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 Box Arrangement


Variance in Integration over analytic arrangements of random boxes.

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


Average Fourier spectrum of 10 pointsets of 4096 points each

Average Radial spectrum of 10 pointsets of 4096 points each
