Hi, <div><br></div><div>I am also interested on this topic. </div><div><br></div><div>My question is, how can you achieve 10-bit display when vtkImageActor requires data to be of unsigned char type? (<a href="http://www.vtk.org/doc/release/5.6/html/a00819.html">http://www.vtk.org/doc/release/5.6/html/a00819.html</a>) This means data is cut down to 8-bit, so the resolution is already lost though your vtkImageData were of short type (2 bytes).</div>

Hi Mark,<br>
<br>
Some (maybe most?) 10-bit displays use a 24-bit RGB to 10-bit<br>
greyscale conversion. In other words, they are designed to work with<br>
standard 24-bit frame buffers and 24-bit DVI cables. The 24-bit to<br>
10-bit conversion may vary from manufacturer to manufacturer, but the<br>
basic idea is that you can achieve 10-bit display simply by applying<br>
the correct RGB lookup table in VTK when displaying the image.<br>
<br>
Is there a specific 10-bit monitor that you are planning to use?<br>
<br>
