Abstract: | We present a method to rapidly build an irradiance cache based on a local illumination environment approach. This cache is obtained by a stream simplification of a photon map. The photons are K-Means clustered per voxel into sets of virtual directional light. These lights are stored into an irradiance texture to provide a real-time rendering of a global illuminated scene. This method can be integrated into an existing GPU shader to obtain complex material rendering and can be accelerated by texture atlases. |
