It is increasingly possible to render high fidelity 3D computer scenes in a reasonable time on modern computers. Accurate models and high fidelity visualisations of many natural environments are now possible for a wide variety of applications, including computer games and training simulations. This paper discusses a proof-of-concept of a pipeline for modelling and rendering of physically accurate virtual underwater environments. The following work is based on the three-dimensional modelling application Maya and the Radiance suite to provide high fidelity lighting visualisation of underwater environments for possible training scenarios.
