Focal region-guided feature-based volume rendering

摘要: In this paper we advocate the use of a focal region-guided feature-based volume renderer that offers an alternative for visualization internal structures volumetric data. We describe promising technique communicating first impression object shape or contour while at same time providing detailed information data with lens-like region. designed method generating contours and enhancing features to depict context out region based on gradient volume. region, render interesting using direct rendering method. The is guided by through which can specify what subset render. connection between structure interior exterior gives better understanding spatial relationship. This communicate existence, form, location underlying targets minimally occluding them.
