The drawing is designed with Moray 3.5 build 9669. The rendering is made with povray 3.5. Elsa is 7 yars old and she designed the dolphin using bezier patches. She can edit the patch and move the highlighted points to model the form. For the textures it's a bit difficult, so her grand-fther has to help a bit.
Rendering the bottom of the seaz was a big problem. So, after some trials, she choose 2 infinite planes. The lower plane is roteted to obtain an far intersection with the upper one.
For the bubbles, multiple copies where done, and the little spheres where manually moved at the right place.
The rendering takes 1 hour
