Read the passage and answer the question.

PASSAGE 2 (excerpt):

Geometric-modeling methods are a synthesis of techniques from many fields: analytic and descriptive geometry, topology, set theory, numerical analysis, vector calculus, and matrix methods, to name a few. Originally, only a loose ad hoc assembly, they have coalesced into an independent discipline with a well-defined language and logic.

We identify three distinct aspects of geometric modeling: (1) Representation: The physical shape of an object is given and presumed to be fixed; we compute a mathematical approximation once. (2) Design: We must create a new shape to satisfy some operational or aesthetic objectives. (3) Rendering: We usually need an image of the model to visually interpret it. These three aspects are, of course, closely related; for example, when we create the geometric model of a new product, at first, the model represents a physically nonexistent object. The model must be suitable for analysis and evaluation. After selecting a specific design, we can use its geometric model to guide the manufacture of the object.

Computer graphics, computer-aided design (CAD), and computer-aided manufacturing (CAM) have been the driving forces behind the rapid development of geometric-modeling schemes. Robotics, computer vision, and artificial intelligence are also making increasing demands on geometric-modeling capabilities.
