Perlin Texturing in ASTrace

I've added simplex noise volumetric texturing to ASTrace. I found this nice little Simplex noise class by Sjeiti and implemented it in the library. Simplex is slightly faster than Perlin noise in 3 and 4 dimensions so it is ideal to use as a volumetric texture for primitives in the tracer, here are a few examples:

As an extension I decided to create an animation using 4-dimensional simplex noise, just click on the image to launch it. I am planning on implementing a cloud sphere, and this would be ideal for animations of clouds:
