Summary: We correct some errors in ``Intersection Algorithms for Lines and Circles'', by \textit{A. E. Middleditch}, \textit{T. W. Stacey} and \textit{S. B. Tor} [ACM Trans. Graphics 8, No. 1, 25-40 (1989; Zbl 0686.65008)], as well as point out an additional reference which treats the same topic more elegantly in terms of \(2 \times 2\) Hermitian matrices.

| selected citations These citations are derived from selected sources. This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | 1 | |
| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
| influence This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | Average | |
| impulse This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network. | Average |
