pic'ture plane"
the plane of a painting, drawing, or the like, that is in the extreme foreground of a picture, is coextensive with but not the same as the material surface of the work, is the point of visual contact between the viewer and the picture, and is conceived as a major structural element in the production of abstract or illusionistic forms.
