Weights and Cross Ratios on Generalized Rational Curves and Surfaces of Arbitrary Function Class

摘要：

For the generalized rational curves and surfaces with arbitrary basic functions, which can be non- algebraic, if one or two or three weights are changed but others remain unchanged, the ratio of each changed weight and its original weight is separately equal to the cross ratio of four points or areas or volumes.
