AU such shi I first as flat surfaces their external contour must be defined by the mind to identify it as being one kind of shape or another and subsequently what meaning that shape might have. The more active the plane s contotir-and more so if the contour becomes concave allowing surrounding negative space to enter into the dimen sional surface defined by the shape the more dynamic the shape will appear and the less it will radiate and focus ill the way a dot with a simple undifferentiated contour IIt I - The relative s plicity of the shape has an impact on its perceived mass or weight. A large form with a simple contour retains its dot like quality and presents a heavy optical weight a form with a complex contour and a great deal of interaction between internal and external positive and negative areas becomes weaker more line-like and exhibits a lighter mass. As soon as texture appears on the surface of a plane its mass decreases and it becomes flatter unless the texture emulates the effect of light and shade creating a perceived I hree-dhuensionality or volume liven though apparently three-dimensional the plane or volume still retains its original identity as a dot. A plane with a sirtlple contour A appears heavier has more mass than a plane with a complicated contour B . Both planes appear even lighter when they take on surface texture. The simple plane with texture C appears lighter than the solid more complicated plane the textured complicated plane D appears lighter still. to advance however because of its perceived greater weight Overlapping the solid plane with the textured plane creates an ambiguous tension between foreground and background. A plane whose texture emulates the effect of light and shade appears to have volume. A plane .
