Virtual reality based on graphic is constructed by means of computer graphic technique 基于图形学的虚拟现实是通过计算机图形学的方法构造的。
Besides, based on the computer graphic techniques, the author also studied the nature of subject projection, texture and lightning to generate three-dimensional vision of surveyed seafloor 同时利用计算机图形学的相关知识,对三维地形图进行材质、光照设置,逼真地反演出水下地形。
They worked closely with the chapel hill team, which was responsible for taking the “ animated sculpture ” data and using computer graphics techniques to turn it into a realistic scene for each user 教堂山团队和他们密切合作,负责取得活动塑像的数据,然后以电脑绘图技术让每个使用者都看到逼真的场景。
Via computer graphics techniques, it transforms data produced by scientific computing into geometric graphics or images so that they can be displayed on screens and be manipulated interactively . now visc has become a strong tool for the discovery and understanding of many scientific phenomena 它将科学计算过程中及计算结果的数据转换为几何图形及图像信息在屏幕上显示出来并进行交互处理,成为发现和理解科学计算过程中各种现象的有力工具。
Numerical simulation mainly is performed by finite element method and discrete element method in physics; based on computer graphic techniques and image processing techniques, visualization and graphic simulation are a shortcut method to steer the calculation process and to comprehend the computation results 数值仿真主要采用有限元、离散元等数学物理模型,而可视化技术及图形仿真基于图形学和图像处理技术,是驾驭计算过程及理解大体积数据的唯一有效途径。
