Projection Man

As you already know, Camera Mapping is one of the most important projection types. With Camera Mapping, materials are projected onto objects from the angle of view of the camera. Since each subsequent modification to the camera can result in the material shifting on the object, the cameras are used for purposes other than intended. This is why at least one additional camera is required in the scene for creating fly-by animations or rendering the scene from a different angle.

There are basically two techniques with which Camera Mapping can be completed. You can either use an image as a template to re-create its motif, including its perspective, or you can create a rough model of the scene and subsequently project an image onto it. Projection Man is especially well-suited for the latter method. The Projection Man dialog window can be opened by selecting Projection Man from Cinema 4D’s Window menu. The basic procedure for using Projection Man is described below (a detailed workflow description, including an example, can be found in the Projection Man quickstart manual):

Only objects and their respective surfaces that are seen by the camera will be textured. Hence, additional cameras may be required when mapping more complex scenes. Furthermore, distortions typical of Flat projections will be magnified if the position of the camera used for rendering differs too much from the position of the camera used for projection. Generally speaking, this type of projection is better-suited for use with objects that lie somewhat farther away from the camera used for rendering, e.g., a textured skyline. When using high-res textures, the detail on the objects onto which they are projected can be reduces accordingly.
