In today’s lesson, we’ve been covered about the 3D aspect of Nuke compositing. One of Nuke’s strongest tool is 3D Camera Projection which are very commonly used in

Matchmoving:
The process of matching the camera movement/object movement in 3D space so the software can interpret the shot and match the 3d objects/geometry corresponding to the movement of the real plate.

Lens Distortion
Every lenses have some kind of distortion, and before we can start tracking/matchmove we have to account for this by using LensDistortion node to undistort the image first. This can be done automatically with checkerboard (if provided by production)

However, if no checkerboard was provided then there are ways to solve it manually, by drawing lines which are supposed to be straight then let Nuke solve the distortion (More lines the better Nuke can solve)
