✦ Synopsis
This paper presents a new algorithm of volume rendering based on a dual representation of data. The algorithm improves both the image generation speed and its quality. Two shape descriptors are used to characterize the object: a Euclidean distance transform (EDT) and a digital Euclidean skeleton. The EDT is used at one point in time to accelerate the image generation and compute the skeleton of the shape, whilst the skeleton is used as an initialization of the processing of the implicit surface. The goal is to build an interactive system of visualization for the analysis of volumetric data, either in the setting of a qualitative exploration or as a guide for qualitative measurements. The speed of treatment together with good visualization should give the feasibility to achieve a 3D survey of a natural object in an interactive manner. The method has been successfully applied to both synthetic and real data.
