Quality Metric for Shadow Rendering

Shadow rendering is one of the most important aspects of rendering 3D environments, yet, the problem is far from trivial. A number of shadow rendering algorithms exist, with various degrees of rendering quality, fidelity and performance. Additionally, many of such algorithms offer high degrees of flexibility when it comes to fine tuning. This paper proposes a new method of measurement of quality of shadows produced by rendering algorithms, which method can be used for automation of algorithm choice and fine-tuning of such algorithms to specific data sets and use cases.
