I've been reverse engineering & decompiling Worms: Armageddon (into Rust!) for the past 3 weeks. So far I've replaced about a 120 functions and made a lot of tools, but I'd like to turn this into an OpenTTD/RCT style project soon-ish, with multiplat support as a very long term goal.

One thing I've learned while writing a voxel engine is how huge the difference between "realistic" and "worst case" can be. With the same render distance, a typical hilly landscape uses about 2MB of VRAM, while a 3D checkerboard pattern uses over a gigabyte. Yup, that's three orders of magnitude!

And here's the current state, about 1 week after the initial commit. Ambient occlusion had a huge impact on the visuals.

There comes a time in every developer's life where they just have to write a voxel engine. This one is using #rust, wgpu and GPU driven rendering. #graphicsprogramming

I've continued working on my little 3D engine based on wgpu and #rustlang. This week I managed to implement fully GPU driven rendering. The engine gives the GPU lists of drawables and meshes, and compute shaders perform AABB culling and generate indexed draw commands. 17K objects in about 0.03ms.

WESL advertises wgsl-analyzer as the official language server (or at least as a potential solution), but it doesn't actually support WESL from what I can tell? github.com/wgsl-analyze...

wgsl-analyzer provides autocompletion & syntax highlighting for VS Code, but doesn't support the same import syntax as naga_oil (even though it has some Bevy-specific features [which will be removed because of WESL migration?]) So I have to live with non-actionable errors in my IDE.

I'm working on a shader playground / 3D engine skeleton in #rustlang with winit, wgpu and naga_oil. About 1.5k LOC, has shader hot reload and very basic GLTF support. The DX is better than in my previous WebGL-based engine but the ecosystem is not yet very mature / stable.

Great catch! I had a look at this, and it is indeed powered by quest-specific scripting. When Glarthir's quest-related travel packages finish (= he reaches the victim), the script checks if the player can see Glarthir. If not, the victim NPCs are scripted to die.
