Strong -Bases for Rational Tensor Product Surfaces and Extraneous Factors Associated to Bad Base Points and Anomalies at Infinity

LY Shen, R Goldman - SIAM Journal on Applied Algebra and Geometry, 2017 - SIAM
We investigate conditions under which the resultant of a μ-basis for a rational tensor product
surface is the implicit equation of the surface without any extraneous factors. In this case, we …

Role of moving planes and moving spheres following Dupin cyclides

X Jia - Computer Aided Geometric Design, 2014 - Elsevier
We provide explicit representations of three moving planes that form a μ-basis for a standard
Dupin cyclide. We also show how to compute μ-bases for Dupin cyclides in general position …
