Add perspective to your modeling

Clinician: 

Perspective is often used to add realism to our two dimensional painted backdrops. Museum diorama builders extend perspective to their three dimensional models as well. Although this technique is rarely used in model railroads, Kermit will show you how it can enhance your railroad's visual appeal.



The clinic will include historical background and principles of both two and three dimensional perspective. True perspective modeling is more than just placing objects of different scales behind each other in a scene. Many computer based drafting programs include a perspective feature making it easier to produce suitable model drawings compared to older manual drafting methods.



Examples will be included to illustrate how three dimensional perspective modeling can make your layout seem much larger than it really is.
