Been deriving some explicit solutions to rendering equation lately for fun, gonna make a new blog post soon 👀

New blog post! Kinda math-heavy this time, but I wanted to share about this weirdly fascinating things called quiver representations that generalize stuff from basic linear algebra to wild unsolvable problems 🤩

@nprofile1q... I mean, like, which exact techniques and new projects are you planning? (assuming you are planning something specific, that is)

After much yak-shaving, I finally have a little template app with: * D3D11 setup, shaders, rendering * Dear ImGui integration * An int64 time class based on NTP * An int64 world position class * A ve...

@nprofile1q... What are you planning to use it for?

Just so I don't have to write all that boilerplate out again. My existing harness was DX9 era, and didn't h...

Still at awe that a relatively simple algorithm can produce such gorgeous rivers 😍

Btw I was messing with river valley generation and it turned out that just removing 2 lines of code makes the valleys look much better! Love it when stuff like this happens 😎

(Yes this should've been a before/after image but I'm too lazy for that)

I don't have true lakes generation yet, but sometimes an "ocean" (heightmap below zero) is generated surrounded by mountains and wooow it does look cool

I've been reading through the modern vulkan tutorial targetting Vulkan 1.3 (http://www.howtovulkan.com) by @nprofile1q... and my thoughts are

1. It's definitely much better than Vulkan 1.0 10 years ago, and
2. WebGPU is a perfect intermediate step for OpenGL -> Vulkan transition

@nprofile1q... Huh, I remember having this exact line of thought at some point :)
"Oh no we're wasting so much...oh it's just 2 bits"

You might remember that I was working on my own programming language a few months ago. I've decided to write a blog post about what this language is, how it is implemented, and what are my future plans!

So I asked students what language/platform they'd want to learn real-time graphics in, and the result was roughly

40% C++
40% Rust
20% Zig

Didn't know Zig was so popular! Also interesting that they don't seem to care about Web at all.

Also, it will be there as long as the host a...

Nikita Lisitsa @Nikita Lisitsa 1777553228

@nprofile1q... Hmm, for tessellation and geometry I think the modern advise is to implement them using compute anyway. Bindless is missing, but I don't teach bindless in OpenGL either 😅 Though afaik there's some effort in standardazing it in wgpu as well.
