Imperfect Environment Maps

• using ideas from imperfect shadow map point-cloud rendering to implement reflections
• generates a point cloud around the track
• screen space pixels that are close to points of the point cloud transfer their color onto the points
• the point cloud is then projected onto a sphere around the car and used as an environment map to add reflections on the cars

Musings on cross-platform graphics engine architectures – Part 2

• breaks down the engine into two separate related concepts, Resource and Command management
• discusses how to interact with resources
• introduces the idea of state scopes to prevent state leaking
• commands are recorded into engine specific command buffers that are later converted into the API specific format

High-Performance Graphics 2018

• slides for most of the talks have already been published

DX12 Ray Tracing Tutorials

• Nvidia tutorial on how to integrate DirectX raytracing and rasterization so that both rendering paths can be used within the same application
• how to initialize the API, create DXR acceleration structures
• how the ray tracing pipeline works, manage shaders, resources, and shader binding tables
• implementation of the required raytracing shaders to produce identical results with the rasterization pipeline

Rendering the Moana Island Scene Part 1: Implementing the Disney BSDF

. short description of the different aspects of the Disney BSDF, including source code

Screen-space Water Rendering

• a technique to render screen space water using unity
• water particles write information into offscreen buffers to accumulate water information
• these buffers are then resolved to form a continues water surface instead of individual blobs

A Multi-Faceted Exploration (Part 3)

• improves upon the multiple scattering approximation from the previous part of the series
• the result is a model that only requires a 2D LUT to be pre-calculated

Shader Graph Updates and Sample Project

• walkthrough of two vegetation shaders created with the visual shader editor that was added in Unity 2018.1

Uniform points in sphere and capped cone

• how to improve the generation of uniform points in a sphere, disk, and a spherically capped cone

Clipping Objects with a Plane

• a tutorial that shows how to clip a mesh in a pixel shader against a plane using unity

Confetti Shader Translator - Alpha

• a web tool that allows the conversion from HLSL Shaders to HLSL 6.2, GLSL 4.5 and Metal 2.1

The other pathtracer 5: Optimizing Triangle-Ray Intersections

• choosing a different algorithm to optimize triangle-ray intersection tests and vectorizing the calculations

Tiled Blue Noise

• a quick overview of blue noise tiled with various tile sizes from 16x16 to 256x256

A Cross-platform Evaluation of Graphics Shader Compiler Optimization

• explores source to source optimizations techniques using the LunarGlass framework with GLSL shaders
• comparison of different optimization techniques and the effects on runtime performance
• results vary significantly between different shaders and target platforms

The State of GPGPU in Rust

• overview of libraries available to write GPGPU applications using the Rust programming language

Lighting the Unlit

• description of the “unlit” light system being used
• it allows lights to modify tint, brightness and contrast to enable the 2D characters to match the environment better

Metal shaders: blending basics

• a short explanation and Metal shader code for different blend modes as described in the PDF specification

Shader Showcase Saturday #4

• overview of different fire effects that are based around animated noise textures

Shader Showcase Saturday #5

• overview of different rain effects with links to more in-depth articles discussing the showcased effects

Microsoft/glTF-SDK

• Microsoft open sourced their library to read and write GLTF model files
