abstract : in this article, we described the system design object, the plan of function module, scene organization and fast rendering algorithm in detail 文摘:本文对系统的总体设计目标、功能模块的划分、场景的组织、快速显示算法等作了详细的介绍。
the rendering algorithms based on the use of texture maps and piecewise approximate fresnel formula of reflection is proposed after analyzing the fresnel formula 同时分析了fresnel函数的特点,给出基于纹理映射和分段近似fresnel函数的水流渲染算法。
first, we will generate a virtual model by marching _ cube surface rendering algorithm, after we segment ct images . a simplified method is used to eliminate the ambiguity problem 本文首先由marchingcube面绘制的方法对实验的ct数据三维可视化,并提出了解决二义性问题的方法,得到虚拟模型。
in this dissertation, the definition of an appropriate and valid nested error metric sphere is presented, and a fast continuous lod terrain rendering algorithm is proposed 本文在定义了一种合理且有效的嵌套误差判据球的基础上,提出了一种快速的、视点相关的、连续层次细节地形表面绘制算法。
3 . proposing one data management and rendering algorithm based on the multi-threads, and with this algorithm realizing the rapid rendering of the real-time scene based on the missile coordinates 3、提出了一种基于多线程的数据调度绘制算法,利用该算法实现了基于导弹坐标相关的实时场景快速绘制。
