Systematic modification of ship hull forms using B-splines
Systematic modification of ship hull forms using B-splines航空宇宙技術研究所 6-7 JUN. 1996 東京 日本 National Aerospace Laboratory 6-7 JUN. 1996 Tokyo Japan 縦横のメッシュ状のスプラインネットで定義された、例えば船体のような滑らかな物体形状は、メッシュの交点を移動させることによって高い自由度で変形させることができる。しかし、この高い自由度はかえって実施作業を困難にする。まず、設計者である人間がこの変形作業を実施する場合、変形によって元の曲面の滑らかさが損なわれないためには、各交点の移動量が全体として滑らかに分布していなければならないが、設計者がそのような移動量を直接各交点で与えることはほとんど不可能である。メッシュを粗くすると、滑らかな分布を与えることは容易になるが ...
