Aspects of the present disclosure are directed to a holographic calling system providing holographic calling between an artificial reality device and a mobile device having both front and back facing cameras. The user of the mobile device can position it so one of the cameras is pointed toward their face and another camera captures the user's hand not holing the mobile device. The holographic calling system can automatically determine the position of the mobile device in relation to the user's face and hand. Once the mobile device is positioned within an appropriate capture zone, the captured images of the user's face are used to create a first representation of the sending user's face, the captured images of the user's hand are used to create a second representation of the sending user's hand. Each representation is provided as output from a receiving artificial reality device, positioned relative to each other.

A virtual object system can orchestrate virtual objects defined as a collection of components and with inheritance in an object hierarchy. Virtual object components can include a container, data, a template, and a controller. A container can define the volume the virtual object is authorized to write into. A virtual object's data can specify features such as visual elements, parameters, links to external data, meta-data, etc. The template can define view states of the virtual object and contextual breakpoints for transitioning between them. Each view state can control when and how the virtual object presents data elements. The controller can define logic for the virtual object to respond to input, context, etc. The definition of each object can specify which other object in an object hierarchy that object extends, where extending an object includes inheriting that object's components, which can be modified or overwritten as part of the extension.

Disclosed is a separation method including obtaining a mesh model separated into an object unit, based on a segmentation image extracting an object included in an image sequence, updating second label information of the separated mesh model, based on first label information of the segmentation image and a user's input, and updating the separated mesh model, based on the updated second label information, in which an integrated mesh model before being separated into an object unit is generated from the image sequence.

Method, device and medium are directed to providing a method for generating three-dimension molecules. The method comprises obtaining a molecular shape of a three-dimension molecule for a drug, wherein the molecular shape is represented by a three-dimension image and generating a plurality of fragments of the three-dimension molecule based on the molecular shape. The method further comprises generating the three-dimension molecule by connecting the plurality of fragments. The method may be used to design high quality drugs for specific protein pockets efficiently and speed up the process of drug development and reduce the cycle of drug development. Furthermore, since the method utilizes large-scale non-experimental data, the method may not rely on expensive experimental data and docking simulation which is time consuming. Additionally, the method utilizes the three-dimension interaction information between molecules and pockets to generate drug molecules, and thus the quality of generated drug molecules can be improved.

The scale of modeled building objects from collected imagery is determined by identifying architectural elements within building object imagery, determining a scale of the identified architectural elements by matching them to known industry standard architectural element based on dimensional ratio comparisons and deriving an average scaling factor based on scale of the identified architectural elements. A three dimensional model of the building object is scaled according to the average scaling. Scaled architecture elements within a relative error can be used for scaling the model according to an updated scale factor.
