A recognized weakness of existing billboard cloud algorithms is their lacking ability to simplify animated models. In this thesis we focus on the simplification of animated polygonal tree models, and our goal is to improve the billboard cloud technique with our own solutions for simplification of the animation of polygonal tree models; an extension we refer to as animated billboard clouds.
We present two solutions for simplification of animated tree models. The solutions use our own implementation of a billboard cloud algorithm developed by Lacewell et al., specifically aimed at the simplification of the foliage of static polygonal tree models. In order to evaluate the visual fidelity of an animated billboard cloud model we define a set of error metrics that enable us to objectively measure the quality of the simplification.
A prototype implementation of one of the solutions has been created as part of the project. This implementation, along with our implementation of the chosen billboard cloud algorithm, will be tested and evaluated.
