Implementing Dual Depth-Peeling

One of the main drawbacks of the Depth Peeling algorithm is that it requires multiple passes, each of which may consist of rasterizing the entire scene. The Dual Depth-Peeling algorithm extends the original Depth Peeling algorithm by peeling two layers at the same time, almost effectively cutting the number of passes by half. In this recipe, we will focus on implementing the Dual Depth-Peeling algorithm. We will address one of the key limitations of the Depth Peeling algorithm, namely its requirement for multiple passes which may involve rasterizing the entire scene. You’ll learn how the Dual Depth-Peeling algorithm improves upon the original by peeling two layers concurrently, thus potentially reducing the number of passes by nearly half. This insight will empower you to handle complex scenes with greater efficiency and speed.
