Quantizing tangent frames is a technical blog article by Arseny Kapoulkine.
Blog post by Arseny Kapoulkine comparing compact encodings for orthonormal tangent frames, including octahedron, quaternion, tangent-angle, and diamond schemes with measured angular error. Aggregates prior work and discusses bit allocations for roughly four-byte TBN storage versus eight-byte baselines. Aimed at engine and mesh-pipeline programmers packing normals and tangents. I’ve been working on tangent space generation recently, and also.
It is aimed at advanced graphics programmers and matches the audience implied by Arseny Kapoulkine's other work.
The article is a free HTML blog post meant to be read in one sitting, with diagrams or code snippets embedded in the page.
It is useful when you want practical detail beyond a title or store listing and prefer primary-source explanation from the author or maintainer.

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.

One tileable texture is sampled twice in a Surface shader at different scales and scroll speeds, combined with min(), then tinted onto albedo with slight RGB UV offsets for dispersion. The walkthrough covers _ST tiling, _Time animation, HDR albedo above 1.0, and Post Processing Stack v2 bloom.
