- Z-buffering: Z-buffering is a widely used hidden surface removal technique that maintains a depth buffer for each pixel in the image. As each surface is rendered, its depth is compared to the depth value stored in the depth buffer. If the new surface is closer to the viewpoint, its depth value is stored in the depth buffer and the pixel is updated with the new surface's color.
- Painter's algorithm: The painter's algorithm is a simple hidden surface removal technique that renders surfaces in back-to-front order. This ensures that surfaces that are closer to the viewpoint are rendered over surfaces that are further away, eliminating the need for a depth buffer.
- BSP trees: Binary space partitioning (BSP) trees are a data structure that can be used to efficiently perform hidden surface removal. A BSP tree divides the scene into a hierarchy of convex regions, and each region is assigned a set of surfaces that are visible from within that region.
- Ray tracing: Ray tracing is a hidden surface removal technique that simulates the way light travels through a scene. By tracing rays from the viewpoint into the scene, ray tracing can accurately determine which surfaces are visible and which are hidden.
