<div>Hello NG,</div>
<div> </div>
<div> I have used VTK for a while in the past, and I am re-starting now :-)</div>
<div>Basically, I have a 3D grid in which all the cell corners coordinates are specified (xyz for every corners => 24 coordinates per cell, every cell is an irregular parallelepiped). This kind of grid is usually called "Corner Point" in our field. 2 adiacent cells may or may not be connected, so for this reason all the corner coordinates are specified.
</div>
<div>What I would like to ask is:</div>
<div> </div>
<div>1) Once I have loaded all the coordinates in an array (I am using Python, but it doesn't matter), which is the most appropriate function/method to visualize this kind of grid? </div>
<div>2) Is there a particular way in which I should reshape the coordinates array (1D, 2D, 3D matrices) in order to speed up the loading/rendering?</div>
<div>3) During the visualization of the grid, most of the cells will be hidden because covered by other cell in front. Is there something I can do to speed up the visualization by somewhat "telling" to VTK that those cells are hidden or is VTK itself that takes care of this?
</div>
<div> </div>
<div>Thank you very much for your help and suggestions.</div>
