3D Visualization

Introduction

As computer technology continues to impact the lives of people, the manufacturing of an increasing number of products are the result of computer generated imagery (CGI). CGI is a valuable application in all forms of multi-media presentations from TV to the internet - in fact any media that uses a display screen or panel. The technology allows viewing of design outputs either through the production stage or as a finalized presentation relinquishing the need for bulky equipment to convey a product, promotion, idea, or concept.

3D Visualization

Architecture and engineering services have greatly
benefited from the development of computer
graphics. Graphic representation or CGI in a
textured 3D format makes it easy to convey the idea of what would merely be a collection of lines and text on a piece of paper into a format understood by everyone, an image. 3D Visualization offers the freedom both for the client and the service provider to communicate within a media that they both understand and share. With 3D Visualization, a window is opened that will allow concerned parties to know how objects will appear and behave as though they were already in existence. Applied appropriately the technique may save considerable planning and construction costs since planning and design processes can be shortened just as the need for re-construction of architectural / structural features can be minimized.

3D Visualization Process
The creation of a 3D image is a relatively
straightforward process reiterated in key areas to
allow for refinement to arrive at a photorealistic
finish.

Input

Input to the process can be either in the form of an electronic (CAD) or handmade sketch in 2D. The initial drawing or product data ensures that the 3D model is as precise as it can be to the detail required by the Client. This constitutes the basic wireframe representation that would guide the 3D model.

Modeling
Based on either scanned or drafted drawings, or
photographic references, a three-dimensional
model is created through the use of a modeling
application by recombining 2D information.

Software used for this initial stage may include
ArchiCAD, Autodesk Inventor, 3D Civil, ABS, ADT, Revit and others. Models can be made utilizing primitive 3D objects including certain deformations,spline extrusions, lofts, and booleans among other more advanced modeling techniques to produce an initial wireframe representation of the object.
