A mesh is made up of which three elements?

• A. Points, Lines, Surfaces
• B. Vertices, Triangles, Normals
• C. Vertices, Edges, Polygon Faces
• D. Wires, Cells, Polygons

Answer: (C)

In 3D meshes, the shape is defined by three fundamental building blocks: vertices, edges, and faces. Vertices are the points in space that mark the corners of the shape. Edges connect pairs of vertices to form the skeleton or wireframe of the model. Faces, or polygon faces, are the flat surfaces bounded by edges that fill in the shape and define its visible surface. Together, these elements describe the mesh's topology and are what rendering systems use to draw the object. The option that lists vertices, edges, and polygon faces matches this foundational structure. Other options either mix in shading attributes like normals, which aren’t core topology, or use nonstandard terms that don’t represent the usual mesh components.
