The next thing I wanted to explore in this project was integrating computer graphics and video footage. Following on from my Bete Noir idea from earlier of animating a scribble, I first modelled a 3D scribble by bending a cylinder using the techniques I picked up during starting my name logo.

I was unsure as to what material to assign to it as most that I used looked quite unnatural. In the future I will try and make some textures to use as a base, such as a texture of pencil, and tapering of the cylinder in order to make it look like more like a pencil or pen stroke.

Next was to track the movement of my hand in the video in order for the scribble ball to follow this movement. This proved to be quite challenging as the quality of the video wasn’t that good so using a better quality camera in the future would be a good idea.  I then linked the movement of the camera to the ball so it would move along with the movement of my hand in the 3D space.

I added some extra movement and rotation to the ball so it looked like it actually was in the hand instead of sitting on top of it. Then I rendered the sequence out and layered it on top of the original footage. Unfortunately I messed up during rendering, so the background of the 3D ball sequence was white. As I did not have enough time I was unable to render it again. Fortunately I could lower the opactiy of this layer so the video underneath could still be shown through.

Here’s a link to the final result.

Overall I think it worked alright. The tracking of the movement could have been improved by adding more points. I could have also spent more time on the animation as I was slightly rushing this in order to see the result, with more time it would have looked more effective.

In the future I would also have used a video clip with a bit more motion as that would probably make the animation more impressive. However through doing this I now know some of the basics of motion tracking in Blender, which is a new area for me and one which I would like to explore.
