The visualisation of modern concert lighting requires complex illumination models to be calculated at interactive frame rates. Each light may have 20 or more parameters which are all changing in real time. Here we present a technique which allows static scenes with rapidly changing illumination to be re-rendered quickly in graphics hardware, with support for arbitrary geometry, complex BRDFs, shadowing and volumetric fogging. The rendering algorithm is re-factored to allow changing lighting to be applied to scenes which are otherwise fully rendered, minimising the calculation required when lights are moved.
