  title={Some Covariants Related to Steiner Surfaces},
  author={EMMANUEL BRIAND AND CLAUDE BRUCHOU and Alexandre A Steiner},
ABSTRACT. A Steiner surface is the generic case of a quadratically par ameterizable quartic surface used in geometric modeling. This paper studies q uadratic parameterizations of surfaces under the angle of Classical Invariant Theory. Pre cisely, it exhibits a collection of covariants associated to projective quadratic paramete riza ions of surfaces, under… CONTINUE READING
