Precomputed Radiance Transfer Field for Rendering Interreflections in Dynamic Scenes
In this paper, we introduce a new representation – radiance transfer fields (RTF) – for rendering interreflections in dynamic scenes under low frequency illumination. The RTF describes the radiance transferred by an individual object to its surrounding space as a function of the incident radiance. An important property of RTF is its independence of the scene configuration, enabling interreflect...
متن کاملRendering Microgeometry with Volumetric Precomputed Radiance Transfer
Although computer graphics hardware has made tremendous advances over the last few years, there are many things which are still not feasible to render in realtime. One of these is the subset of surfaces referred to as ’microgeometry,’ where many small individual pieces combine to create a complex surface. Microgeometry is a problem for typical polygonal rendering systems, the method used in the...
متن کاملPrecomputed Radiance Transfer
This paper describes a method for rendering interreflections, self-induced shadows and caustics in real-time in a general low-frequency lighting environment. The method handles environment and area lighting and glossy as well as diffuse objects. The lighting environment is projected onto a lowfrequency spherical harmonic basis. Before the rendering a transfer vector (diffuse case) or a transfer...
متن کاملAdapting Precomputed Radiance Transfer to Real-time Spectral Rendering
Spectral rendering takes the full visible spectrum into account when calculating light-surface interaction and can overcome the well-known deficiencies of rendering with tristimulus color models. We present a variant of the precomputed radiance transfer algorithm that is tailored towards real-time spectral rendering on modern graphics hardware. Our method renders diffuse, self-shadowing objects...
متن کاملWavelet Basis Functions for Precomputed Radiance Transfer
Precomputed Radiance Transfer (PRT) aims at computing global illumination effects such as soft shadows and object interreflection in realtime. This is accomplished by precomputing the factors of the Rendering Equation and projecting them into a suitable basis which allows to combine them efficiently at runtime. Several basis function have been proposed for PRT. Recently, Haar wavelets have been...
