Here is the final submit for the Rolling ball. I was never able to completely incorporate the double shadows but the latest video shows the improvements that were made. Throughout the course I have learned a great deal about compositing and integration. I made many, many mistakes along the way and learned from them. For this project it was forgetting to do a complete mask of the shadows. I did the best I could in Photoshop to recreate one but just couldent get close.
One of the more difficult challenges was simulating the shadow from the fence over the ball. This was accomplished through a camera projection that was re-projected onto the the ball.
