<div dir="ltr">Hello,<br><br>I want to calculate all voxel ids of a vtkImageData that intersect with the bounds of a tetrahedron of a mesh.<br><br>My idea, with vtk averages, is that I compute the structured coordinates of the two boundary points an set the extent of the image to that points. Now I can get all cells of that extent to extract some kind of data (e.g. scalars), but I want to know the id of the cell of the whole extent.<br>
<br>Whats the best way to get this id's?<br><br>Greeting<br></div>
