Erratum to “Rational Bézier Guarding”
Computer Graphics Forum · 2025
Khanteimouri P., Mandad M., Campen M.: Rational Bézier Guarding. Computer Graphics Forum 41, 5 (2022), 89–99. The proof of Lemma 5 contains a mistake; while various kinds of variation diminishing properties of Bézier triangles are known, one of the specific geometric kind assumed is not available. The lemma does not hold in full generality as stated, for arbitrary Bézier triangles. Whether it holds for the restricted class of Bézier triangles constructed by the method is an open question, no counterexample is known. We apologize for this error.
