      • isShowingSplices

        public boolean isShowingSplices()
        Check visibility of splices along cuts of the flattened surface.
        Since:

        23.07.03, 1.00 created (kp)

      • showSplices

        public void showSplices(boolean flag)
        Enable visibility of splices along cuts of the flattened surface. This enables to glue papers models to closed surfaces.

        Note, splices are only visible if the model is fully flattened. During all other states splices are automatically switched off.

        Since:
        JavaView 2.87.000
        Version:
        23.07.03, 1.00 created (kp)

        refold()

      • refold

        public void refold()
        Refold the geometry to its original position.

        unfold()

      • improveUnfolding

        public boolean improveUnfolding()
        Method to reduce the number of components the unfolding consists of. The method unfold must be called in advance.
