Different 3-D Visual Elements and their Properties are listed below:
Volume:
Volume is a 3-dimensional element expressing height, width and depth. The boundaries of the volume are defined by surfaces. The properties of the inner mass are reflected in the movement and shape of the surfaces. These surfaces can be divided by hard transitions creating the boundaries of the planes. The boundaries/ edges represent the lines of the volume and the corners on the volume are the points.
Plane:
Is an elemental part of a volume. When the surfaces on a volume have clearly defined edges so you can discern its shape and contours, a plane is delineated.
Plane has lines and points as its elemental parts. A plane can also exist independently in space and is a 2-dimensional element expressing width and length.
Line:
Line is used to delineating the shape of a plane and the hard transitions between the surfaces as they form the edges of a volume.
Line has points as its elemental parts. An independent line in space articulates 1-dimension expressing length.
Point:
Is an elemental part of a line. It can be visualized as the start and end of a linear element and the corner points of a volume. A point has no elemental parts and no dimensional movement, yet it expresses position.
