基于三角带模板的车辙实时可视化方法

Real-time Visualization of Ruts Based on Strip Masks

给出一种基于三角带模板的车辙实时可视化方法,结合车辙的物理模型,并且采用过程纹理方法实时生成车辙纹理。先将地形分成大小相等的若干块,预计算一族三角带模板。在地形绘制时,仅是根据包围盒误差因子简单的选择一个三角带模板。选择Bekker的地形沉陷模型作为车辙的物理模型,并且采用过程纹理方法实时生成车辙纹理。给出了完整的动态地形可视化算法。最后实验证明的方法是可行、有效的。

A real-time visualization method of ruts based on strip masks was proposed, and the method combines with the physical based model of ruts and uses procedural texture to generate the texture of ruts. The terrain was partitioned into several blocks, and a set of strip masks of blocks was pre-computed. At run time, to render the terrain, it＇s simply to choose the mask of blocks that represents each part of the terrain to meet the desired visual fidelity. The physical based model of ruts, Bekker＇s Soil-Deformation Model, was combined with. The dynamic terrain texture is procedural texture. At last, the experiments prove that the method is feasible and valid.
