| Summary: | This paper presents an improved seed point placement to locate initial seed points based on magnitude value. The vector field is separated in to grid to ensure the uniformity in generating streamlines and broader streamlines coverage, thus reducing poor visualisation information especially near to visualisation boundary. An evaluation using mean square error is conducted to evaluate the improvement in term of streamlines placement uniformity. Result shows that proposed method able to come out with lower mean square error value compared to evenly-spaced in across different separation distance, resulting better streamlines control to produce uniform visualisation result. Finally, the proposed method can be improved in many aspects to come out with a better visualisation result in two and possibly three dimension flow visualisation. |
