Which term refers to a single point whose position in 3D space is defined?

• A. Segment
• B. Viewport
• C. Vertex
• D. Spline

Answer: (C)

A vertex is a single point with a defined position in 3D space. In 3D modeling, a vertex marks a corner of a polygon or mesh and is specified by coordinates (x, y, z). This makes it the fundamental building block for shaping geometry, since edges and faces are created by connecting vertices. A segment, by contrast, is just a line between two vertices; a spline is a smooth curve defined by multiple points; and a viewport is simply a window to view the scene. So the term that uniquely describes a single point in 3D space is vertex.
