Insérer des objets 3D dans des photos

Wow, cela nécessite un peu de travail cad

  • définir les volumes, perspectives du lieu
  • la/les sources de lumière
  • les réflexions,
  • la modification des ombres projetées
  • ...

et hop, il vous intègre un moteur de rendu 3D avec ombre éclairages, mouvements, collisions ... ben WOW.

Abstract: We propose a method to realistically insert synthetic objects into existing photographs without requiring access to the scene or any additional scene measurements. With a single image and a small amount of annotation, our method creates a physical model of the scene that is suitable for realistically rendering synthetic objects with diffuse, specular, and even glowing materials while accounting for lighting interactions between the objects and the scene. We demonstrate in a user study that synthetic images produced by our method are confusable with real scenes, even for people who believe they are good at telling the difference. Further, our study shows that our method is competitive with other insertion methods while requiring less scene information. We also collected new illumination and reflectance datasets; renderings produced by our system compare well to ground truth. Our system has applications in the movie and gaming industry, as well as home decorating and user content creation, among others.
