Perspective Projection
Engineering Graphics (EG)
Perspective projection is an another way of representing an object on a plain paper. So far we have seen orthographic projection and isometric projection.
Chapter - 18 Perspective Projection At the end of this chapter we will be able to: 1. Define perspective projection. 2. Distinguish between perspective projection and orthographic projection. 3. Understand the different types of perspective projection. 4. List out the methods of drawing perspective projection. 5. Draw the perspective projection of plane figures by visual ray method and vanishing point method. 6. Draw the perspective projection of simple solid figures by visual Ray method and Vanishing point method. Perspective projection is an another way of representing an object on a plain paper. So far we have seen orthographic projection and isometric projection. In orthographic projection, object is projected by parallel rays and the image of the object is assumed to deposit on a transparent plane. The object is looked from three different directions and the multiview of the object is normally prepared for better understanding. In isometric projection a single view is used to represent a three dimensional object by using three isometric reference axes. Since the object is drawn in tilted position, each and every measurement along isometric axes is foreshortened by 0.816 times of the original dimensions. Now we will see the perspective projection, an another way of drawing the given object in a single view showing all the dimensions of an object, length, breadth and depth.INTRODUCTION
