This applet generates the atom positions for nano-tubes and nano-cones. Its purpose is to give you the xyz-coordinates for use in other structure viewing programs. You may specify the chiral vector for nano-tubes and the disclination angle for cones. A value for ncone>1 will generate stacked cones with dZ as stacking distance. The calculation of the nano-cones might take a while depending on the specified cone height and disclination angle.The stereo-mode is for parallel-view. If you prefer the cross-eye view you may swap the sides of the images with a right mouse button drag, when in stereo mode.
