![]() ![]() This technique enables applications to quickly approximate complex global lighting effects in dynamic environments (such as radiosity from dynamic lights and dynamic objects). ![]() This chapter describes a fully GPU-accelerated method for generating one particularly graphically interesting type of environment map, irradiance environment maps, using DirectX Pixel Shader 3.0 and floating-point texturing. Real-Time Computation of Dynamic Irradiance Environment MapsĮnvironment maps are a popular image-based rendering technique, used to represent spatially invariant spherical functions.
