STEP BY STEP POLYGON MODEL EDITING
A Polygon mesh can be edited on a sub-object level (referred to as “sub-object editing”). The key principle behind this form of mesh manipulation is that the modeler has access to the basic structural components that form a mesh. These components consist of vertices, edges, and polygons that can be manipulated to alter the form of the mesh.
Vertices. A vertex is the most basic element of a mesh. Vertices are single structural points that define the corners of each face within the mesh.
Edges. Edges are the ...
