This week we continued to do some 3D tracking. We learned 3 different ways to track, which are Cameratracker, Pointcloud and ModelBuilder.
Pointcloud:
Create a Pointcloud, and then analyse sequences. Clouds may show like this:
ModelBuilder:
Firstly use the shape tool to create a card, and then adjust the shape and duplicate the edges of the shape, which may finally show like this:
After that, we used Rotopaint to do the clean up. I erased the window. Remember to use the FrameHold to make sure all the frames are covered.
We also had a deep understanding of the difference between two cameras. It was a little bit hard to understand, but if we compare these cameras with the cameras in Maya, it became easier to understand.
Finally, we had a little practice on the Project roto.
