A method for rendering a drawing, including: identifying fixed objects (FOs) having footprints within the drawing; identifying moveable objects (MOs) having locations within the drawing associated with the footprints; identifying, within a coarse pixel array (CPA), coarse pixels corresponding to the footprints; setting the coarse pixels corresponding to the footprints to an occupied status; selecting a MO having a first location; identifying a first set of coarse pixels in the CPA corresponding to a first frame of the MO; determining that at least one coarse pixel of the first set of coarse pixels is in the occupied status; generating a second location for the MO; identifying a second set of coarse pixels in the CPA corresponding to a second frame of the MO; setting the second set of coarse pixels to the occupied status; and rendering the drawing by placing the MO at the second location on a page.
