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
