Geologic Surface Reconstruction Based on Fault Constraints

Some applications in 3D mesh surface modeling, e.g. geologic surface reconstruction, require linear discontinuous mesh pieces reconstructed from input point cloud. Unfortunately as far as we know, those previously developed approaches failed in reconstructing such mesh directly from point cloud. This paper presents a new method which using mesh fitting to create discontinuity during geologic surface reconstruction. After improved Hoppe´s reconstruction method, each vertex located at discontinuous area is adjusted to a new position based on quadric error metrics. Experiment results show that our method could generate high quality surfaces which satisfy both geometric and geologic constraints.
