Basic Color Science for Graphics Engineers

• presents how the RGB color representation is based on human vision
• shows how to visualize the visual color range in chromaticity diagrams
• presents the Rec. 709, sRGB, Rec. 2020 and XYZ color space
• shows which color ranges can and cannot be represented in each space

Crytek Presentations

• Crytek removed all presentations from their website
• a user has uploaded a backup copy of many presentations to his dropbox

Unity GPU culling experiments Part2 – optimizations

• presents how to optimize the compaction pass in a GPU culling pipeline
• reduce memory bandwidth usage by taking advantage of shared memory and compression of data that needs to be processed
• wrap level and shuffle instructions allow further optimizations

Fast, Constant Time Sphere Indexing, Part 2

• shows how to simplify the math for constant time sphere indexing (the technique was described in issue 64

Direct3D 11 on 12 Updates

• overview of improvements to the system that allows D3D11 applications to be run using D3D12
• improved threading behavior
• new APIs will allow the underlying D3D12 resources to be requested from the D3D11 objects

Thoughts on graphics APIs and libraries

• discusses author’s view on the state of low-level graphics APIs (Vulkan, D3D12, Metal)
• presents how the abstraction level might not be the right one
• too low-level for ease of use but too high-level to guarantee predictable performance on all platforms

“Ray Tracing Gems” preprints available part by part this month

• every few days a new preprint article from the “Ray Tracing Gems” book will be released
• requires a free Nvidia developer account

• shows to create vertex and constant buffers
• explanation of memory management and binding model

My take on shaders: UI SDF Icon shader

• shows how to sample a signed distance field in a Unity UI shader
• signed distance field UI shaders allow the UI to be resolution independent
