A decision guide for picking a Processing renderer — JAVA2D, P2D, P3D, or FX2D — with a comparison table, correct settings() usage, and a frameRate-based validation sketch.
A step‑by‑step guide to diagnose why a Processing sketch opens a window but shows only a blank background, with checks, fixes, and when to seek further help.
Learn how to use PGraphics for offscreen rendering in Processing. Discover how to match renderers for GPU acceleration, manage VRAM, and implement post-processing effects like blur.
Learn how to optimize real-time visual synthesis in Processing using the P2D renderer, focusing on reducing PCIe bottlenecks and OpenGL state changes.
Stop using manual X/Y coordinate math. Learn how to use the PVector class in Processing to implement velocity, acceleration, and smooth steering behaviors for natural motion.
Learn how to eliminate frame rate stutters in Processing by replacing object-oriented particle systems with the Parallel Array (Parray) pattern for better memory locality.
Deep offset pagination with Hibernate slows linearly as OFFSET grows. Use keyset pagination with a WHERE clause on the last seen sort key and a suitable index for stable page times.
Learn how to create an offscreen graphics buffer with PGraphics, draw static content once, and reuse it each frame to reduce CPU load in Processing sketches.
Learn how to cache static drawing in a PGraphics buffer to cut per‑frame work and keep animations smooth, plus the memory trade‑off to watch.
