I meant total illumination.
The aim of this is to get the radiance from a virtual sun on a virtual planet, at any point on the planet. But I believe there could be many more uses.
I imagine you could scan your scene for all lights, test if the point is within the bounds of each light and compute the "illumination".
Sure, I just expected to get the already computed result from the J3D internal renderer equation instead of doing the work myself and having to plug it into the class hierarchy.
By the way, I just noticed reading the doc once again that I can set up any intensity parameter from which I could define the actual brightness of a light source. I wondered why this hasn't missed me so much before already.
Of course, I meant "can't set up intensity".
