First step for old school global illumination : Cubemap rendering.

🎨🤖 Oh, look! The latest from the "we're too cool for physics" crowd: a #neural network that allegedly renders triangles with "global illumination"—whatever that means. Just what we needed: more AI-generated images of stuff no one asked for. 🤯🖼️

RenderFormer: Neural Rendering of Triangle Meshes with Global Illumination

Alla fine, ho optato per #BabylonJS.

Per quale motivo?
1. È una libreria interamente scritta in #TypeScript.
2. Ha già un motore di rendering stabile basato su #WebGPU.
3. Offre nativamente alcune funzionalità molto interessanti, come la #GlobalIllumination e la gestione della fisica #Ragdoll.
4. Include il motore fisico #Havok: usato anche nei giochi AAA.
5. È ben documentata e con molti esempi.
6. È parecchio mantenuta, con nuove release e fix ogni pochi giorni.

Managed to get the luminosity criteria working, which makes the denoiser much stabler when moving the camera.
However, now the low-light situation is more grainy😭 .

Cool thing is, I managed to half the GI-trace render time by changing the GI-Cache layout (from linear to tiled with the same size as my work-groups are). So that's a win 👍 . I'm now at 12ms - 14ms for a 3 bounce trace, at 3440x1440 for the GI pass.

#BLOG day! This week, we’ll take a look at how to render caustics using photon mapping.

Proposed by Henrik Wann Jensen in 1996, photon mapping is a global illumination algorithm that shoots out photons at light sources and store their scene interaction information in something called a “photon map”, to be reused later in the calculation of indirect lighting.

Please check out the blog post if you are interested! https://blog.42yeah.is/rendering/2023/05/13/photon-mapping.html

there, fixed that, fixed some of the unwanted blooming there was going on, and added some noise to the GI layer to prevent banding

looking really good now, i think! here's a gif toggling between GI and no GI

and just as a reminder, this is all sprites :3

How does one get the inside of a building lit in Unreal Engine 5?

It seems even with all the screen space GI and glossy floor and extra-bright sun shining directly through windows deep into the room, my rooms remain in almost complete darkness...
