<div dir="ltr"><div><div><div>Hi All,<br><br></div>  I am trying to overlay a 3D color image (maybe from the segmentation or color mapping) on a 3D grayscale image (original image) and display the overlayed result using vtkImagePlaneWidget. How exactly should I achieve this? I searched online. Some people use vtkImageStencil or vtkImageBlend to combine them before set it to the input of vtkImagePlaneWidget. But these two filters run pretty slow (~15 seconds) on my 3D datasets. Are there other ways?<br>
