Abstract
AbstractThis paper describes the application of B‐spline interpolation to the problem of rational transformation in computerized 2‐D animation. The technique described herewith can also be applied to the resolution independence problem which arises when the same production workstation is used to produce animation series to be recorded on variable film sizes This article fully explains our solution to the problem of rational zoom. An algorithm has been written to speed up computations by spreading the computing load among similar technical workstations hooked up in a network. Large magnifications of professional quality can be achieved in very little time and very smooth animation effects can be obtained by applying rational zooms with magnification coefficients that are a time function.
