Abstract

Streamarrows are a technique to enhance the use of streamsurfaces by separating arrow-shaped portions from the remaining streamsurface. We present a hierarchical streamarrows algorithm as an extension to this technique: Streamarrows are locally chosen from a stack of scaled streamarrows textures to avoid too big or small streamarrows in the rendered image. We furthermore present techniques how streamarrows can be extended into 3D, namely perpendicular to the streamsurface: streamarrows can be shifted slightly out of the streamsurface. Another extension in this category is to represent the outline of streamarrows as 3D tubes. We show a set of images which have been rendered using this technique and report about ongoing research.
