摘　　要：基于OpenGL技术对湖底清淤过程进行可视化,利用实测的采样点拟和Bezier曲面展现水下淤泥的三维形态,提出根据工程不同进展阶段返回的采样点淤泥厚度,利用最小二乘法建立淤泥厚度h与水泵抽取量Q的关系曲线,并运用了三维模型读取、光照、粒子技术等OpenGL技术。该成果不仅局限于本次工程,而且还能对未来该湖的清淤工作提供技术依据。The research based on OpenGL makes the process of lake dredging up visible. Through Bezier surface fitting, it represents surface of underwater silt by sampling points .According to sampling points, it constructs the curve about thickness of silt h—volume Q by least square method. It adopts of OpenGL technology of 3D model reading, illumination, particle system etc. Thereby it makes the research not only restricting scope by itself, but also consulting future project.
