1·At first the original data points are resampled using barycentric coordinates, followed by fitting the resampled data points.
该方法首先用重心坐标对原始的数据点进行重采样，然后对重采样得到的数据点进行拟合。
2·The barycentric coordinates of the plane view projection of a coal face are solved with a formula of geometric gravity centre.
利用平面图形几何重心公式计算回采工作面水平投影图形的重心坐标，然后根据影响传播角和开采深度计算下沉盆地中心位置的坐标。
3·Based on homogeneous barycentric coordinates, a new geometric variable, sharpness factor, is defined for measuring sharpness of independent vertexes.
基于齐次重心坐标，定义了新的网格顶点几何变量——锐度因子。
