A single complete Framebuffer Object with matched formats and explicit sync keeps off-screen rendering on the GPU. Learn the minimal setup, trust boundaries, and failure checks.
Learn how to use Processing’s PGraphics buffer for clean off‑screen rendering, compositing, and image export. A step‑by‑step example shows gradient generation, memory tips, and trade‑offs.
When to use PixiJS RenderTexture, compare it to alternatives, and see a minimal example that creates, renders, and displays a RenderTexture in a scene.
Use PGraphics to draw static content once into an off-screen buffer and blit it each frame with image(), turning expensive per-frame redraws into a single cheap texture copy.
When building a headless rendering pipeline, the goal is to create an OpenGL core profile context through EGL that can render off-screen and share resources across windowed and headless platforms without relying on native window system surfaces. The integration boundary here is between OpenGL's core profile requirements—such as shader-based rendering and exp
