【摘要】 为了动态地显示大坝地震反应数据场的整体变化情况,本文提出了基于网络、表面、体绘制和多断面的数据场三维动态可视方法,可以立体地反映出三维数据场的整体数据分布,实现大规模数据场实时动态可视,使人们及时准确地了解大坝地震反应过程,正确地做出决策。可视化图形用VC6 0编程,并使用了OpenGL函数,在实现动态显示时,采用了连续帧显示技术。更多还原

【Abstract】 Several 3D dynamic visualization methods based on net,surface,volume rendering and multiple sections are applied to display the seismic response data of dam.The distribution of data field for whole dam can be displayed clearly.The visualized figures are programmed using VC 6.0 and OpenGL function is applied.The continuous frame display technology is adopted to realize dynamic display.更多还原
