THE STORY OF THE 3DFX VOODOO1

• provides a look at the 3DFX VOODOO1 GPU from the mid-90s
• shows how the hardware and rendering pipeline was designed
• comprising between the visual result of the software renderer and the GPU acceleration

Unity - Grass Shader

• a tutorial that explains how to render grass using Unity
• uses a mix of geometry and tesselation shaders
• covers how to generate geometry from the geometry shader, explains tangent space, and adds vertex attributes
• tesselation shader is used to control the density of the grass
• wind is applied to make the grass move
• lighting and shadows are added

2d Raymarched Smoke

• walkthrough of a simple cloud shading setup using the Unity shader graph system

Bringing GPU acceleration to Windows containers

• with Windows Server 2019 or Windows 10, version 1809 GPU acceleration for Direct3D based workloads is now supported in Docker
• also enabled Windows ML hardware acceleration

Alternative Take on the Split Sum Approximation for Cubemap Pre-filtering

• describes how cubemap pre-filtering for image-based lighting is done in Unity’s HD Render Pipeline
• derivation of the filtering equation and comparison against the split sum approximation used in UE4

New in D3D12 – GPU-Based Validation (GBV) is now available for Shader Model 6.x

• windows update 19H1 supports GPI based validation with shader model 6, generated by the DXC compiler

Creation Graphs

• presents the Creation Graph
• a graph-based system that allows the definition of functionality, which mixes GPU and CPU based work in a single graph
• examples presented: cubemap filtering for image-based lighting and skybox rendering

Technically Art: Issue 12 (05.04.2019)

• collection of tweets related to a variety of tech art articles
• many great looking effects

GDC 2019 - Vault

• videos and slides for GDC 2019 have been released on the vault

Anti-Ghosting with Temporal Anti-Aliasing

• presents techniques used to alleviate ghosting in the TAA solution of “The Grand Tour Game”
• uses the stencil to mark object groups and does not blend between with history buffer pixels when the stencils differ
• uses per-pixel depth and velocity to disable TAA so as to further reduce ghosting on shadows

Keeping the Blue Side Up: Coordinate Conventions for OpenGL, Metal and Vulkan

• presents the coordinate conventions for Metal, OpenGL and Vulkan
• how they differ and how to deal with the difference in a mixed API scenario

• series part 1 of the reverse engineering of The Witcher senses
• explains how objects are selected using the stencil buffer

Reverse engineering the rendering of The Witcher 3, part 13b - witcher senses (outline map)

• reverse engineering of The Witcher sense effect
