Marching cubes experiment made with my own WebGPU framework 🗿🌊 Hope you'll find it fun and inspiring (and satisfyingly disgusting 🫠)!

Very nice. Removed an awkward copyBufferToTexture and now my 3D blurring is even faster! Guess I'm ready to start diving in to marching cubes...

My voxelizer is working! 128^3 voxels < ~150us. 256^3 around < ~800us (on my M1Pro)
Ironically, visualising the voxels is heavier than the voxelizer itself...

125k flocking boids
particle volume shadows
3d fluids (32^3) using hand tracker as cursor
120 fps on M1 pro
Learned a ton doing this project, but I'm bored of particles at this point 😅 Hopefully this will be fun and inspiring to whomever tries this out!

Kindoff getting there! Using pressure makes it more interesting...
Maybe a habit thing, but interacting in a 3D space feels like you need to "master" the interaction which isn't too fun. More parameter tweaking! 🪛

Back at it! Integrating my 3D fluids into my original boid simulation. Lots of finetuning is needed and scaled up the particles to avoid compression 😅 Doing so reveals a fair bit of aliasing...
Also learned that using samplers is not allowed in compute shaders :(((((

Just need some calibration, but the handtracking is doing wonders!
For the Z, I compute a 2D bounding box and use the area as the Z position (far away == sm0l hand, big hand == close)

A few months back I made an attempt to recreate the hiss warp effect from the game 'Control'. Curious to move this exploration to WebGPU...

My hunch was correct. What I thought was working was just seeing my density being diffused...but never advected. *Now* it is properly working 🌊 Time to set up hand tracking as using a regular trackpad is not too exciting...and conveying a higher dimension on a 2D surface makes no sense.

Troubleshooting. Maybe it's my OCD, but had a feeling that my fluids never got properly advected...
Believe this is how it should look like...will continue at a later point.

Yeah it totally works 🔥 Will make an optional projection step as well 🌊 The idea is to use this as a driver for applying forces to stuff

⚠️ strobes and flickers ⚠️
Well...something is happening hah A bit of unlearning to do as I have never done a fluidsim with compute shaders before...
Following along Jos Stam's paper on fluid sims

Yay! Render targets and the ability to create render attachments (MRT's) are working!
And yes, all buffers are destroyed and created anew when resizing.
