of native” as WebGPU is missing the wave/subgroup intrinsics and globally coherent memory necessary to do that effic…

Really lovely. A lot here reminds me of design in Odin lang. Short integral types, no const, composite returns over out params. Big fan of the approach of designing for a single tr…

Odin is lovely and a great fit for graphics and games programming. I’ve been doing my real time graphics research in it (the CPU parts at least).

Absolutely! On a related note, looking for C development jobs is a real pain for this reason.

I personally find the experience of writing GPU compute code pretty nice on graphics APIs. The interface is pretty much the same “dispatch a 1-3D set of 1-3D work group indices”. T…

For 3D, use a game engine. Unity, Unreal, maybe Godot depending on your perf requirements.

When you look at how much nicer the programming experience is for something like Metal it’s hard to blame them. Think I’d prefer to write 3 backends for Metal level complexity APIs…

If someone wants to get into graphics API programming that’s probably a bit too high level, as lovely as it is.

I know you mean major desktop platforms, but in terms of market share for real time 3D applications, mobile and console dwarf Mac and Linux.

Not faster to integrate it into a build system or compile it though.

I suspect (1) is just because Dear ImGui is BYO graphics backend, so it doing lots of clever texture management stuff for lots of images would increase the surface area of that int…

Dear ImGui certainly seems more popular wherever skinning isn’t a priority (though I’ve seen games use it even for user facing UI). It’s become a bit of a Wilhelm scream, love spot…

Odin is probably the most productive I’ve been in a language. I went from reading the docs to having a working interactive PBD particle sim in VR via OpenXR in around 48 hours wall…

This is completely wrong, the digital art industry is enormous and, mind you, pretty uniformly pissed off that this model has been trained off of their non public-domain work.

Another interesting factor. PhD stipends are getting gobbled up by inflation. I wonder how many people will forgo starting a research career because they want to be able to pay ren…

What are your egress charges?

Why not all of the above?

Also worth pointing out that Bayesian methods are the only good option when performing data assimilation into large scale simulators (like epidemic models) which are typically stat…

Bayesian statistics gets tonnes of practical use. Software packages like STAN-MC get lots of use in traditional stats/econometric circles, while probabilistic programming languages…

As someone about to pause an industry career for a PhD, I still think this is good advice!

That last one is a good point. The size of the “sweet spot” in an HMD isn’t discussed enough.

Quest 2 can overclock to 120Hz can’t it?

Oculus is leading the pack in wireless by offering Airplay out of the box. I’d wager that’s part of their vision too. Also the UE5 demo running on a PS5 doesn’t mean that it could …

Even as an enthusiast (5 headsets and counting) I have to agree. There have been several month periods where I didn’t use VR due to driver instability. That being said, body tracki…
