Grasshopper3d plugin for the definition of stadium and auditorium geometry and analysis of spectator view quality. The plugin implements the 'cValue' sight-line method to generate geometry which is standard in UK (HMSO 2008) and European stadiums. The plugin is built from a new c# library that integrates geometry generation and analysis methods for stadiums and other event spaces.
Toro currently handles a range of bowl layouts and comes with a set of analysis tools for examining cValue, aValue and eValue across all spectators in the generated stadium, providing output graphics and values that can be used to generate a colour scale result mesh.
cValue analysis determines not only the cValue for each spectator but also allows for a range of different methods to locate the view focal point
aValue is a measure of the percentage of the area of the projected pitch in the spectators view cone. The method supports a simple and ergonomically defined view cones, and allows the projected results ptich and view cone to be output as polylines. aValue analysis also measures the amount of obstruction by the heads of spectators in front. (See Hudson and Westlake, (2015) for detailed description of the aValue).
eValue analysis determines simple metrics in order to understand spectator comfort, in terms of torsion between the direction defined by the seat and the centre of pitch and horizontal and vertical angles to the limits of the playing area. Results can be generated numerically and graphically.
