In 3D modeling, which term specifically denotes a single point in space independent of other geometry?

• A. Sub-object
• B. Segment
• C. Vertex
• D. ViewCube

Answer: (C)

A single point in 3D space is captured by a vertex. It’s defined by coordinates (x, y, z) and serves as a corner where edges and faces can connect, but by itself it doesn’t form a line or a surface. That independence—being just a position rather than a line or a surface—is what makes it the correct term. A segment is a line made from two vertices connected together, so it isn’t just a point. Sub-object refers to a selectable group of components (like vertices or edges), not to a single point itself. The ViewCube is a user interface element for changing the view, not a geometric element.
