Outline of Final Research Achievements |
In the first year of this supported period, I proposed a guiding method of smoke flows which controls a high-resolution simulation according to a user-desired flow. This method is sufficiently faster than previous similar methods, and non-physical inputs can be used to the method. This method was presented at the top conference and published in the top journal on computer graphics. Then, in the final year, I extended the smoke guiding method and applied to a liquid simulation. I presented this at a domestic conference.

Academic Significance and Societal Importance of the Research Achievements |
煙のガイド手法では,従来手法において流体シミュレーションよりも大幅に計算時間がかかっていたが,従来よりも解く問題のサイズを大きく削減し,シミュレーションと同等のコストで計算ができる枠組みを提案した.また,常に物理法則のうちの1つを満たすこともでき,CGにおける流体の映像生成において,技術的に世界へ貢献した.また,そのガイド手法を拡張した液体への適用は良好な結果が得られており,本研究の目的としている世界で初の液体の流れの高精細化の実現が期待できるものである.
