Polygon Morphing and Its Application in Orebody Modeling

Table 3

The main steps of our method of morphing nonplanar sections.

(1) Triangulate the source and target nonplanar sections separately.
(2) Transform the source and target nonplanar sections in 2D using the triangulations.
(3) Establish initial vertex for each transformed section in 2D.
(4) Approximate each transformed section in 2D with Fourier parameters.
(5) Interpolate the normals and centers of planes which have the transformed source and target sections in 2D.
(6) Interpolate Fourier parameters.
(7) Reconstruct the interpolated intermediate polygons.
