XL7 Radiosity/Caustics

A few quick experiments:

Using the XL7 Demo on a 1.37GB G4/450 with OS9.1.

A prism displayed using caustics, and a little hack involving motion blur:

Click here for a description of how the scene was set up. The scene motion blur technique darkens the spectrum, but this can be helped a little bit by increasing the saturation in post. The shot above is a screen cap right from the render window. If anyone has suggestions on how to show spectra in animations or how to boost the saturation in the original render, please . Not sure why there's banding from the dim fill light in the lower left.

I have been trying for a while to get a good "Aqua UI" look out of XL6 without much success. Caustics in XL7 help quite a bit. Note the render times are quite reasonable.

Using the XL7 Demo on a 384MB G4/450 with OS9.1. A couple of OSX-y images. No radiosity.

The elusive OSX look, using caustics and the fresnel shader.
Here's the same thing without caustics.

And something more along the lines of a gel cap. This is on a 128MB PII/300 running NT4SP3. Using caustics and the fresnel shader.
