Abstract

The success of using streamline technique for visualizing a vector field usually depends largely on the choosing of adequate seed points. This paper propose a new technique for automatically placing seed points to create evenly spaced streamlines on 3D parametric surfaces found in curvilinear grids. The new technique extends Jobard and Lefer's distance-based single pass approach for placing streamlines in the 2D computational space of the surface. Experimental result show that the new technique produces streamline images of competitive quality at much lower computational expense image-guided progressive refinement approach. A method for compensating the visual streamline density distortion caused by projection is also presented.
