Ok, I define the contour as following : src = mlab.pipeline.scalar_field(im) src.update_image_data = True contour = mlab.pipeline.contour(src, ) contour.filter.number_of_contours = int(im.max())
with im.max = 1041 labels Then : connect_ = tvtk.PolyDataConnectivityFilter(extraction_mode=6, color_regions=True) connect = mlab.pipeline.user_defined(contour, filter=connect_) surf = mlab.pipeline.surface(contour,colormap="gist_rainbow") If I use "extraction_mode=6", it display only one region. With "extraction_mode=5" it display : connect_.number_of_extracted_regions = 697, so I haven't all regions. And finally, when I try to use the picker, I can't update the color of the picked region.
