| Abstract in different language: | One challenge in applying standard marching isosurfacing methods to sparse rectilinear grid data is addressed. This challenge, the problem of finding approximating gradients adjacent to locations with data dropouts, is addressed here by a new approach that utilizes a tetrahedral spline fitting-based strategy for gradient approximation. The new approach offers improved robustness in certain scenarios (compared to the current state-of-the-art approach for sparse grid isosurfacing). Comparative studies of the new approach’s accuracy and computational performance are also presented. |
