The described implementations relate to complementary augmented reality. One implementation is manifest as a system including a projector that can project a base image from an ancillary viewpoint into an environment. The system also includes a camera that can provide spatial mapping data for the environment and a display device that can display a complementary three-dimensional (3D) image to a user in the environment. In this example, the system can generate the complementary 3D image based on the spatial mapping data and the base image so that the complementary 3D image augments the base image and is dependent on a perspective of the user. The system can also update the complementary 3D image as the perspective of the user in the environment changes.
