For Graphics I need to model the shape and the radiance profile of an existing light bulb in order to use it in a ray-tracing application. I can freely choose the light bulb. The strategy must not be very detailed or very long, just a few lines. As most light bulbs don't offer the radiance profile, I wondered how to construct it from the given specifications. I'm allowed to make some assumptions.
It would be of great help, if someone can guide me in a good direction.
