使用具compact support 特性的Wendland，透過影像對應點及攝影機間的相對方位計算出三維座標點，並將此座標點影射到一球面上以計算Wendland的係數，以產生場景之三維表面模型。
We use Essential Matrix to compute the relative orientation between cameras.
We use Wendland radial basis functions with compact support to compute 3-D coordinate by image corresponding points and relative orientation between cameras. Then we map the coordinate points on a spherical surface to compute the coefficients of the Wendland functions. We can then generate a 3-D surface model of the scene.
