Shape Preserving Linear Interpolation (SPLINT)

摘要

The non-monotonicity inherent in linear interpolative systems can produce side-effects such as expansion or contraction of a shape during shape blending operations. A new shape preserving linear interpolation (SPLINT) system is introduced. SPLINT is an improvement over traditional linear interpolation techniques, allowing transformations to be performed without the expansion and contraction of the intermediate images that is typical in standard techniques. As well as maintaining the shapes of objects during transformations, the examples used to test SPLINT illustrate how movement can be simulated by shape blending.
