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

Convenience function computes the structured coordinates for a point x[3]. The voxel is specified by the array ijk[3], and the parametric coordinates in the cell are specified with pcoords[3]. The function returns a 0 if the point x is outside of the volume, and a 1 if inside the volume.

void vtkImageData::GetVoxelGradient int  i,

Given structured coordinates (i,j,k) for a voxel cell, compute the eight gradient values for the voxel corners. The order in which the gradient vectors are arranged corresponds to the ordering of the voxel points. 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.
