[vtkusers] [visualizing a volume]

[John Fourkiotis]

Hi,

i have used the following code to read 10 tiff image slices of a tooth,  
with each image having dimensions 250x188x8bits, (greyscale):

#include <vtk/vtkTIFFReader.h>

const int GREYSCALE		= 1;
const int TWO_DIMENSIONAL	= 2;
const int LENGTH			= 250;
const int WIDTH			= 188;

int main()
{
	vtkTIFFReader * tiffReader = vtkTIFFReader::New();
	tiffReader->SetDataSpacing(1,1,1);						// dont know what value is the  
correct
	tiffReader->SetFileDimensionality(TWO_DIMENSIONAL);			// 2-> to read a  
volume from 2D files
	tiffReader->SetNumberOfScalarComponents(GREYSCALE);			// greyscale
	tiffReader->SetDataScalarTypeToUnsignedChar();
	tiffReader->SetFilePattern("tooth%i.tif");
	tiffReader->SetDataExtent(0, LENGTH-1, 0, WIDTH-1, 1, 10);
	...
	return 0;
}//~

now, how can try to visualize the volume and see if my code does work ?  
Should i use a vtkImageToStructuredPoints and then create a volume ?

thanx
