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