In this paper, a methodis proposed for reconstructing mountains from 3-Dimensional(3D) data obtained from the tracing of contour lines.
The thinning and the noise reduction are carried out after feeding the contour lines to the personalcomputer through image scanner. Then the 3D data of the points on the contour lines can be obtained from the tracing of the contour lines. Moreover, the 3D data of the points between the contour lines are calculated by using the linear interpolation and thelattice model based on the contour lines. Since these points are regarded as the vertices ofrectangular patch, the surface model using the rectangular patches can be reconstructed with hidden-surface and shading algorithms. |
