<br><br>I would like to visualize the entire data set and have a single object stand out by rendering it with a different color than the rest of the objects. For example, I would like object 1 to be red and objects 2 and up to be white (black background).
<br><br>The data set is large enough to where volume rendering performance is very slow, so I have been surface rendering instead. I am able to read the image in using ITK and get the voxel values. In order to render the surface, I've used the itkImageToVTKImageFilter to convert the image to VTK.
<br><br>Is there a special filter that would be good for doing this? Or does anyone have any insight as to how I should approach this?<br><br>Thanks in advance for any help!<br><font color="#888888">-Jake<br></font><br>_______________________________________________
