Architectural Presentations Assignment Due Shadows cast on 4 elevations of the Playhouse and color scheme selected Session5 - Perspectives Today we will look at perspective drawing. We have mostly been working in orthographic views. Here are the differences: ORTHOGRAPHIC flat measurable We need to learn terminology. Some terminology refers to items located in elevation views. Others are located in plan. PERSPECTIVE vanishes non-measurable Home Planner Magazine Summer 1996, p.44 & 45 ELEVATION: Ground line - base where the object sits Copyright Microsoft Corporation 1983-2001 ELEVATION: Horizon line - intersection of ground/sky (where the eye is) Copyright Microsoft Corporation 1983-2001 1 ELEVATION: Vanishing point - where the lines vanish. It is always on the horizon line. Imagine straight train tracks or roads Copyright Microsoft Corporation 1983-2001 ELEVATION: True height line - the one place on out perspective where we can scale things our measuring stick Copyright Microsoft Corporation 1983-2001 PLAN: Picture plane - an imaginary plane where we are drawing what we see. Imagine a piece of glass we are drawing on. Depending where we put the glass will depend on what we see. PLAN: Station point - the place in plan where a person is standing. Since the cone of vision is between 30°to 45°, we position the station point in plan so the object is within the cone of vision. 30° 45° Jules Chiavaroli, AIA, NCARB AEC Drafting Fundamentals West Publishing Company 1994, p.110 (altered) Copyright Microsoft Corporation 1983-2001 PLAN: Cone of vision - 30°. Outside of that we get distortions. We can change the perspective view in a variety of ways: Copyright Microsoft Corporation 1983-2001 http://www.fotolog.net/dddo/?photo_id=8108214 2 Changing plan angle Changing our height (horizon line) Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p.176 Changing location of picture plane Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p.176 Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p.177 Changing our station point Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p.176 Follow along through the exercise of laying out the perspective. Look at handout for steps. Student should sketch along with slides. 3 4 5 6 7 Complete perspective on your own. Another way to quickly make a perspective is through perspective grids. Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p. 198 CAD programs can generate perspectives using 3D Models. Muller, Fausett, & Grau Architectural Drawing & Light Construction Prentice Hall 2002, p. 198 Assignment List By end of class period: - Perspective Handout completed - Everything due regarding the Project - Photograph model By beginning of next class period: - Be ready to organize the drawing 8
