Description

Smooth-Maximum, the most useful function is a free YouTube video on the Inigo Quilez channel.

Inigo Quilez video deriving smooth maximum functions from algebraic rewrites of max, then applying them to blend procedural surfaces and soft CSG-style rock sculpting. Walks from absolute-value and square-root forms through biased smooth variants and related smooth branchy functions. Useful for graphics programmers working with SDFs, procedural modeling, and differentiable-friendly blends.

It is aimed at intermediate graphics programmers and matches the audience implied by Inigo Quilez's other work.

Access is a single free YouTube video with on-screen code and narration; numbered episodes assume you followed earlier parts of the same series.

It is useful when you want practical detail beyond a title or store listing and prefer primary-source explanation from the author or maintainer.
