Final answer:
The Painter's Algorithm handles animation by continuously sorting and redrawing 3D polygons from back to front for each frame. However, its inefficiency with transparency and intersections, coupled with increased computational load, makes it less suitable for complex animations.
Step-by-step explanation:
How Painter's Algorithm Handles Animation
The Painter's Algorithm is a technique used in computer graphics to render three-dimensional objects onto a two-dimensional screen.
It works by sorting and painting each polygon of the 3D model from back to front in what is termed 'painter's order.' This method ensures that the polygons further away are drawn first, followed by the closer ones, which may overlap and, therefore, cover the farther ones.
When applying the Painter's Algorithm to animation, it's important to continuously sort and redraw the frames for each movement of the objects or viewpoint to maintain the correct depth order.
This implies an increased computational workload, especially with more complex scenes or faster actions.
Inefficient handling of transparency and objects intersecting is a well-known drawback of the Painter's Algorithm in animated sequences. Advanced alternatives like depth-buffering (Z-buffering) have largely replaced the Painter's Algorithm in modern graphics processing due to their better handling of dynamic scenes, including animations.
