What describes a Vertex in 3D space?

• A. A collection of vertices and connecting segments that form a line or curve.
• B. A subset of an object's geometry.
• C. A 3D navigation tool that also lets you switch between standard and isometric views.
• D. A single point whose position in 3D space is defined by coordinates.

Answer: (D)

A vertex is a single point in 3D space whose location is defined by coordinates. It serves as the basic building block of 3D geometry—edges connect vertices, and faces are formed by those connected edges. By moving or editing vertices, you reshape the model. In 3DS Max, vertices are where you directly manipulate the surface, often with additional per-vertex data like normals or texture coordinates. The other descriptions refer to lines, subsets of geometry, or the viewing tools, none of which define a single point in space.
