Results from our LDBN sampler with m=64 and t=64 Clicking on a picture will open it in full size.
Distribution
Distribution of 1024 points
Discrepancy
Discrepancy as a function of the number of points
Integration Disk
Variance in Integration over an analytical disk, measured by integrating with several realisations of the point set and computing the variance of those realisations
Integration HDR
Variance in Integration over an HDR image with an isotropic spectrum, measured by integrating with several realisations of the point set and computing the variance of those realisations
Variance in Integration over an HDR image with an anisotropic spectrum, measured by integrating with several realisations of the point set and computing the variance of those realisations
Spectral
Fourier spectrum of a pointset of 16k points each
Radial spectrum of a pointset of 16k points each
Anisotropy spectrum a pointset of 16k points each
Aliasing
Zoneplate test sin(x*x + y*y), using 1 sample per pixel and a Mitchell Filter for reconstruction on the domain [0,1).
Zoneplate test sin(x*x + y*y), using 4 sample per pixel and a Mitchell Filter for reconstruction on the domain [0,1).
