( 3 ) uniformed contours stacked together and constructed real boundary element method ( bem ) calculation models for e / meg research respectively by minimum distance method and 3d - delaunary based triangulation growth method . finally developed visualization algorithm based on surface rendering for the purpose of integration of structure and function information 在構建剖分模型上,用基于最短對角線(在兩層輪廓中心偏離較大的情況下,對輪廓進行了對中變換)和基于3ddelaunay的方法構建了計算模型;基于表面繪制的思想,實現了頭和腦的可視化。
