>=Creating real 3D terrain in real time based on the elevation data is often required in visual simulation. A kind of modeling method is proposed based on weighted average algorithm. The elevation of a random point in the known point mesh is calculated according to its near two layers of mesh vertices. The distances between the pending point and the mesh vertices are taken aa the weights. To rectify the model, the linear extension elevation of mesh vertices is inducted into the formula. Then, the mesh is subdivided through double third-order spline interpolation, and the terrain is generated by using OpenCL triangle instruction. The model is fit for the smooth terrain. The results show that the terrain model is calculated in real-time and the 3D terrain accords with the real topography.

视景仿真工程应用中常需要根据给定的地形高程数据实时生成真实的三维地形。基于加权外推算法建立了一种的地形几何模型。对于已知高程点网格中的任意点,由其外围两层网格点的高程信息推导其高度,以已知点距所求点的距离为权重系数;并将已知点的线性外推点信息引入到加权公式中以修正模型。通过双三次样条插值细化网格顶点,并利用OpenCL指令函数将风格顶点依次相连生成三维地形。此模型适合于起伏平缓连续的地形。应用结果表明:满足逼真度、实时性要求,生成地形符合真实的地形走势。
