What is the function of the Puppet Warp tool?

The Puppet Warp tool is designed to provide fine control over the distortion of specific parts of an image while maintaining the overall integrity of the rest of the layer. By placing pins on the areas you want to manipulate, you can move, rotate, or warp those specific sections without affecting other parts of the image. This feature is particularly useful for editing photographs or compositions where you want to make subtle adjustments, such as repositioning limbs in a portrait or altering the shape of an object, all while keeping the surrounding area intact.

In contrast, blending images seamlessly involves different techniques, such as layer masks or blending modes, which are not the focus of the Puppet Warp tool. Creating 3D models from 2D images and applying global transformations apply to broader alterations that affect the entire layer or represent a different set of functionalities that do not align with the specific capabilities of Puppet Warp.
