I had a go at modelling a shark in Cinema 4D, following a video tutorial on kcdigitalarts.net for guidance.
To get the picture in, you have to go to options>configure>then image and bring in the one of your choice.
This was the end result of what I did. I used a cylinder to form the basis of the shark, manipulating the shape to try and match the shape of the image onscreen, along the way I seemed to slip up somewhere. With Practice I am positive that I will create a better looking model!
