1·Additionally, compared with the quadrangular slice, the width of triangular slice has a greater influence on the calculation speed of landslides.
另外,与四边形条块相比,三角形条块宽度的大小对滑坡速度计算影响较大。
2·Firstly, the surface was dispersed into quadrangular meshes, then, the self-hidden lines were removed from the surface by the algorithm of removing hidden lines.
首先将方程曲面离散成四边形网格,然后采用消隐算法消除曲面的自隐藏线。
