  • overview of new features included in CUDA 10
  • Multi-Precision Tensor Cores are exposed on Turing
  • CUDA Graphs allow the specification and recording of an execution graph that can be executed multiple times, this reduces overhead and allows the compiler to apply further optimizations
  • interoperability with Vulkan and D3D12 is supported

  • explains how to generate 2D and 3D noise in a Unity shader

  • extends the Metal raytracer with obj model loading
  • a simple diffuse BRDF implementation, including frame accumulation and shadows
  • provides a Mitsuba test scene

  • walkthrough of the geometry pipeline on current GPU architectures and how mesh shaders fit into it
  • description of an upgrade path to mesh shaders
  • look at possibilities of future use cases
  • updated post now includes SM warp-issue-stall metrics
  • previously discussed in issue-26

  • summary of resources for graphics programmers to study and keep up-to-date with the graphics programming community
  • a tutorial that shows how to implement a custom rendering pipeline in Unity
  • implements skybox rendering, culling filtering, sorting and rendering of unlit objects
  • how to improve memory usage and better integration with the Unity frame debugger

  • Unreal released the tech talks from SIGGRAPH 2018
  • Virtual Production in Unreal Engine 4.20, Mixed Reality Production with Unreal Engine, Fortnite: Advancing the Animation Pipeline, Real-Time Motion Capture in Unreal Engine
