A physically based renderer that will be able to calculate photosynthetically active radiation and usable radiation in aquariums. I'm into planted tanks. Currently I'm mostly programming the render part and decided that a stochastically progressive photon mapper is good enough and will make it easy to calculate the intensity and reflector efficiency and also get a photo realistic render of the tank. I'm using Java3D to grab/create the geometry and parts of pbrt in my own sppm-implementation. Here is the latest result: http://www.flickr.com/photos/defdac/5513265646/ http://www.flickr.com/photos/defdac/5513265646/ Don't know if it is startup material though? It's a hobby but I would really love working with light calculations or combine my knowledge about plant physiology, electro magnetic radiation and graphics programming.
