虚拟地图路线结合实拍视频 Digital Tutors – Using the 3D Camera Tracker and Intergrating Graphics in After Effects运用AE内置的摄像机跟踪3D camera tracker ，然后后期制作的虚拟地图路线结合到视频视频中In this series of tutorials, we’ll learn how to use After Effects’ 3D Camera Tracker and how to integrate assets into the shot.

We’ll be doing an augmented reality style project to learn these techniques.

While the graphics have more of a 2.

5D feel, they are totally integrated into the 3D space of the original shot.

To be able to achieve this look we must learn which settings we need for the 3D camera tracker and then how to use it to create a camera and null objects.

We then learn how we can take simple 2D graphics which are switched on to 3D, to be placed into the scene all while following the depth of the shot.

We learn the value of nested compositions and the role that collapse transformations plays as well as a few techniques for working with and animating strokes in After Effects.

By the end of this tutorial you’ll know how to solve a shot in 3D as well as integrate graphics into the scene.
