  • Publication number: 20240004542
    Abstract: Some examples provides a set of frameworks, process and methods aimed at enabling the expression and exploration of free-form and parametric 3D shape designs enabled through natural interactions with a hand-held mobile device acting as a controller for 3D virtual objects. A reference plane in a virtual space generated by the location of the mobile device may be used to select a 3D virtual object intersected by the reference plane. Positioning of the mobile device may also be used to control a pointer in the virtual space. In an example, the orientation of the mobile device may be detected by an accelerometer or gyroscope. In example, the position of the mobile device may be detected by a position sensor.

  • Publication number: 20230011393
    Abstract: A method for creating a space-filling solid model includes (a) defining a three-dimensional (3D) domain, (b) defining a Voronoi site geometry for each of a plurality of Voronoi sites, (c) defining a spatial arrangement of the plurality of Voronoi sites, (d) arranging the plurality of Voronoi sites within the 3D domain according to the defined spatial arrangement, and (e) partitioning the 3D domain based on the Voronoi site geometry of each the plurality of Voronoi sites defined in (b) and the spatial arrangement of the plurality of Voronoi sites defined in (c) using a distance function to create the space-filling solid model.

  • Patent number: 11543933
    Abstract: A method of manipulating a three-dimensional image file including a virtual object includes obtaining image information in a processing device of a non-instrumented physical object manipulated by a user, such image information including movement information; and causing virtual movement of the virtual object based on the movement information. A method of shaping a virtual object includes obtaining image information including movement information; and determining a shape of the virtual object based on the movement information. A method of modifying a virtual object includes obtaining image information including movement information; and altering a virtual surface appearance of at least a part of the virtual object based on the movement information. Systems and computer-readable media are also described.

  • Patent number: 11475651
    Abstract: A virtual reality system, comprising an electronic 2d interface having a depth sensor, the depth sensor allowing a user to provide input to the system to instruct the system to create a virtual 3D object in a real-world environment. The virtual 3D object is created with reference to at least one external physical object in the real-world environment, with the external physical object concurrently displayed with the virtual 3D object by the interface. The virtual 3D object is based on physical artifacts of the external physical object.
