trying to make random stuff to test my voxel engine

Custom sun position and procedural sky box for my #voxel engine. Added this to the single compute shader the engine runs which has now 900 lines of code - which is starting to get a bit ridiculous

My Slang shaders are about 10% faster when compiled to spirv with -O0 rather than -O3 😭 how

Miolith @miolith.bsky.social · 20/06/2026

I don't know anything about voxel terrain generation so I just throw in a bunch of random formulas and see how it goes

Today on 🚀 blazingly 🚀 fast 🚀 voxel editor ™️ we're editing blazinglion voxels 🚀 in real time featuring humongous ellipsoids The trick is that the dynamic ellipse you see when I drag my mouse is just a raymarched ellipse SDF that I render as voxels by clamping the ray to the nearest voxel position

Miolith @miolith.bsky.social · 24/05/2026

Found this idea of recycling empty voxels in dense voxel grids to store the distance to the nearest voxel in each of the 6 directions. With this new addition to my engine I can now have real time brute force path tracing at reasonable framerate on my 10 yo dusty GPU

Miolith @miolith.bsky.social · 29/04/2026

Decided to raytrace everything in a single compute shader in my voxel engine, it's just easier to share light data between static world grid and dynamic entities like that The entities are just a 3x4 matrix transform and a 3d texture. I first ray intersect their AABB and raymarch the 3d texture.

Miolith @miolith.bsky.social · 23/04/2026

Added the undo feature to my voxel editor. The undo history has only a depth of 1 for the moment because I'm not sure how I will handle a history of dozens of voxel grids on the GPU yet

Miolith @miolith.bsky.social · 18/04/2026

Adding entity modeling to my #voxel editor. Entities are 3d textures rendered with fast voxel traversal and the editing process is 100% compute shader as I found that fast and convenient. I'm just really apprehensive about the moment I'll have to implement the Ctrl+Z feature.

Experimenting with compute shaders editing that 100x100x100 3D texture 🥸

Miolith @miolith.bsky.social · 12/04/2026

I believe it's common in c++ to implement your own span<T> type to have a std::initializer_list constructor (unlike std::span), but I also like to have a span<void> specialization that allows any span type to be passed as an argument without bothering with templated functions

Miolith @miolith.bsky.social · 10/04/2026

Added moving voxels entity to my engine. This is a cube mesh rendered with a fragment shader that casts ray on a 3d texture. No idea if this is efficient I just copied the idea from Teardown

They don't want you to know but this trick makes your app 10x faster

I still don't know how lambda captures work in C++ so instead i'll stay ignorant and just do this

I hope you all enjoy my assert macro. In debug mode it shows the stack trace and add a debugger breakpoint. In release mode [[assume]] allow the compiler to optimize based on assumptions about the program's state. Don't let people tell you this is a UB hazard, you should push that to prod NOW

Just resumed working on that voxel editor from scratch in C++/Vulkan. Since last time I added - Painting over voxels - Mouse raycasting Quite happy with the performance despite the whole voxel 64-tree being sent to the GPU at each update #voxel #vulkan #c

Another screenshot of my voxel editor. The voxels are very cheap to raymarch so it wasn't hard to add shadows

That voxel editor starts to look quite good ☺️ #voxel #computergraphics #vulkan #c

Miolith @miolith.bsky.social · 06/07/2025

Working on a real time voxel editor to edit the world of my game that has a ton of tiny voxels I implemented this in Vulkan & C++ because I presumably enjoy torturing myself and I use a sparse 64-tree to store the voxels + raycasting in a compute shader for rendering. #voxel #computergraphics

Just found a cool formula to add tiles, goosebumps or spikes to any surface so I made a whole shader out of it www.shadertoy.com/view/lc3yRr

Are there any Outer Wilds enjoyers here ? Well, I made this shader specifically for YOU and definitely not because I only knew how to render spheres at the time!!! Source code : www.shadertoy.com/view/lcXGWs

If you are, or know, a beginner in computer graphics, I'll let you know that I made this nicely animated video about why those pesky APIs want you to use 4D vectors to do 3D geometry www.youtube.com/watch?v=o-xw...
