perhaps this resource too http://web.iitd.ac.in/~hegde/cad/lecture/L14_curves_bspline.pdf

right, the circular constraint is no good without this because the non-clamped basis can easily get around this.

here we have a circular constraint on the first and last basis fns. but the value at 0. and 1. is also determined by the two basis fns adjacent to these :)
