Man, I really want to write a book called "The little book of errors" about correct error management strategies and patterns

Not that I know what they are.... but I'd really like to write a book about them

@anyone hating on Rust I bet you won't be talking shit after seeing some 10x developer rust code 😤 https://github.com/rust-lang/rust/...

Holy shit, the exr crate is one of the most overengineered pieces of shit I have ever seen

... well maybe nalgebra is even worse, but that's not a fair comparison. Nothing is worse than nalgebra

Check out this fantastic function: https://docs.rs/exr/1.73.0/...

HLSL, for the love of all that is holy, this is now the THIRD time you made me waste hours trying to debug a shader because of stupid implicit conversions

Turns out that multiplying a float3 by a float4x4 silently truncates the matrix to float3x3, dropping the translation part 😐

Thank you dxc, very cool

I feel unburdened by what has been

Man going from Rust to other languages is making me go insane

Why does no other language have a high quality, standard documentation tool!? I just want to know what classes and functions you have 😭

Reddit is such an echo chamber it's crazy

Just had the realization that the reason why the internet is so toxic isn't really because of anonymity

It's because if you're a massive asshole to someone, that person can't punch you in the face

I mean this for real, and it's kinda counter intuitive, but the underlying threat of violence is what keeps society civil and polite

How does shutting down win11 take 5 times as long as booting it

The license for assets on epics new asset store is insane:

For any Content licensed to you under a Standard License, you may not:
i. attempt to reverse engineer, decompile, translate, disassemble, or derive source code or data from the Content;

HOW IN GODS NAME AM I SUPPOSED TO USE ASSETS I BOUGHT WHEN I CAN'T EVEN DERIVE FUCKING DATA FROM THEM???? Like how in hell am I supposed to load textures and meshes when the only thing I'm allowed to do is to maybe look at them

They DO know graphics cards can do sweet fuck all with a JPG texture, right? Like I /genuinely/ have to translate that thing into a proper format for it to have any use

PSA: All quixel assets are completely free on the new fab store until the end of the year!

If you need any high quality models, make sure to check it out

(why does this read like an ad lol)

Okay so my last idea has one big problem: I need to project vertices into a single space which encompasses an entire hemisphere. AND straight lines need to remain straight when projected.

That's not something a typical projection matrix can do. Damn. I'm thinking maybe something like octahedral projection? [1]

But I'm not sure there's an answer. Else I would have to chop up the hemisphere into parts and try rastering each tri for each view. Ugh, that sucks

[1] https://researchgate.net/figure/...

New idea: Fuck raytracing for global illumination because you just need too many rays for it to converge

What if we do surfels (to keep the number of probes down and relevant to our scene) and we update the 4x4-ish sized hemisphere irradiance maps not by tracing a single ray per frame per surfel. I have a fast as shit compute shader rasterizer... What if I just raster each surfel each frame? Should be around the same number of pixels as the primary visibility so totally feasible....

Each frame just jitter the projection a bit and voila. Should have extremely high quality diffuse global illumination at well below 1 ms. Holy shit this might just work

It just hit me. If you wanna achieve something great you have to dream big. If you aim for something humble, you'll just get lost in the endless land of diminishing returns where you take forever to make little progress

If you aim high, you are naturally inclined to do big strides since you feel that there is still so much left to be done

Just a thought I had working on my engine

Cutie delivery

Tangent space normal maps are going to drive me insane I swear to god

Why can't you just work??? 😭😭😭

There's been talk that UE5's Nanite isn't actually all that efficient (sometimes slower than the alternative) and that kind of got me thinking.

You give developers very high end machines so that they can move quickly. But that doesn't always translate to lower machines. When benchmarking how would you even target lower machines in a simple way? Like for me, I have two GPUs in my system, but one is passed through to a Windows VM. I'd love to test on that GPU but it's just not feasible

All the great test results I (and others) have been seeing might just be a result of the newest cards being insanely fast in relation to cache. Is visibility rendering really faster on a few generation old card? I don't know! Nvidia MASSIVELY beefed up L2 cache on the 4000 series. Does that play a role? Maybe even a big one...

My dumbass thinking it would be easy to get a string value of an exported symbol in a .so and now I'm manually parsing and applying symbol relocations

Diffi-Hellman is actual magic. You can exchange keys over an unencrypted channel and end up with guarenteed unique keys, on which you can start a secure channel

Like how??

PSA: The smaller the compute shader workgroups the more efficient they are, down to the wave size (32 on nvidia). Not exactly sure why, but looks like if you don't need group shared memory always have your workgroups be wave sized

Just this alone gave me a 30%+ performance increase. And combined with a few other changes got me from 50 µs to 10 µs, yay!

Name one thing more fun than atomically writing values into a gpu buffer and them mysteriously vanishing into the aether immediately after the compute shader invocation

I can literally see them in the buffer using RenderDoc and then as soon as I go to the next command the buffer is completely filled with zeros again as if the values never existed

?? like how ??

Visibility rendering using traditional vertex/fragment shaders does 39 million tris in about 3.6 ms

With my newest renderer I can push 314 million triangles in about 6 ms right now

And this is just visibility, factoring in material evaluation of traditional deferred it would be at least like 10x worse. Meanwhile everything expensive about materials is completely independent of geometric complexity in my renderer

Literally me rn: https://youtube.com/watch/...

(cant include image because devrant doesn't want to)

Guess who has to finally swallow his pride and implement traditional deferred rendering with a traditional gbuffer even though he swore to never do that

This guy right here

Nothings going to make you hate reality more than being a graphics dev trying to replicate that

Nothing says "punk" and "against the system" more than having the same political world view as the WEF and Blackrock

The artifical character limit in google notes is so damn annoying

They put actual effort into an anti feature with a "convert into google doc" button. Like they clearly understand one might want to type more than 50k characters, they just dont allow you to do that in notes for no reason besides fuck you

Hey google if i wanted to use google docs, i would have used google docs. Now I just have to split my notes into two because clearly im doing it wrong and google knows better >.>
