Notes

Made as a thank-you gift for my Ph.D. advisor.
My dissertation research made heavy use of 1D and 2D Sobol sequences to generate well-distributed point samples from various domains, such as selecting wavelengths from the visible spectrum.

I’ve included an image of the original point distribution, showing how the points are scattered in a seemingly random manner that’s actually better than random for graphics purposes, because it avoids clusters and gaps pretty well. I used the first 128 points of dimensions 2 & 3 of the Sobol sequence, using direction numbers from Joe & Kuo2003.

This might be the biggest project I’ve ever made. Mostly I do baby blankets and other small stuff. Certainly nothing else I’ve made has been this size AND this complex.

Main blanket (the “plotting area”) is 150 rows x 150 stitches of Tunisian Simple Stitch, outlined in surface slip stitch. Border is moss stitch.

The sequence points are marked with coconut-shell buttons tied on with yarn, secured with a drop of Gorilla Glue. The tag is on the back of the origin, i.e. the corner that corresponds to (0,0). One of the photos shows the temporary grid lines I basted across the blanket to save my sanity while placing 128 buttons in mathematically determined locations.
