ACM, New York, NY, USA, , Article 99 , 1 pages | Abstract: | It is common to use factored representation of visibility, lighting and BRDF in inverse rendering. Current techniques use Haar wavelets to calculate these triple product integrals efficiently [Ng et al. 2004]. Haar wavelets are an ideal basis for the piecewise constant visibility function, but suboptimal for the smoother lighting and material functions. How can we leverage compact high-order wavelet bases to improve efficiency, memory consumption and accuracy of an inverse rendering algorithm? If triple product integrals can be efficiently calculated for higher-order wavelets, the reduction in coefficients will reduce the number of calculations, therefore improving performance and memory usage. Some BRDFs can be stored five times more compactly. | Notes: | Poster publication | Document URI: | http://hdl.handle.net/1942/16014 | ISBN: | 978-1-4503-2342-0 | DOI: | 10.1145/2503385.2503494 | Category: | C2 | Type: | Proceedings Paper |
