Constructor Detail

MatchingViewer3D

public MatchingViewer3D(CleanMatchingResult result)
                 throws InvalidConfigParameterException

Constructor. When using this constructor, visualization will show automatically the volume, not the skeleton.

Parameters:

result - the matching result to be visualized

Throws:

InvalidConfigParameterException

MatchingViewer3D

public MatchingViewer3D(CleanMatchingResult result,
                        Config config)

Constructor.

Parameters:

result - the matching result to be visualized

config - holding configuration parameters

Method Detail

createSkeletonActor

private vtk.vtkActor createSkeletonActor(int[][][] cube,
                                         SkeletonObject so)

create an actor for a 3D skeleton cube. Each entry in the cube with a value higher than 0 will be assumed as skeleton point. The dimensions of the skeleton voxels are taken into account.

Parameters:

cube - - 3d array containing for each voxel index the skeleton information

so - - the skeleton object

Returns:

a vtkActor constructed from the information specified by the two parameters

SkeletonTo3DArray

private int[][][] SkeletonTo3DArray(SkeletonObject so)

Create a 3D cube from the specified skeleton.

Parameters:

so - the skeleton object to be encoded in 3d array

Returns:

3d array containing all skeleton information: Entries containing skeleton voxels are > 0.

createLineActor

private vtk.vtkActor createLineActor(Index index1,
                                     Index index2,
                                     Dimensions dim1,
                                     Dimensions dim2,
                                     int offset)

Create a vtkActor for a line.

Parameters:

index1 - the index of the starting point of the line

index2 - the index of the end point of the line

dim1 - the dimensions of the first skeleton object to be visualized

dim2 - the dimensions of the second skeleton object to be visualized

offset - the offset between the two skeleton objects

Returns:

actor constructed based on the parameters

show

public void show()

Show the matching result.
