Roads are hard to generate 🫠 But progress is being made 🛣 #gamedev #indiedev #madewithunity

@SoftEngineer Looks great! I think if you sample a downscaled texture you can avoid the gaps in the bokeh kernel

Cinematic DoF with autofocus

@bonzajplc Is true determinism possible over different vendors/architectures?

Attention my fellow nerds :) This video is technical and needs more explanation — but I think it shows interesting implications of where games can go. In BFS I’m running two deterministic GPU simulations inside an asynchronous game. One player controls a jet aircraft attacking a volcano area. I control an undead army using physically simulated projectiles against him. The video shows deterministic fluid simulation, complete terrain destruction, and when the scenario needs it we can reach hundreds of thousands of GPU-computed NPCs in a full 3D physical multiplayer game. The deeper point is that this is very close in spirit to the work @mirror2mask was showing ~20 years ago at ATI/AMD: using the GPU not only to render games, but to actually drive more of the game itself. We are getting closer to making those ideas practical as real gameplay systems, not just demos.

@SebAaltonen I wish there was a way to write custom filters in web

I am debugging why web app is so slow at 6K resolution. Native runs at 700 fps... Turns out that web page had a blur for the background (which was obviously not even visible). These UI blur filters are always extremely slow...

@SebAaltonen GPU culling?

Mini-engine with render thread and new render data model (running on Metal). WebGPU will be running in WASM worker, presenting from there. The main thread is still doing culling. Will move that to render thread next.

Trying out scene voxelisation for reflections - voxelception

Minus the annoying black square bugs, lighting is coming along nicely - here it's running at 1/9th ray per pixel #gamedev

Exploring ReSTIR DI for shadows - not quite there yet #gamedev

@XorDev So basically super sampling?

Single sampling vs 2x multisampling

Sneak peek at the progress on the #WebGPU renderer #voxels #rendering #gamedev

@SebAaltonen How do the shadows work? Love the look (some blue noise in there?)

When I joined HypeHype 2.5 years ago this burger tapping game was popular. Looks better with new renderer + remixed lighting :)

@lisyarus Is it nvidia warp size somehow?

Here's another fun viz. This one is especially cool because you can directly see the GPU warps (little 8x4 pixel blocks) as opposed to workgroups (which are 8x8 here), bit I don't understand why 🙃

@joedixon I want one!

Alright, so I did some Python and managed to render a picture of me. I don't think 1,024 pixels is enough for this handsome face... Still, it's progress

For reasons, I’m finally getting around to working on my office backdrop and I had this (possibly) cool, (definitely) nerdy idea to give it a bit of extra zonda. It all starts here, stay tuned…

@TheMirzaBeig Looks great! Do you just rely on the depth buffer and the light position for this?

Realtime deep shadows for 3D fog (URP). A custom lit, self-shading density field. ☁️🔦 Fire a secondary raymarch in the direction of the light source, accumulating density along the way -> input for material absorption ('Beer-Lambert' law). #unity3d #gamedev

Voxels or pottery? #gamedev

What would attempted clustered rendering be without rainbow nanite debug colours #webgpu

@narrenschlag I have a macbook with an igpu, I will give it a try at some point

@_dan_jackson That's a pretty strong gpu. How do you test for lower end devices?

Found a bug that was slowing things down, so can actually trace waayy more than 64 objects. Here is 768 large voxel models (albeit it does run at about 25fps on my 3070 🤣) #gamedev #webgpu

The beginnings of a G-buffer #gamedev #webgpu

@deusxyz I almost solved this issue a while ago but unity made it difficult - if you can write correct values to the depth buffer from the raymarcher, the triangles will just work

@_dan_jackson ahh yes :o i was thinking its hard to mix in normal triangle meshes tho? :o its very interesting though I want to try it out!

Raycasting 64 voxel objects in a single compute dispatch, each with dynamic transforms #webgpu #gamedev
