An Introduction to Canvas in GNU Emacs

A new canvas feature has been merged into upstream GNU Emacs, landing in the Emacs 32 release cycle. It exposes an ARGB32 pixel buffer as a new image type, accessible both from Emacs Lisp and via the dynamic module API, letting developers update pixels directly and redraw with canvas-refresh without triggering a full redisplay. The author, who built the Emacs Reader project, walks through the FAQ, the underlying image/text-property API, and three demos: a bouncing ball, a chaotic double pendulum, and a 3D rotating points-in-space renderer built via a C dynamic module ported from tsoding's olive.c.
