This has led to a large number of algorithms for reducing the depth buffer bandwidth. Unfortunately, these have mostly remained documented only in the form of patents. Therefore, we present a survey on the design space of efficient depth buffer implementations. In addition, we describe our novel depth buffer compression algorithm, which gives very high compression ratios.Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Picture/Image Generation]: framebuffer operations
