Vulkan memory barriers and image layouts explained

Visit resource ↗Description
Vulkan memory barriers and image layouts explained is a long RasterGrid technical article by Daniel Rakos clarifying pipeline barriers, memory visibility, and image layout transitions in Vulkan.
It separates execution dependencies from cache flush and invalidate behavior, walks RAW/WAR/WAW hazards, buffer versus image barriers, split event-based barriers, Synchronization2 stage/access coupling, and why layout transitions exist on architectures such as historical GCN. Misuse is framed as a source of corruption or large, hardware-dependent performance cliffs.
It is for intermediate to advanced Vulkan developers who already issue barriers but want hardware-motivated guidance rather than full pipeline drains.
The article is free on the RasterGrid site as deep explanatory prose with diagrams.
It is useful as a single reference when debugging sync bugs or trimming over-synchronized frames.

Alan Zucconi's A gentle introduction to shaders in Unity3D (June 2015) is part one of his Gentle Introduction series on alanzucconi.com, aimed at Unity developers new to GPU programs. It connects vertices, materials, and shaders in Unity's pipeline, covering ShaderLab Properties and SubShader layout, inspector uniforms, Queue tags, ZTest, and the surface-versus-vertex/fragment split for lighting versus effects. Little prior shader knowledge is assumed; fixed-function shaders are skipped as obsolete.
