How We Render Extremely Large Point Clouds

  • the article discusses a system to compute shader rasterize large point cloud datasets at interactive rates
  • the detailed blog presents how they solved problems along the whole pipeline
  • covering point reordering, point rejection and hole filling, level of detail selection and calculation, as well as memory usage optimizations
  • additionally presents how the data is expressed and used from the Unity implementation

How do I become a graphics programmer? - A small guide from the AMD Game Engineering team

  • the article gives some advice on how to get started with graphics programming
  • discusses the complexity of different graphics APIs
  • additionally provides a list of tutorials/blogs and courses that provide a good starting point

(Graphics) Programming Resource List

  • a start of a collection of books and resources for (graphics) engine programmers that I recommend
  • covering mathematics, engine architecture, graphics programming, collision detection, software design, as well as knowledge organization

GM Shaders Mini: Phi

  • the article presents Phi and the Golden Angle
  • shows how to use these numbers for a point distribution in a rectangle as well as a disk
  • provides a shader toy example to present the effect when using blur kernels


Principal Graphics Programmer

Remote, United Kingdom

Studio Elevation are re-establishing the boundaries of VR. We’re looking for a talented Principal Graphics Programmer to help us explore, create, and deliver world-leading innovation in software and VR hardware.

Interpolating Color Image Histograms Using Sliced Optimal Transport

  • the article provides a visual explanation of what an optimal transport problem is
  • presents how the problem can be solved a lot simpler in 1D
  • extends on this insight to present how a multi-dimensional problem can be sliced and approximated in multiple 1D steps

WebGPU Render Bundle best practices

  • the article describes the concept of render-bundles and how they can be used to reduce CPU overhead
  • presents what changes are backed into the bundle and how updating referenced resources enables flexibility beyond static scenes
  • code examples and internals are discussed in WebGPU terms but apply to other APIs as well

A library for creating and manipulating spherical and zonal harmonics.

  • The author updated his library for spherical harmonics and zonal harmonics
  • added GLSL shader variation and shader toy
  • additionally, the update fixed several bugs and made improvements

Improved Multithreading in wgpu - Arcanization Lands on Trunk

  • the article presents a look into the internals of the gfx-rs wgpu implementation
  • demonstrates the limitations of the implementation in terms of multithreaded uses
  • shows what changes were made to reduce lock-contention and how the implementation might change in the future further

Performance tricks

  • short blog post lists a couple of tricks to use when writing shaders for higher performance
  • additionally provides a small trick on how to reuse data between iterations when using shaderToy

Unlocking GPU Intrinsics in HLSL

  • the blog post shows how to use Nvidia-specific intrinsics with D3D11 and D3D12
  • how to use them from shaders and how to verify that the hardware supports it
