Detailed Description

topologically and geometrically regular array of data

vtkImageData is a data object that is a concrete implementation of vtkDataSet. vtkImageData represents a geometric structure that is a topological and geometrical regular array of points. Examples include volumes (voxel data) and pixmaps.

int vtkImageData::ComputeStructuredCoordinates double  x[3],
int  ijk[3],

Gradient vector is computed by central differences (except on edges of volume where forward difference is used). The scalars s are the scalars from which the gradient is to be computed. This method will treat only 3D structured point datasets (i.e., volumes).

void vtkImageData::GetContinuousIncrements int  extent[6],
int &  incX,
int &  incY,
int &  incZ
 

Different ways to get the increments for moving around the data. incX is always returned with 0. incY is returned with the increment needed to move from the end of one X scanline of data to the start of the next line. incZ is filled in with the increment needed to move from the end of one image to the start of the next. The proper way to use these values is to for a loop over Z, Y, X, C, incrementing the pointer by 1 after each component. When the end of the component is reached, the pointer is set to the beginning of the next pixel, thus incX is properly set to 0.
