Implementing hybrid rendering

In this recipe, we will explore the integration of rasterization, specifically deferred rendering, with ray-traced shadows.

In Chapter 4, Exploring Techniques for Lighting, Shading, and Shadows, we implemented deferred rendering, incorporating techniques such as shadow mapping, screen space AO, and screen space reflections. These techniques allowed us to generate multiple textures, which were then composited during the lighting pass. Within this recipe, you will gain insights into generating shadow textures using ray tracing, which will help in overcoming challenges associated with techniques such as screen space shadow mapping. Screen space shadow mapping relies on the information available in the rendered image. It doesn’t have complete access to the entire 3D scene geometry. This limitation can result in inaccuracies and artifacts. Screen space shadow mapping is susceptible to aliasing issues, particularly along edges and boundaries due to...
