Is this a bad idea for bouding boxes?

[American2050]

So, I'm making a block that based on different values, it changes the bounding box.

 

The idea is a block that starts with just a center cube of 6x6x6 and each time it has a neighbour block to conect to on some side it adds a cube to connect to the block next to it.

 

I came with this, but not sure if it's a good idea, or if it should be done in a different way.

 

Pixel is: final static double PIXEL = 1D/16D;

state = state.getActualState(source, pos);
    	
    	double initX = 5*PIXEL;
    	double initY = 5*PIXEL;
    	double initZ = 5*PIXEL;
    	double finalX = 11*PIXEL;
    	double finalY = 11*PIXEL;
    	double finalZ = 11*PIXEL;
    	
    	if (((Boolean)state.getValue(UP)).booleanValue()){
        	finalY = 16*PIXEL;
        }
        if (((Boolean)state.getValue(DOWN)).booleanValue()){
        	initY = 0*PIXEL;
        }
        if (((Boolean)state.getValue(NORTH)).booleanValue()){
        	initZ = 0*PIXEL;
        }
        if (((Boolean)state.getValue(SOUTH)).booleanValue()){
        	finalZ = 16*PIXEL;
        }
        if (((Boolean)state.getValue(EAST)).booleanValue()){
        	finalX = 16*PIXEL;
        }
        if (((Boolean)state.getValue(WEST)).booleanValue()){
        	initX = 0*PIXEL;
        }
    	
    	return new AxisAlignedBB(initX, initY, initZ, finalX, finalY, finalZ);

 

If you need a more graphical representation of what this block looks like let me know.
