Blending projectors is also a significant challenge on a model like this. For each given pixel of the 3D surface texture, there are a bunch of factors that should drive the decision of how much light is best to take from each projector, to achieve a uniformly lit result using the best quality available pixels. Some model surfaces have one projector hitting them, while others have two, three, or four. Each lens will be a different distance from each given surface, and each lens may have a different field of view, resulting in differences in brightness across the model.

Each lens also has a depth of field, and an incident angle at which it hits each given surface, resulting in brighter and less smeared pixels on one surface versus the next. This decision process is managed by an emerging Autoblend tool that will become available officially with our next generation software release. We used an early implementation of this on The Egg with great results.

With the detail of the client’s vision and the unique surface that we were working upon, we felt that the Delta Media Server platform was the only choice for a reliable and configurable server for this creative project. The team at 7thSense helped deliver a solid and reliable system, whilst also keeping a flexible platform for the artists to work upon.
