1. Primary Solids

The physical mass of an object is comparative to form. Form is three-dimensional and implies weight, such as a cube, cone, or sphere. Solid is one of the major states of matter. It is characterized by structural rigidity and resistance to changes of shape or volume.
Cube: A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids.

Cone: A cone is a three-dimensional geometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertex. More precisely, it is the solid figure bounded by a plane base and the surface formed by the locus of all straight line segments joining the apex to the perimeter of the base.

Sphere: A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a rounded ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point.

2. Dimensional Transformation

A form can be transformed by altering one or more of its dimensions and still retain its family identity. A cube, for example, can be transformed into other prismatic forms by altering its height, width, or length. It can be compressed into a planar form, or stretched into a linear one.

3. Subtractive Forms

When regular forms have fragments missing from their volumes are removed them as if they were whole and complete. We refer to these mutilated forms as subtractive forms.

4. Additive Forms

Centralizes Forms: Centralized forms require the visual dominance of a geometrically regular, centrally located form, such as the sphere, cylinder, or polyhedron. Because of their centrality, these forms share the self-centering properties of the point and circle.

5. Formal collision of geometry

Formal collision of geometry requires two different elements, such as circles or rectangles. It is combined and makes different geometry forms which make interesting shape.
