Svet,
Geoshapes in GMF project has 3D rectangle, maybe that is what you are
looking for. I've pasted the code below in case its' useful.
Hope that helps,
Tas.
public class GeoShape3DRectangleFigure extends GeoShapeFigure
implements IPolygonAnchorableFigure {
/**
* Constructor - Creates a 3D Rectangle with a Default size
*
* @param width initial or preferred width of the figure
* @param height initial or preferred height of the figure
* @param spacing <code>int</code> that is the margin between children in
logical units
*/
public GeoShape3DRectangleFigure(int width, int height, int spacing) {
super(width, height, spacing);
}
/* (non-Javadoc)
* @see org.eclipse.draw2d.Figure#paintFigure(org.eclipse.draw2d.Gra phics)
*/
protected void paintFigure(Graphics g) {
List points = computePoints( getBounds() );
PointList outline = new PointList();
for( int index = 0; index < 6; index++ ) {
outline.addPoint( (Point)points.get( index ) );
}
Point p2 = (Point) points.get( 1 );
Point p4 = (Point) points.get( 3 );
Point p6 = (Point) points.get( 5 );
Point p7 = (Point) points.get( 6 );
// Draw the shape with the fill color
g.fillPolygon( outline );
// Draw the shapes outline
g.drawPolygon( outline );
// Draw the remaining lines
g.drawLine( p6, p7 );
g.drawLine( p7, p4 );
g.drawLine( p7, p2 );
}
private List computePoints( Rectangle rect ) {
List toReturn = new ArrayList();
int scaleWidth = (int) (rect.width * 0.25);
int scaleHeight = (int) (rect.height * 0.25);
Rectangle r1 = new Rectangle( rect.x, rect.y, rect.width - scaleWidth,
rect.height - scaleHeight );
Rectangle r2 = new Rectangle( r1.x + scaleWidth, r1.y + scaleHeight,
r1.width, r1.height );
Point p1 = new Point( r1.x, r1.y );
Point p2 = new Point( r1.x + r1.width, r1.y );
Point p3 = new Point( r2.x + r2.width - 1, r2.y );
Point p4 = new Point( p3.x, r2.y + r2.height - 1 );
Point p5 = new Point( r2.x, p4.y );
Point p6 = new Point( r1.x, r1.y + r1.height );
Point p7 = new Point( p2.x, p6.y );
toReturn.add( p1 );
toReturn.add( p2 );
toReturn.add( p3 );
toReturn.add( p4 );
toReturn.add( p5 );
toReturn.add( p6 );
toReturn.add( p7 );
return toReturn;
}
/* (non-Javadoc)

public PointList getPolygonPoints() {
List points = computePoints( getBounds() );
PointList outline = new PointList();
for( int index = 0; index < 6; index++ ) {
outline.addPoint( (Point)points.get( index ) );
}
// Close the polygon
outline.addPoint( (Point)points.get( 0 ) );
return outline;
}
}

Thank you Tas!
I have taken the paintFigure method with all the dependant methods from
GeoShape3DRectangleFigure class and it worked perfect for me.
