Groundplan

In some cases, coordination between the lighting and scene designer may result in a preliminary scenic groundplan that indicates not only all of the scenic and masking information, but temporary lighting positions as well.

You must learn to be ingenious in arranging groundplans. Always avoid the dull and trite—what may be called the no-room: that bare, three-walled room without architectural jogs for relief; that room with a routine selection and placement of furniture; that room with doors placed in balanced positions in the walls. New ideas about illustrating the action will present themselves to both you and the actors if you think and feel freshly about what makes up a groundplan.

It is also a tool for communication, both to your actors and your audience, because the way in which the groundplan shapes the space reveals much about the how the director and designers view the possible uses of the space, its owner(s), and its purpose. The groundplan provides you with the opportunity to create a variety of physical relationships among the characters onstage and shapes the possible patterns of movement that the characters might follow during the action.

Another method of recording blocking is to use a groundplan and numbered movements tracking sheet (see Figure 8.3).
