Streamline construction algorithm for 3D flow fields
Xundong Liang, Bin Li, Shenquan Liu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
Streamline construction is an important means for visualizing 3D flow field. Many existing methods are based on regular grid field. Constructing streamlines in structured grid field is more complicated. The main difficulties are the location of an arbitrary point and the interpolation in irregular cells. This paper presents a method for streamline construction in structured 3D flow field. We use structured-point to represent the position of a point and the relationship with its surrounding faces. The point location is made directly in physical space. This method does not need extra memory expense and preprocessing. The implementation and results are also discussed.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
