Method V indirect light

Created by davidbrinnen

Thanks to Horo for his test scene and some excellently presented information which has been invaluable in progressing this interesting project. So here we are again in indirect light simulation land. This comprises a number of ideas and techniques picked from Horo's, Rashads and my own experiments. The coloured reflected light component utilises a form of the bsolutions process. The ambient light component I made by filling the room's space with 256 randomly placed weak white light sources. This render provides an ambient light map (grey scale) to direct the coloured reflected light and some fake ambient light - this is done via a filter (a bit like the bake light) directly in front of the camera which fuses the light information and the colour information together. The final render took just under four minutes, that being the direct light source viewed through the filter. The filters took about fifteen minutes each to render. Good points for this method is that it is relitively quick in terms of render time, handles ambient and colour reflection. Bad point is that materals have to be changed to make the colour reflection filter component. The results don't look too bad to me.
