Project 03.3 Projections: Digital Perspective

March 6, 2013

Introduction

In the third part of our exploration into projections you will learn how to create two dimensional representations of three dimensional digital models of spaces extracted from plans and elevations. You will work with the spaces in your perspective drawings from part 3.2 and use your orthographical survey drawings as reference to create accurate digital 3D models using Rhinoceros 3D. These digital models will then be used to produce a series of spatial drawings and images.

From a digital 3D model a range of different types of 2D representations can be created. You will first learn how to produce line drawings in orthographic projections from the digital model resulting in plans, sections and isometric drawings. Then line drawings in perspective projection. Here we will look for the same station points you used in your perspective drawings from part 2.

These black and white line drawings will accurately represent the dimensions and proportions of the space, but not light, colour and texture. Modern digital 3D software have powerful rendering engines that can manifest light and texture at great accuracy. You will now go back to your sites and collect photographic documentation of the surfaces of your space. These will then be manipulated in Photoshop so that they are perfectly orthographic representations of the surfaces. These image files will then be “mapped” as textures onto the surfaces of your digital model so that perspective of the space can be created that closely resembles the original. Only now you can change the lighting, or time of day.
