- the article presents a rendering analysis of the game Teardown
- shows a look at video captures of the game to develop an intuition before diving into RenderDoc
- shows that the game objects are drawn using a 3D Sprite concept
- the game uses a volumetric shadow map that is updated from the CPU
- additionally covers Lighting, Compositing as well as Post-Processing
- the paper presents how to take advantage of ray tracing hardware for progressive photon mapper
- shows how ray tracing–based collection outperforms hash-based GPU photon mapping algorithms
- additionally introduces Photon Culling, a technique to reduce the number of photons stored per iteration
- the article explains updates required for Chapter 4 of Battle Royale
- shows how increasing triangle counts of the mesh tented is better than masked materials and techniques to preserve vegetation density
- discusses how to handle object animation and improve culling
- the new release introduces support for the Brotli-G lossless compression format
- additionally adds support for RGBA_10101002, R8 and 16-Bit PNG File support
- the video presents how to implement image-based lighting of the Cook-Torrance microfacet BRDF
- contains how to derive the Ground Truth Solution and shows how the Split Sum Approximation can simplify the equation
- presents how to implement the required shaders using GLSL
- the article introduces the idea of expression quadtrees in terms of a collection of square grids
- this allows the space to grow indefinitely as the used spaces change (movement or zooms)

- visually shows how the components combine to form the result
- mentions the difference between rasterization and ray-tracing workloads
- the blog post describes what changes were required to make Lumen work in 60 FPS mode for the new season of Fortnite
- discusses how a reverse lookup structure is used to accelerate per-mesh surface cache information for sharper reflections and lighting when using software ray tracing at low resolutions
- shows how spatiotemporal blue noise was able to improve results from the same number of rays
- the article explains the issue that needed to be solved for Virtual Shadow Maps at 60fps
- explains common issues that are often encountered when trying to cache sun shadow maps
- additionally explains a collection of techniques required to improve performance and quality for the Fortnite art style
