@LeLocTai I'm still planning to use (H)RC for Indirect Lighting, but for Direct Lighting I think it's nice to have something more "controllable". For example it's difficult to make spot lights using pure RC.

I've been improving the cone traced shadow quality using anisotropic occlusion. The idea is to store occlusion values for each of the four cardinal directions (-x, +x, -y, +y) in the 2D case. We interpolate those based on the cone direction. Here's a before and after image:

@Gikster007 It's the flash light that does it hahaha

Experimenting with cone tracing in our 2D pixel art game :) In this video I am using cone tracing to trace the soft shadows. (no GI *yet*)

During the past week I dove back into Radiance Cascades, this time Holographic Radiance Cascades. It was really fun to again dive into this and make my own implementation of it, running entirely on my CPU. This demo contains no explicit light sources, only emissive pixels! :)

@tran_thuc97537 We didn’t have time for it, we have dynamic AO with IBL instead. Because the levels are very open it works really well :)

We've used the voxel game-engine we build as a team of students to make a little diorama puzzle game :) This has been an very fun experience, building from the ground up, working together with designers and artists! Game: buas.itch.io/zentera Engine: youtu.be/uvLZn1X_R0Q

A big optimization I worked on after my last post was making our voxelizer *lazy*. So, it only updates parts of the scene that changed. This made a huge difference for our performance and allowed us to push for larger level sizes! Below is a high-level drawing of how it works:

The engine supports both PC and PS5 through a platform-agnostic render graph I wrote. It was a big gamble, I had written it as a prototype in 2 weeks, but it really paid off in the end. Saving us a ton of time and keeping our renderer clean :) Code snippet showing the interface:

@Passer1dae Very impressive quality!

Here's a video showcasing the demo we created using the engine, to showcase our engine is capable of being used to make actual games! :D

The past 8 weeks I've been working in a team of fellow students on a voxel game engine. I've been primarily working on the graphics, creating a cross-platform render graph for us, and working together with @ScarakLynn on our cone-traced lighting, and various graphics features! :)

Here is a showcase of my voxel physics with destruction inspired by Teardown. I'm very happy with the state it's in currently.

@ChopperLin89 @thefranke That’s ray tracing single shot diffuse global illumination, I’d argue that’s not an unexpected time. You can temporally amortize by shooting 1/4 or 1/8 of the rays per frame. There’s probably also still room for optimization in the ray traversal algorithm I used.

I decided to open source my implementation of Surfel Radiance Cascades Diffuse Global Illumination, since I'm not longer actively working on it. Hopefully the code can serve as a guide to others who can push this idea further :) github.com/mxcop/src-dgi

@bendzzArt It’s quite difficult to explain RC in a Twitter message hahahaha There’s quite a few resources on the topic out there if you’re curious to learn more about it. Including my own article m4xc.dev/articles/funda… which focuses on the fundamentals in 2 dimensions :)

@bendzzArt Radiance Cascades in 3D usually is done by evaluating radiance only on visible surfaces. Because going full 3D grid is very memory intensive. In this case I’m using Surfels as a way of placing those surface probes, and making them temporally stable.

After working on the voxel destruction I'm happy to show my progress. I can break objects in any shape with working voxel physics in real-time.
