Abstract: The present invention relates to the importance-directed geometric simplification of complex mesh-based representations of objects in virtual environments for radiosity-based global illumination simulations. By means of simplification, the time needed to solve the radiosity equation and so generate an accurate physically-based simulation can be markedly reduced. Further, geometric simplification is performed during the global illumination simulation process rather than as a preprocess step.

Abstract: Monthly average DLI values for a specified geographic location, or a greenhouse, polytunnel or other controlled environment at the specified geographic location, are calculated from historic reference data from weather stations. The calculations are a prediction based on the geographic similarity of the specified location to the locations of the weather stations. Calculations may also be based on the proximity of the weather stations. Weather data from satellites may also be used. A calculation indicates whether a proposed controlled environment in a specified geographic location will provide sufficient monthly DLI for a given crop with known DLI requirements. Where the DLI is insufficient, an amount of supplemental electric lighting is specified.
