Smoothing 3D Geological Models Based on Controllable Morphing
In this paper we present a new method for smoothing 3D geological models from several sets of cross-sections, based on our proposed controllable morphing algorithm. Before the construction of 3D geological models, intermediated cross-sections are interpolated from pairs of adjacent cross-sections with the constraint of other directional cross-sections, and then smoothing models are created from all of these cross-sections. And creation of intermediated cross-sections is mainly transformed into the creation of intermediated geological boundary lines which are inside the cross-sections, based on the controllable morphing algorithm. This method can construct not only naturally and continuously smoothed geological models for characteristics of morphing technology, but also more real models for using other directional cross-sections as constraint. In the implementation of the algorithm, we firstly introduce four typical constraint modes: no constraint mode, boundary constraint mode, mid constraint mode and composite constraint mode. And other complex modes can be transformed into these four modes. Finally, an example has been conducted to validate the method.
