Cage Projection Method

Normal Bump Mapping using cage projection also involves a source and target object.

In this tutorial, you will create a cage object and form it to fit the contours of the target, a low-resolution model of a human head. You will then use the cage to receive the diffuse and normal bump map information from the source, a high-resolution version of the model.
