A practical guide to picking JAVA2D, P2D, or P3D in Processing 4.x, featuring a performance benchmark, feature comparison, and a selection checklist.
Stop tracking X and Y manually. Learn how to use PVector in Processing to create smooth, physics-based steering behaviors using normalization and magnitude limiting.
Use PGraphics offscreen buffers to draw static content once and reuse it each frame, cutting per-frame drawing cost in Processing sketches.
Learn how to implement and optimize the p5.js setup and draw loop for smooth, interactive animations, including window resizing and performance tuning.
Since Processing 3.0, surface configuration must happen in settings() before the window exists. This guide shows how to migrate legacy sketches, choose renderers, and handle HiDPI pixel density.
Learn how to properly implement the p5.js createCanvas and draw loop architecture to create smooth, real-time animations while avoiding common rendering pitfalls.
A practical decision guide for p5.js architecture: when to use global vs instance mode, P2D vs WEBGL renderer, and how to validate your choice with concrete benchmarks and migration checks.
Global mode is fine for demos, but on real pages it pollutes the namespace and leaks animation loops. Here's why p5.js instance mode — with a worked example and cleanup pattern — is the practical default.
Immediate-mode drawing re-sends every shape each frame, which is why dense Processing sketches crawl. Baking static geometry into a PShape group uploads it once and redraws it in a single call.
