Seed point placement techniques have been introduced and improved flow visualization research domains since the beginning of the introduction of streamlines visualization. It is a starting point of the streamlines. Thus, it is crucial because the result is directly impacted by the seed point placement. Improved seed point placement has been presented with the objectives to generate uniform streamlines placement, to have longer streamlines, and to highlight important regions in the visualization result. These three objectives need to be balanced because there is a trade-off between them. Most of the available seed point placement techniques only focus on one objective and sacrifices the other two. In this paper, the Magnitude-Based Seed Point placement technique is improved to be used in 3D space. Experts review is conducted to evaluate the result as there is no proper quantitative evaluation method for 3D visualization results. Feedback from experts shows that the proposed technique provides a better result with the same streamlines count.
