This paper presents a real-time visualisation of an early architectural design for an amusement park. This commercial project, aimed at generating political support and investor interest for the proposed development, was implemented to strict budgets and deadlines and provides the case study to analyse the limitations of current content creation tools and formulate requirements for further research and development. The architectural design of the amusement park was in its early stages at the beginning of the project. The visualisation team received a series of hand drawings from the architect representing the top-down view of the site including its immediate surroundings and a rough CAD model including building outlines. The development covers an area of roughly 1 km square, which is typical for many similar projects, although the team has previously handled real-time urban visualisations for larger regions of approximately 5 by 3 km. The amusement park is a parkland setting including green zones, transportation, pedestrian areas, large artificial ponds and a range of buildings representing different geographic regions and industries. The modelling team was tasked to visually enhance a basic block model provided by the architect to move away from the abstract look towards a "realistic" experience. This required a degree of guess-work and artistic freedom as the details of the architecture had not been specified at that point. This was a rather unusual project brief, as it required the modellers to make decisions usually left to the architect about the look of buildings. At the same time, it allowed the modellers to take a "game development" approach where design decisions were influenced by the polygon budget. Normally, the modellers are presented with fully specified CAD models that may need optimisation for real-time display. A rendering of the resulting model is shown in Figure 1.
