A detailed 3D model was created to show the 500-million dollar construction project of a 10-mile section of I-95 at the Virginia / Maryland Border, it includes four multi-level interchanges and a major bridge (Woodrow Wilson Bridge) across the Potomac River. Using AutoCAD Land evelopment and 3D Studio Max 3.1, a multi gigabyte 3D database was created to engineering accuracy. The animation is 19,000 frames long and had to managed so that every time a change was made the project can be re-rendered, composited and posted in a 48 hour turn around, using five-dual 933 PCs.
