Figure 4

Example of the strategy used to reconstruct the target geometry by means of isoparametric transformations: (a) definition of the patch in the - domain used to cover the target geometry; (b) definition of the initial control points (CPs) of the isoparametric transformation; (c) initial geometry to be mapped; (d) placement of the final CPs onto the target geometry and sequential application of the isoparametric transformations; (e) final mapped geometry. The top part of the figure shows how the same patch is differently deformed using different isoparametric transformations (quad 4, quad 8, and quad 9).
