Shape, Volume and Object
Object
Shape
A shape is defined by Oxford Dictionary as the external form, contours, or outline of someone or something. Therefore, by definition a shape can be an open shape or closed shape. Open shapes include lines and angles. Closed shapes include triangles, squares, rectangles and other polygons. If any of the closed shapes are made up of open shapes then the closed shapes are said to be ill-formed shapes. If the closed shapes are holistic and complete in nature, they are called well formed shapes.
In TAD all shapes are well formed shapes.
Volume
A volume is defined by Oxford Dictionary as the amount of space that a substance or object occupies, or that is enclosed within a container. Traditionally a volume is associated with a solid object that has mass.
In TAD, even voids are objects. Hence, the void space within a room has a volume.
