“…However, they do not accelerate the computation of the final high quality solution, which is the objective of our work. Object space interpolation has also been used for the purpose of fast previewing [16], [17]. Sparse sampling and interpolation for high quality rendering was used in [7], [1].…”

Abstract-In this paper, we present a ray tracing-based method for accelerated global illumination computation in scenes with lowfrequency glossy BRDFs. The method is based on sparse sampling, caching, and interpolating radiance on glossy surfaces. In particular, we extend the irradiance caching scheme proposed by Ward et al.[1] to cache and interpolate directional incoming radiance instead of irradiance. The incoming radiance at a point is represented by a vector of coefficients with respect to a hemispherical or spherical basis. The surfaces suitable for interpolation are selected automatically according to the roughness of their BRDF. We also propose a novel method for computing translational radiance gradient at a point.

“…If we allow tracked points to persist even when they co-occupy a pixel, then more sophisticated reconstruction methods could be applied to increase point reuse, in the spirit of Simmons et al [5] and Popescu et al [4]. We have not pursued this in the present work, noting that the former technique uses sparser sample sets than we do, and the latter requires special purpose hardware.…”

Ray tracing exhibits visible temporal aliasing artifacts in interactive viewing of complex datasets. We present a technique to reduce scintillation in point sampled imagery by targeting new rays to intersection points from previous frames. Remaining artifacts are abated by blending between successive frames. The algorithm achieves a reduction in scintillation comparable to that of supersampling, but at a significantly lower cost. Sample animations are available online.

“…Rigau et al Rigau et al (2002;2003a;b) introduced the Shannon entropy and also the f-divergences as the measure to conduct adaptive sampling. Mitchell Mitchell (1987), and later Simmons and Sequin Simmons & Sequin (2000), utilized the contrast to do adaptive sampling. Tamstorf and Jensen Tamstorf & Jensen (1997) Purgathofer's approach to propose the tone operated confidence interval.…”
