✦ Synopsis

Morphing is one of the most well-used techniques for producing intermediate images which fill the gap between two stages of a displayed data set. Several 3D morphing methods have been developed for interpolating between synthetic data sets, but none have yet been devised for interpolating between scientific data sets. One of the morphing techniques used for such data sets in 2D is the segment warping algorithm. In this paper, we show that this technique can be extended to 3D data sets. The 3D morphing technique, which is composed of three modules (tweening, warping and dissolving) is first described and then applied to digital volumes (chromosomes at different stages of the cell mitosis) recorded by confocal microscopy. From the intermediate digital volumes created by this technique, movies are produced, which can help in the understanding of the dynamical behaviour of the 3D structure.
