The rendering pipeline for static images and animated scenes differs primarily in time dependency: static images focus on a single frame, while animated scenes require time-based frame sequencing and motion calculations.
Static image pipelines process one frame with fixed geometry, textures, and lighting—no time variables are involved. Core steps include geometry processing, lighting, and shading to produce a single, final image.
Animated pipelines, by contrast, iterate over time, updating object positions, rotations, or deformations frame-by-frame. They also integrate motion-related effects like motion blur to simulate smooth movement across sequential frames.
In short, static rendering handles a single moment, while animated rendering manages a sequence of dynamic moments over time.
