Hi.. Maybe a simple question (i'm a newbie ITK): I want to do a region-grow segmentation.I have an MRI bmp, a seed point (x,y,z), and a delta value (to control de region frontier). How can i generate a mesh?? Of course, this mesh will be connected to vtk.. Thanks in advance.. Saludos...Sebas.. sebasfiorent@yahoo.com.ar
