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

After quite a bit of work, I am finally done with the first blog post about ocean rendering! You can find it here: rtryan98.github.io/2025/10/04/o...

I've also decided to create a video to showcase the ocean simulation in motion: www.youtube.com/watch?v=0OXm...

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome!

Crazy how fast time flies by.. For me personally, the ability to do shader prints and validation once bindless was in place, was probably one of the biggest QOL improvements I could've ever dreamed of ๐Ÿ˜„

Ten Years of D3D12 For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.

(And yes it's really been 10 years ๐Ÿ‘ด).

Back in 2021 I released a Vulkan sample that demonstrated adding ray-tracing to a traditional game render pipeline. Since then the code has rotted away and stopped working. So this week I finally resurrected it! Hope it will keep being a learning resource for beginners.

The Breda framework ๐Ÿฆ€ utilizes feature toggles for the configuration of most systems๐Ÿ—๏ธ. In this video, we take a look at the โ€œray-traced-reflectionsโ€ feature toggle ๐Ÿชฉ. We use it to enable or disable the reflections in our renderer. First we use the web interface, then the configuration file system.

The render graph debug composer is an essential component of the Breda framework. It allows us to view any resource we use during render graph construction ๐Ÿ—๏ธ. In this video, we select a few textures which are used while rendering our final image.

Bindless renderingโ€Šโ€”โ€Švalidation With a bindless rendering pipeline in place as covered in the previous blogs bindless setup and templated bindless, we are now faced withโ€ฆ

I've updated links in all of the bindless series post, as well as included a small segment on "we've got bindless resource bounds checking at home!" Buffer bounds checking specifcally was super worth it, as this surfaced quite a few unnoticed bugs.

Huh, TIL. The "transform normals with inverse transpose matrix" is not ideal, turns out. Adjugate matrix is both better and faster to calculate. See github.com/graphitemast... and shadertoy by iq himself: www.shadertoy.com/view/3s33zj

I'm keeping updated this super comprehensive collection of <Light Transport> papers (by tech and by year), from the Kajiya eq to latest differential and neural approaches, passing by RRT and MC theories | As before, repost if you think it may be useful to others.

Our entire bindless abstraction for both vulkan and dx12 is built on templates, and has been running very stable for quite some time already.

First steps of a workgraph path tracer, already beating a naive pipeline-based path tracer in terms of performance. Still long ways to go before getting in the ballpark of a wavefront PT.
A major painpoint is definitely having to generate nodes due to recursion being a bit limiting.
