signed distance

常见例句

The algorithm fits the signed distance field of the source point set with an algebraic B-spline function and the zero set of the algebraic B-spline function is the constructed curve.
该方法用一个代数B-样条函数拟合原始点云的内蕴有向距离场，并以该代数函数的零点集所在的代数B-样条曲线作为重建结果。
And the traditional level set methods must re-initialize level set functions costly so that level set functions can be close to a SDF (Signed Distance Function) and image can be effectively segmented.
另外，在传统的水平集方法中，必须要进行复杂的水平集的重新初始化以确保水平集函数在迭代过程中保持为符号距离函数SDF，从而确保可得到一个有效的结果。
Using cache technology, by which the evaluated signed distance from vertices of the cell to the isosurface are saved and copied into its neighboring cells, can improve the efficiency of the algorithm.
采用缓存技术记录已处理过体元的顶点信息，避免了重复计算，从而提高了重建的效率。
