Explain the concepts of view frustum and view frustum culling in 3D computer graphics. How do they contribute to scene optimization?
View frustum is a geometric shape representing the visible 3D space in a camera’s perspective. It consists of six planes: near, far, left, right, top, and bottom. View frustum culling is an optimization technique that eliminates objects outside the view frustum from rendering calculations.
Culling reduces computational load by discarding invisible objects before they reach the rendering pipeline. This improves performance and frame rates, especially in complex scenes with numerous objects. By focusing resources on visible elements, view frustum culling contributes to efficient scene optimization.
