Solid modeling

The volume model is an extension of the surface model, which allows for additional construction requirements, the description of a volume.

Geometrical Meaning

Instances of a solid model created in a virtual space. Such an object ( = solid ) has a closed envelope which the clear definition of inside and outside allow it ( see also Möbius band). This makes it possible to check a collision between objects. The volume can be modeled directly or indirectly:

• Direct representation schemes construct the volume of simple primitives. Examples are the decomposition model ( Volumetric model ) or the Constructive Solid Geometry (CSG ) model, which uses the construction of complex body of simple, parameterized primitives Boolean operators.

• Indirectly, the volume is described by its envelope. The typical representative is the boundary representation (B -rep ) model that defines the bounding surfaces on corners, edges and surface geometry. The description of the shell is done with flat or arbitrarily shaped surfaces ( free form surfaces ).

Solids can be assigned properties. Result, the volume model is extended to the product model. For example, by assigning a density, the mass of the body - are calculated - dynamic, depending on the volume.

Other meanings

As a volume model much selling vehicle models are referred to in the motor vehicle sector, which account for the majority of sales of the vehicle manufacturers, in contrast to a niche model. For example, the VW Beetle was a solid model, while his successor VW New Beetle and VW Beetle are only niche models.
