InflateContour
Maps a contour according to a transform defined by the corrospondences of the faces of two homologous shapes.
Description
The
InflateContour prgram is inverse of the application
MapContour. Given a contour, presumed to be flattened by
MapContour , and the original 3d surface and mapping file used by
MapContour, the vertex coordinates of the contour are "inflated" from a 2d space into the original 3D space.
The program requires these inputs:
- A original shape input file.
- A file contains contour.
- Output file name.
Method
Each vertex of a contour is treated as follows:
- The face of the 2D flatten surface (presumed to contain the contour) that contains the vertex is located.
- For this face, find vertices of 3D face which is transformed from the original.
- Using vertices of the original face and vertices of flatten face, find transformation.
- Transform the point on the contour using this transformation.
