Physically Based Rendering, online

• the complete 3rd edition of Physically Based Rendering is now online for free
• the post explains the history of the book and decisions that led to making the book available for free
• authors can be supported on https://www.patreon.com/pbrbook

From screen space to voxel space

• summarizes voxel ray tracing implementation, memory and performance optimizations
• show the different artifacts that can be encountered and their solutions

Adding multiple bounces

• next part in the Metal ray tracer series that adds support for multiple bounces to simulate global illumination
• implements importance sampling for diffuse BSDF

Improving material system

• extending the material system of the Metal raytracer so that multiple materials can be expressed and importance sampled correctly
• changes sampling heuristic to support multiple importance sampling. This enables both rough and mirror-like surfaces

Multilayer Light Simulations: More Beautiful Images, Faster

• 2-minute video summary of the “Position-Free Monte Carlo Simulation for Arbitrary Layered BSDFs” paper

Flavors of Sampling in Ray Tracing

• overview of the strengths and weaknesses of different sampling techniques in ray tracing
• presents links to papers that present methods that are aimed at creating better-stratified sampling results

niagara: Future of rasterization

• stream that adds support for rendering meshes using Nvidia mesh shader extensions

niagara: Optimizing mesh rendering

• during the stream, the mesh shader pipeline is optimized
• performance parity with the classical rasterization pipeline is achieved without GPU culling

How to make a fake interior effect with unity using reflection probes

• shows how to implement interior mapping using the Unity reflection probe system
• explains how to set up the model and environment to generate the required probes and how to apply the reflections to the windows

Rust Mesh Optimizer

• rust version of the meshoptimizer library is now available
• the post explains how to setup Rust code to be able to compile, link and use existing C code from Rust

Global Illumination in Godot Engine @ Gamelab BCN 2018

• the presentation explains how Global illumination has been implemented in the Godot engine
• talking about GI probe generation, deterministic light baking and the interacting with the shading pipeline

How I Grow with Grass Shader

• walkthrough of a Godot shader that uses particles to spawn vegetation meshes based on height map and feature (biomes) map data

Alpha blending using pre-multiplied alpha

• a brief summary of the usage of premultiplied alpha using Vulkan
• pre-multiplication is done in the pixel shader, no texture pre-processing is used
