Abstract: A method for supporting 3D printing includes identifying a product, searching and providing a 3D model present on a web in relation to the identified product, calculating and simulating suitability between the identified product and the searched 3D model based on information of the identified product and the searched 3D model, and transmitting the 3D model information to a 3D printer to produce the 3D model. Accordingly, the 3D printing technique may be actively utilized for DIY in various fields, business models or the like.

Abstract: Relating to an the integrated rendering method for various extended reality modes and a device having thereof, loading an XR-scene content including at least one virtual object content representing an extended reality image from a storage and representing a virtual object included in the extended reality image; inputting a selection, from a user, of any one extended reality mode among a plurality of extended reality modes including a virtual reality mode and an augmented reality mode; and maintaining or converting a property of each of a plurality of rendering options for at least one virtual object content according to the selected extended reality mode, and rendering at least one virtual object content having the maintained or converted property. Therefore, a virtual reality image and an augmented reality image can be generate from one XR-scene content.

Abstract: Disclosed is a content management method, which includes obtaining data for a content including a plurality of point-of-interest (POI) and a plurality of POI documents associated with each of the plurality of POIs, obtaining at least one level-of-detail (LOD) information which allows the content to be displayed according to an interest of the user, and determining a display format for the content based on the LOD information. Here, the LOD information may include information for the interest level of the user with regard to the content, and the interest level may be independent from a scale level of a map at which the content is displayed.
