Abstract
A device for immersing a user in an immersive scene is described. The device sends, to a device for processing 3D objects, a request comprising a position and an orientation of an eye of an avatar of the user in the immersive scene and display parameters for displaying a 3D object in the scene. The device for processing 3D objects determines a two-dimensional image representing a point of view of the eye of the avatar on the 3D object and a position of this image in the scene. This two-dimensional image is displayed in the immersive scene in order to represent the object.
Claims12
A method for immersing a user in an immersive scene, the method implemented by an immersion device, the method comprising:
- sending, to a device for processing three-dimensional objects, a request including a position and an orientation of an eye of an avatar of the user in the immersive scene and display parameters for an object modeled in three dimensions in said scene, the position and orientation of the eye of the avatar being those of an eye of the user or those of a fictitious point placed between two eyes of the user, the display parameters for the complex object including an identifier, a position, an orientation and a size of the complex object in a reference frame of the immersive scene;
- receiving a two-dimensional image and a position of said image in said scene calculated by said device for processing three-dimensional objects, said image representing a point of view of the eye of the avatar on said object;
- and
- displaying said two-dimensional image in the immersive scene at said position and by taking into account said orientation of the eye of the avatar.
A method for processing at least one object modeled in three dimensions, the method comprising:
- receiving, from a device for immersing a user in an immersive scene, a request including a position and an orientation of an eye of an avatar of a user in said immersive scene and display parameters for said object in said scene two eyes of the user, the display parameters for the complex object including an identifier, a position, an orientation and a size of the complex object in a reference frame of the immersive scene;
- determining a two-dimensional image and a position of said image in said scene, said image representing a point of view of the eye of the avatar on said object;
- and
- sending said two-dimensional image and said position of said image in the immersive scene to said immersion device.
A device for immersing a user in an immersive scene, the device configured to:
- send, to a device for processing three-dimensional objects, a request including a position and an orientation of an eye of an avatar of the user in the immersive scene and display parameters for an object modeled in three dimensions in said scene, the position and orientation of the eye of the avatar being those of an eye of the user or those of a fictitious point placed between two eyes of the user, the display parameters for the complex object including an identifier, a position, an orientation and a size of the complex object in a reference frame of the immersive scene;
- receive a two-dimensional image and a position of said image in said scene, calculated by said device for processing three-dimensional objects, said image representing a point of view of the eye of the avatar on said object;
- and
- display said two-dimensional image in the immersive scene at said position and by taking into account said orientation of the eye of the avatar.
A device for processing objects, the device configured to process at least one object modeled in three dimensions, the device configured to:
- receive, from a device for immersing a user in an immersive scene, a request (RQ) including a position and an orientation of an eye of an avatar of a user in said immersive scene and display parameters for said object (OC) in said scene (SI), the position and orientation of the eye of the avatar being those of an eye of the user or those of a fictitious point placed between two eyes of the user, the display parameters for the complex object including an identifier, a position, an orientation and a size of the complex object in a reference frame of the immersive scene;
- determine a two-dimensional image and a position of said image in said scene, said image representing a point of view of the eye of the avatar on said object;
- and
- send said two-dimensional image and said position of said image in the immersive scene to said immersion device.
