Hi!!!<br>I'm trying blending multiple images with VTK,<br>but they're disappearing.<br>I saw vtkImageBlend join perfectly two images, when I join <br>more image, the initial images are disappearing.<br>I note in vtkImageBlend's Code,&nbsp;when&nbsp;I&nbsp;modify&nbsp;the&nbsp;second image's opacity,
<br>the&nbsp;first image's opacity changes too.<br><br>Another problem, it's I don't know how to get a shape from vtkImageData,<br>because they stay in diferent&nbsp;levels&nbsp;(altitude). So&nbsp;when&nbsp;I&nbsp;try&nbsp;blending&nbsp;the&nbsp;images,<br> they're not joined.
