1) Common lens holder 
A shading method in which a simple grid of lines is used to represent the basic contours of the underlying model. For many 3D artists, this is a favoured mode to work in, since it permits them to see faces and surfaces that would otherwise be hidden by overlying geometry.
A type of CAD model consisting only of lines and curves, in 2D or 3D. Wirefame models are not suitable for rapid injection moulding
the first stage in cgi 3D before an object is rendered. As the name implies, the imagery looks as though it is drawn in thin lines. As far less computation is required to represent wireframe images, they may sometimes be used to test animation timing
A stage in computer-generated imagery wherein the surface of objects is represented with polygonal l
