Bringing Ray-tracing into Remedy‘s Northlight Engine

a brief overview of the concepts of the ray tracing extension
started integration with replacing screenspace AO and shadow map implementations
how to implement ray trace reflections, techniques to reduce noise and optimizations
best optimization advice is to split ray casting and shading
export ray hit information from raycasting shader, and shade samples later using a conventional compute shader
overview of the indirect diffuse voxel solution used in Quantum Break and how ray tracing can be used to improve the results

overview of the Navier-stokes equation, look at each step of the implementation and how it was integrated into the engine
scrollable grid, only run simulation near the player character, a static map for the rest of the world
obstacle injection uses capsule vs. water plane collision checks
algae implementation uses virtual particles that convert density to particles, applies simulations, and turns back to densities

Nvidia sample for mesh shaders using Vulkan and OpenGL
presents performance comparison for different meshes and a varying number of vertex attributes

explains how to implement a shader that simulates a foggy window effect applied to a plane in 3D space
allows the user to clean parts of the window. Foggy state returns after some time has passed

explains how to integrate the DirectX shader compiler (DXC) into the Visual Studio build system (msbuild)
integration of dependency tracking
detecting headers
shows how to provide a regex to integrate with the Visual Studio error window

beginner level overview about consideration for modeling techniques related to performance and minimizing z-fighting artifacts

article with interactive and live tweakable examples
presents a technique that allows constant time conversion from a position on or above a sphere to the nearest triangle index using an octahedron subdivision model

If you are enjoying the series and getting value from it, please consider supporting this blog.

explains how to use new D3D12 API additions to precompile shaders for DirectX raytracing in parallel into a native hardware format

frame breakdown of an interior scene in Ni No Kuni 2
uses a light pre-pass architecture
the cartoon edge line is using FXAA for smoother lines, and the final render result uses SMAA

part 1 of the series on writing a software rasterizer in C++
explains the concept of barycentric coordinates, edge functions and how they are combined to rasterize a 2D triangle
