Move unchanging geometry, grids, and text into a PGraphics offscreen buffer during setup, then composite it with a single image() call each frame. This guide covers buffer creation, renderer matching, resize handling, memory limits, and verification steps.
Reduce CPU overhead in Processing by caching static geometry in PGraphics offscreen buffers. Learn how to implement invalidation flags and choose the right renderer for stable frame rates.
When a Processing sketch stutters because static elements are redrawn every frame, PGraphics offers an off-screen buffer you can composite with a single image() call. Here is how the pattern works, a concrete example, and the memory and renderer trade-offs to check.
Learn how to create and use an OpenGL Framebuffer Object to render to a texture, with a concrete example, trade‑offs, and verification steps.
Learn how to reuse a PGraphics buffer to draw static backgrounds once and boost frame rates in Processing sketches.
Use Processing's PGraphics class to draw offscreen: create the buffer once, wrap drawing in beginDraw/endDraw, composite with image(), and export with pg.save().
Learn how to use Processing’s PGraphics for off‑screen rendering to reuse drawings, apply effects, and avoid costly redraws each frame.
Cache complex static drawings in a Processing PGraphics offscreen buffer to cut per-frame draw calls and raise frame rate, with code, memory costs, and verification steps.
Drawing directly to a window surface can be slow because of per-pixel format conversion. A similar off-screen surface matches the target format, so you draw once and blit once.
