Wire-frame Model - Introduction

Introduction

Wireframing is one of the method of geometric modelling system. A wireframe model represents shape of solid object by its characteristics lins and points. There are two types of wireframe modelling.1)Pro's and 2)Con's. In Pro's user gives a simple input to create a shape. It is useful in developing system. While in Con's wireframe model, it does not include information about inside and outside boundary surfaces.Now-a-days in mechanical design wireframe models are used in defining complex solid objects. The designer makes wireframe model of a solid object first and then CAD operator reconstructs the object including detailed analysis. In this way a solid object is created indirectly by using wireframe technique. This technique has some advantage as follow-1)Generally the 3 dimensional solid objects are complex, wireframe model can be viewed in 1 dimension so this compactness helps designer.2)The solid object can be modified further. The designer can ignore the geometry inside surface while in solid modelling designer has to give consistent geometry for all details.3)Wireframe models require less space and also very few resources from CPU.
