Abstract

Abstract

With the fast growing size and dimensionality of scientific datasets, inspection and rendering data features has become an important topic when traversing through it. We propose opacity transfer function with trapezoid shape having an overlapping region to extract different layers when using Compute unified device architecture (CUDA)-based volume ray-casting. We define different tools such as probe for 3D inspection and virtual lenses for 2D inspection of inner layers in Region-ofinterest (ROI). We verify the effectiveness which allowing inspection of structures both interior layers in ROI and exterior semi-transparent ones at interactive frame rates.
