Class GraphicCell

java.lang.Object
chemaxon.marvin.space.GraphicCell
@PublicAPI public class GraphicCell extends Object
GraphicCell is a rectangular part of the OpenGL2 canvas containing GraphicComponents. Each cell has its own camera/viewing settings, own origin, clipping planes, and handling of viewing events such as rotation, zoom, shift, depth cue, etc.
Example of typical usage: 
 graphicScene.createNewCell();
 GraphicCell cell = graphicScene.getActiveCell();
 ArrayList molecules = graphicScene.readMolecule(moleculeFile.mol);
 GraphicComponent gc = molecules.get(0);
 cell.setTransformationCenter(gc.getId());
 gc.select();
 cell.hideSelectedComponents();
