DSI Constraint to Approximate Data Using G1 Surfaces

@inproceedings{SegondsRM1997c,
 abstract = { Geophysical applications, such as raytracing, needs to use surfaces which are at least G1 (tangent plane continuity). We are presenting here a method to build such surfaces composed of Gregory triangles from GOCAD triangulated surfaces. Patches of the resulting surface are in one to one correspondence with the triangles of the original surface. Each triangle interpolates the three corners of the original triangle. Moreover. this method can take into account user defined constraints. For example, we will show here (Section 3.0) how we can approximate data points wlùle keeping the G1 continuity. },
