Device and method for generating dynamic virtual contents in mixed reality

A method of generating at least one dynamic virtual content to be superimposed to a representation of a real 3D scene, said at least one dynamic virtual content complying with at least one scenario defined before a runtime of said at least one scenario and involving at least one real-world constraint, said method comprising:

• receiving real-world information captured in said real 3D scene;
• and
• executing said at least one scenario at said runtime in presence of said at least one real-world constraint identified from said real-world information,
• wherein said method further comprises, when said at least one real-world constraint is not identified from said real-world information, carrying out before executing said at least one scenario a transformation of said representation of said real 3D scene to a virtually adapted 3D scene so that said virtually adapted 3D scene fulfills said at least one constraint, and instead of executing said at least one scenario in said real 3D scene, executing said at least one scenario in said virtually adapted 3D scene replacing said real 3D scene.

An apparatus configured to generate at least one dynamic virtual content to be superimposed to a representation of a real 3D scene, said at least one dynamic virtual content complying with at least one scenario defined before a runtime of said at least one scenario and involving at least one real-world constraint, said apparatus comprising:

• a processor;
• and
• a non-transitory computer-readable medium storing instructions, the instructions operative, when executed by the processor, to cause the apparatus to:
• receive real-world information captured in said real 3D scene;
• and
• execute said at least one scenario at said runtime in presence of said at least one real-world constraint identified from said real-world information,
• wherein the instructions are further operative, when executed by the processor and when said at least one real-world constraint is not identified from said real-world information, to cause the apparatus to carry out before executing said at least one scenario a transformation of said representation of said real 3D scene to a virtually adapted 3D scene so that said virtually adapted 3D scene fulfills said at least one constraint, and instead of executing said at least one scenario in said real 3D scene, execute said at least one scenario in said virtually adapted 3D scene replacing said real 3D scene.
