In 3D computer graphics, the term "vertices" (also known as "verts") refers to the points in a 3D mesh that define the shape of an object. An edge is a line segment that connects two vertices, and a face is a flat surface formed by three or more edges.
For example, if you were to model a cube in a 3D modeling software, the vertices of the cube would be the eight corner points of the cube, the edges would be the 12 line segments connecting the vertices, and the faces would be the six flat surfaces formed by the edges.
Vertices, edges, and faces are important concepts in 3D modeling because they define the shape and topology of an object. They are used to create the geometry of a 3D model, and they can be manipulated to alter the shape and appearance of the object.
In summary, vertices are the points that define the shape of an object, edges are the line segments connecting the vertices, and faces are the flat surfaces formed by the edges. Together, these elements make up the basic building blocks of 3D models.
