【 摘 要 】

The problem of degree reduction and degree raising of triangular Bezier surfaces is considered. The L-2 and I-2 measures of distance combined with the least-squares method are used to get a formula for the Bezier points. The methods use the matrix representations of the degree reduction and degree raising. (C) 2003 Elsevier B.V. All rights reserved.
