Really cool stuff!

Real-time Rendering with a Neural Irradiance Volume
Delivering fast inference (~1ms/frame), a tiny memory footprint (1-5MB), 10x quality gains over probe-based methods @ equivalent mem budgets, bringing neural rendering within reach of consumer hardware without RT or denoising.

Temporal

non-Temporal

Today i added Temporal Accumulation in my GTAO Implementation.

I used Interleaved Gradient Noise as a low discrepancy noise.
I could practically halve the render time, while still having better results.

Here is a comparison with and without:
it's with 2 hemisphere slices and 4 samples each.

Cornell box rendered by ray tracing using the pinhole camera model and the camera model with radial distortion - a comparison.

Want to build your own ray tracer or path tracer on AMD GPUs? Our #Raytracing using #HIP paper covers:

🎇 The essential math
🎇 Camera setup, intersections, NEE, BVH
🎇 How to accelerate everything with HIPRT

I recently read this paper. Interesting idea to use infrared to decompose the lighting terms.

I just released my video about the engine (and game) I've been working on.

The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible.

This is my first YouTube video and it took forever - please repost!

Hello everyone!

I am available for work (full time position/internship) anywhere in the world with priority going to the EU, starting June 2026. 🧵

No Graphics API — Sebastian Aaltonen Graphics APIs and shader languages have significantly increased in complexity over the past decade. It’s time to start discussing how to strip down the abstractions to simplify development, improve pe...

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

What a awesome read!!!!

Ke-Sen Huang has a large batch of SIGGRAPH Asia papers today:
www.realtimerendering.com/kesen/siga20...
Among them: "ReSTIR PG: Path Guiding with Spatiotemporally Resampled Paths" by Zeng et al., which describes a *real-time* framework combining ReSTIR PT and path guiding.

Experimenting with this look for the fractals.

It's GDS Prague Game Jam!

Game Jam progress :)))

C++ code that emits an OBJ file filled with points from voxel edge/SDF intersections.

A collection of vertices in OBJ plaintext format.

A sphere of vertices in Blender.

Dirty gamedev secret: sometimes instead of building proper debug visualizations I just dump the information to OBJ and use Blender to visualize it 😅

But now at least I know my SDF dual contouring is working

I saw some really interesting talks today!

Ive learned a ton about how virtual lights can improve indoor rendering and what the pitfalls are.

This is a great article about ReGIR / World-Space ReSTIR with nice improvements by Tom Clabault:

My talk about ray-tracing is out!

Here I try to explain it in simple terms, while giving some historical context as well.
There is also a quick RTAO implementation with the worst denoise ever here:

feedback is more than welcome!

Bonus post to end the week: If you are a graphics programmer do yourself a favor and get a MIDI board. It makes the work way more tactile and fun. Full props to Matt and @aaronmjacobs.com for getting me on the MIDI train. :)
