Environment Maps

Posted: October 31, 2011 in RayTracing

Added environment maps to be using as enviroment lights. Again, without enough samples, the results are quite noisy. Once way around this could be to use a blurred version of the map, such as using a lower level mipmap, another way is to importance sample the image, but this only seems to work well for low frequency maps. However, it does produce more interesting and realistic lighting, especially with reflective materials.
