Question

How is a 3D computer model an abstraction of the real object it represents? What limitations might it have?

Answer 1

Answer:

A 3D computer model, is a graphic that portrays the idea of an object rather than the actual object in operation.

A 3D computer model is abstracts the real object by hiding the details which are deemed unnecessary, showing only relevant parts of the object to a person using the model

The limitations of the 3D models might have includes

1) The models are not subject to environmental constraints of a real object

2) The assembly of the model may be impractical in real situations

3) The materials for attaining the goal of the 3D model may be unavailable

4) The success or limitations to the complete operation of the model can not be readily ascertained from the graphics

5) The model cannot be used to develop further concepts easily

Explanation:

Answer 2

3D computer models helps in rendering real life objects or concepts in 3 dimensions, which is an upgrade from the previously used 2 dimensional space. 3D models could undergo transformation in the x, y and z coordinate.

Despite the advantages of 3D modeling as it allows reproduction of objects for may engineering, architectural and production purposes, it's still has some limitations which include ;

• 3D models lacks the originality portrayed by real life objects, this can be observed in the texture of the model.

• Exact reproduction of real life objects are impossible due to the impractical nature of models as they are only aided by software.

• Due to the possibility of model refinement, higy refined 3D models can be misleading as they may be aided with additions and features which may not be achievable in real life.

Hence, some limitations of the 3D computer models.
