• Here are new versions of the glbox.cpp & glbox.h files with mouse control included. These files are exactly as at the end of lighting with the changes:

  • initialise the xTrans, yTrans & zTrans in the constructor.

    		      xRot = yRot = zRot = 0.0;		// default object rotation
    				scale = 1.25;			// default object scale
    				object = 0;
    				xTrans = yTrans = zTrans = 0.0; //init trans values
    		  

  • use gluLookAt() instead of glTranslatef() at the start of paintGL()

    		   gluLookAt(0.0, 0.0, 10.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
    		  

  • include the glTranslatef()'s in paintGL after the glRotatef()'s

        glRotatef( xRot, 1.0, 0.0, 0.0 ); 
        glRotatef( yRot, 0.0, 1.0, 0.0 ); 
        glRotatef( zRot, 0.0, 0.0, 1.0 );
    
    	 glTranslatef( -xTrans, 0.0, 0.0 );
        glTranslatef( 0.0, yTrans, 0.0 );
        glTranslatef( 0.0, 0.0, zTrans );
    
    		  

  • add the setXTranslation(), setYTranslation(), setZTranslation() and mousePressEvent(), mouseReleaseEvent() and mouseMoveEvent() to the bottom of your file.
  • I have drawn a simple phylotactic pattern instead of the now familiar cube
