Been working on voxel ray-tracing again lately, this time using a BVH2 TLAS and SVT64 (64tree) BLAS(s). The heat gradient in the video shows the step count from 0 to 128. This scene contains 256 voxel dragons, each model is 256^3 voxels :)

Ocean Rendering, Part 1 - Simulation ยท Robert Ryan - Graphics Programmer

A fellow Ocean Rendering enthusiast has written a blog post that goes into the scary math involved with the famous Tessendorf Model and similar implementations. A must read for anyone looking to learn more about Ocean Simulation! Great stuff @rtryan98.bsky.social

Hey BlueSky! I wrote my first ever blog post in a while, talking about how I built my RHI for my game engine Kaleidoscope. Link is โฌ‡๏ธ

I have an abstracted renderer for the most part, with a basic render pass system. I am planning to implement Clustered Forward+ rendering as I find it very interesting. It's currently a forward renderer btw. The code is not too great, but feel free to check it out here:

Sponza running at ~3ms @1080p with 1 Directional Light and IBL

Sponza running at ~3ms @1080p with 1 Directional Light and IBL

Started working on a Vulkan renderer last November but I didn't have much time to work on it due to school. I made good progress lately so I thought I'd share my progress on here since I've been "absent" for a while. I got Sponza running at ~3ms @1080p. 1 Dir Light and IBL, nothing too fancy ๐Ÿ˜„

The water looks nice! What sort of technique did you use? Is it FFT-based, or something more like flow maps?

Yesterday marked the final release of our game, Nakon. It runs on a custom engine, built for PS5 and Windows 10/11. I mainly worked on the rendering, so stuff like Cel Shading, Lighting, FXAA, PS5 backend, Optimizations and much more. You can download the game for yourself here: buas.itch.io/nakon

GitHub - mxcop/src-dgi: Surfel Radiance Cascades Diffuse Global Illumination Surfel Radiance Cascades Diffuse Global Illumination - mxcop/src-dgi

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 :)

Startup claims its Zeus GPU is 10X faster than Nvidia's RTX 5090 280 RTX 5090 GPUs = 28 Zeus GPUs according to Bolt Graphics

This just popped up in my Google News tab on my phone. Looks pretty interesting. I wonder what the pricing will be like.

Cool! What are your thoughts on it so far? I wonder how similar it is to other APIs ๐Ÿค”

Year 1 / Block B completed! Our students worked 8 weeks on a 3D Metal Gear clone, for PC and Raspberry Pi, with their own custom C++ OpenGL ES engine.
Video: Work by Jack Tollenaar. Bullet Physics, skeletal animation, navmeshes, reflection probes and lots more. Amazing work.

Mฮ›X - Surfel Maintenance for Global Illumination A comprehensive explanation of my implementation of Surfel probe maintenance.

I wrote a blog post on my implementation of the Surfel maintenance pipeline from my Surfel Radiance Cascades project. Most of what I learned came from "SIGGRAPH 2021: Global Illumination Based on Surfels" a great presentation from EA SEED :)

It's definitely far from perfect, the main issue being tiling. I have a few ideas already to deal with that, hopefully during the next project :) What's left for the week is to work on documentation and the technical blog post
