In the third weeks’ Nuke class, I have learned about 3D camera tracking. It is quite different from a 2D tracker, in 3D tracking, the camera will be set as the same camera which be filmed in the original video so that the view in Nuke will look the same after tracking.

I have used 3D tracking in After Effect, but after studying Nuke’s 3D tracking, the difference is Nuke’s 3D tracking will be more precise and controllable. In the After Effect, the environment will be tracked automatically by 3D tracking, we can not control amounts of tracking points and we also cannot use some specific camera setting. So for some complex or more specific points which need to be tracked, Nuke’s 3D track will be better than After Effect for sure.

For this week’s 3D tracking homework, we will track our own Crypt project. To track this video, I have set 1000 tracking points just in case there will be some issues with these points, and also I can clearly to see the environment through these points. After I set the camera’s setting values, I start to 3D track and solve my points. After that, I have created three cards in the scene and changed them to be my wireframe.

The problem I got during tracking my scene is tracking points, in the viewer of my tracking points, the ground is not flat and has some inclination, I’m not sure it is my tracking issue or my camera setting, and also, when I create a card node, it’s a bit hard to control and rotate it, so I’m still finding a good way to do it.
