Hello, I'd like to cut a quarter out of a hollow sphere, so that I can see the interior empty sphere. The data is provided as one column (with 0 at empty space), my .general file looks like this: ============================== file = hohlkugel3d.data grid = 128 x 128 x 128 format = text interleaving = field majority = row structure = scalar dependency = positions type = float positions = regular, regular, regular, -1.000000, 0.015748, -1.000000, 0.015748, -1.000000, 0.015748
end ============================== excerpt of hohlkugel3d.data: 0.000000 0.000000 0.000000 1.000000 1.000000 1.000000 0.000000 Could somebody give me a hint how to this? I tried it using the VolumeClip example, but there a two problems: 1. ClipVolumenMacro always clips a complete plane; joining two of them therefore leaves with me only a quarter of my orginal sphere whereas I only want a quarter clipped. 2. I am unable to map the zero values to black colour (I guess "ShowBoundary" is responsible for this - but I need it for the "ClipVolumeMacro", don't I?). Regards Thomas
