Creating a Directed Acyclic Graph from a Mesh
In this post, we’d like to walk you through the steps of creating a Directed Acyclic Graph, or DAG, that we use at Traverse Research for our in-house rendering framework, Breda, to do mirco-polygon rendering. This is…

Beyond SAH: Building Optimal BVHs
At Traverse Research we are always looking to improve ray-tracing performance. A large factor for optimizing this is building the right and best acceleration structure, usually a BVH nowadays. In the past year, we…

Render Graph 101
Designing an efficient renderer can be quite a tough task. Especially with the new low-level graphics APIs like DirectX 12 and Vulkan where it is now up to the graphics programmer to remove all small inefficiencies.

Bindless rendering: Templates
In this continuation of bindless rendering: setup, we now shift our focus to using bindless resources in shaders. Previously we were using *RenderResourceHandles *to index the descriptor heap, but this still forces the…
