Creating Texture-Mapped Surface

Automatic Back-projection is mainly for creating texture-mapped surfaces. Photo4D provides a method that can map an untagged image to a Patch or Grid object. The basic idea is as follows:

1. Photograph the object without any tags to provide a good texture image.
2. Load the texture image into Photo4D and compute its camera parameters.
3. Use the computed camera parameters to project points into this texture image. The projected mark will provide texture coordinates for texture mapping.
4. Create object using the texture image.
