This image (which is part of a series) was created for showing the final client in Dubai the complex light design created by renowned lighting engineers in Berlin for this very tall skyscraper.
I first had to create a complete and very detailed solid model in formZ (around 6 million polys) of the building, using the original AutoCAD DWG plans and a rough Sketchup model for reference and orientation. The detail was needed for getting a simulation result as close as possible to the real lighting. Once the light design was completed by the engineers, it was transferred into LightWave by setting up a complex light rig made of around 1.500 spot and area lights. The Luxigon technology in LW was used to place lights using random selected polygons inside the apartments.
The final rendering was done in radiosity mode with Worley's FPrime 3.2, which was also indispensable when used as a real time render preview for setting up the different light rig parts.
Final render resolution was 6000 x 3000 pixel, and each image was rendered overnight on an 8 core Mac under WIndows XP64 with 8 Gbyte of RAM.
