Abstract

Screen-space Ambient occlusion (AO) is a popular global illumination technique which can be used to achieve a better understanding of complex 3D streamtubes scenes. This paper proposed an anisotropic screen-space AO method to visualize complex 3D streamtubes. The basic idea is to utilize the characteristics of 3D streamtubes to design two anisotropic filters to guide screen-space sampling as well as spatial reusing. More specifically, this paper proposed to anisotropically generate samples perpendicular to the direction of streamtube to calculate AO. This mechanism can reduce the number of samples required to generate satisfactory results. In order to further improve the performance of the algorithm, this paper proposed to anisotropically reuse AO results from nearby pixels along the streamtube direction. The experimental results indicate that proposed algorithm outperforms the existing solutions both in rendering quality and performance.
