The main shape is a quite complex blob work. It is based on a set of points that I generated using random points generation and manipulation macros. After that, I used the points to generate the 3 blob based shapes, the orange which is the soft one inside of the global shape, the blue which is the hard edged outside and the glass one which is actually a difference of two blobs. For all of these I used the same points, with just a variation of the forces and radiuses.
The cutaway was simply done by adding big negative blob spheres that annulate a part of the blobs.
The blue texture was taken from Tek's work on metallic painting. Other textures are quite basic ones I made myself.
The ground is an image mapped height field based on a photo I made.
The lighting is done by an HDRI, I used the Galileo Probe that I found on
Paul Debevec site and that I
used with his authorisation.
Unfortunately I didn't have enough time to render the image with good enough radiosity quality.
