What makes up a 3D mesh
A 3D mesh is made with 5 different types of elements. They are vertices, edges, faces, polygons and elements
Vertices are the points of the 3D mesh. For example a cube,there are 8 points in the cube that are essential parts, the 8 corners. Each point are called the Vertex.
Edges are lines segment between two vertices points. For example in the cube there are 12 line segments and each of the line segments are edges.
Faces is connected by set of edges. Picture on the right shows a cube. In a cube each whole faces are made of 2 triangles. Picture on the right highlights them. Each triangle face are made out of 3 edges/line segments.
Polygon is plane figure that are bounded by finite chain of edges/line segments.
Surface is a 3D collection of points whose cross section is a curved surface, or the boundary of any 3D solid.
