  • the article provides an overview of the new API that allows users to request the underlying D3D12 resources from an application that is using the D3D9 on D3D12 layer

  • the article proposes a technique that uses a random texture to perturb the normals of dunes to simulate the variation caused by sand grains

  • the article provides an overview of how Vulkan descriptor set management influences CPU performance
  • provides 3 possible solutions to the problem
  • showing how they affect both performance and application implementation
  • suggest a descriptor set caching scheme combined with using a single VkBuffer to store uniform data

  • D3D12 is adding two new flags for memory heap creation
  • D3D12_HEAP_FLAG_CREATE_NOT_RESIDENT, the heap is created non-resident state to enable EnqueueMakeResident to be used for heaps
  • D3D12_HEAP_FLAG_CREATE_NOT_ZEROED enables an optimization that allows non-zeroed pages to be returned

  • the article proposes a solution for voxel rendering
  • voxel scene is pre-calculated into multiple vertical slices
  • each slice is represented by an image and stores all voxel in the slice
  • additionally contains a logic summary on how to procedurally generate a voxel-based island

  • brief article explains how to detect particle overdraw using the PowerVR profiler
  • suggest to disable anisotropic filtering and use close fit meshes for particles

  • the author mentions the new rendering features of Disneys’ Hyperion Renderer that have been used on Frozen 2
  • contains a large selection of stills from the movie
