The Guanella Pass Proposed Road Improvements Project CD-ROM is an early example of a multimedia CD-ROM created to present a visual comparison between an existing highway and prosposed alternatives. Created for Windows 95, this project was developed before many of the newer technologies discussed...
There are a few products available that allow the linking of a 3D CAD model to a schedule (Primavera or Microsoft Scheduler). These applications are commonly referred to as 4D tools. The tools are being applied more often to architectural and...
There are a number of analytical simulation tools used for testing roadway designs. The tools can be used to test capacity for a system, intersection and signal timing performance, or general traffic flow performance evaluation for a road network. Some of the more common tools are: HCS, CORSIM,...
Realtime interactive tools allow the user to navigate through a model environment at their own pace and to go wherever they want to go. Console games are a good example of interactive model environments. Objects in the scene can be set up for interactivity as well- the user can be allowed to...
2.5 D refers to visualizations that use a layer of animation over a static view where the base image doesn't change. These images are essentially photosimulations where one or more of the layers is animated. A good example would be a view of a road where the new road surfaces and the background...
The Bautista Canyon photosims are a good example of photosimulations produced with Microstation and a paint application. A 3D model of the road design was produced in Microstation, as well as the surrounding context as a 3D DTM. the road surface was texture mapped with an image of asphalt and...
This section discusses issues with exporting 3D Microstation files to other rendering programs, as well as some of the visualization techniques possible with those programs.
There are two key things to keep in mind when...
This section covers some of the more advanced paint techniques used for photosimulation and image retouching. The tools discussed are all in Photoshop. Camera matching is covered at the end of the chapter, the technique shown could be done in any 3D application that displays a background image...
This section introduces some very simple but innovative ways of presenting design data. These techniques require third party applications that are free or very reasonably priced. Links to vendors can be found in the Links section and demos are available by clicking on the indicated images (or...
