Something new on the Horizon!

Now actually taking advantage of that delta tracking! There were in fact more bugs.

Any closer to the screen and it makes my GPU sing to me😆Gonna work on that next

Nanite Tessellation Nanite Tessellation, aka Nanite Dynamic Tessellation, aka Nanite Dynamic Displacement was the next major feature I worked on after Nanite it...

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming.

You know what else I struggled with? Some silent update that reset my display profile to the manufacturer's instead of sRGB at a critical juncture in my understanding. Ohhhhh my god lmao

Enjoying going through "Physically Based Rendering", implemented with DXR.

The chairs here are participating media using delta tracking, which I hope is finally correct😆

For my holiday break project I’ve been sketching out an idea to help soften the on-ramp for beginners learning D3D12: a header file that (very lightly) wraps the D3D12 API and only exposes the latest/most-useful bits through straightforward function definitions with ImGui-style inline documentation.

I wrote a blog post describing state of GPU market and what does it mean for support of new GPU features

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

I recommend looking at new Paged Out issue #7 - a free magazine with lots of articles, one page each. This one includes my article "Modern 4K Intros on the Demoscene".
