Documentation

This class implements a piece-wise affine warping between two shapes using a Delaunay Triangulisation of the source shape. This triangulisation is the used for both the source and destination shape. The corrospondance between points and triangles gives a continuous deformation field inside the triangles. Since the deformation is performed on a linear per-triangle basis, the field is not smooth across triangles.

CAAMMesh m_Mesh

The Delaunay Triangulisation of the source or dest shape

std::vector<CAAMPoint> m_vDestPoints

The points of the destination shape

bool HasSrcShape() const

Returns true if the source shape has been set

CAAMWarpLinear( bool useSrcDelaunay )

Constructor.

Parameters:

useSrcDelaunay - If true the Delaunay of the source shape is used.

Returns:

Nothing.
