Abstract

This application relates to a method for recommending a cold start object performed by a computer device. The method includes: obtaining a content feature and an initial preference feature that are of a target object in a cold start state; performing multilayer perceptron processing on the content feature based on a meta-mapping network to obtain a feature mapping relationship matching the target object; performing a mapping transformation on the initial preference feature according to the feature mapping relationship, to obtain an updated preference feature close to a target preference feature spatial distribution; and performing recommendation analysis on the target object based on the updated preference feature, to obtain a recommendation result for the target object.

Abstract

This application provides an image rendering method and apparatus, an electronic device, a computer-readable storage medium, and a computer program product. The method comprises the following steps: acquiring texture data of a virtual object; performing differential fitting processing on the texture data to obtain fitted texture data; baking the fitted texture data into a texture image to obtain a rendered texture image; and performing, based on the rendered texture image, image rendering processing corresponding to the virtual.

Abstract

This application provides a method for playing a performance of a virtual object in a virtual scenario performed by an electronic device. The method includes: displaying a virtual object outfitted with a first performance costume in the virtual scenario; in response to a user operation for the virtual object, playing a first part of background audio and displaying a first performance action performed by the virtual object outfitted with the first performance costume corresponding to the first part of the background audio; and automatically replacing the first performance costume outfitted for the virtual object with a second performance costume outfitted for the virtual object in response to the background audio changing from the first part to a second part corresponding to the second performance costume.

Abstract

Various image processing features are described. An interpolated pixel block of a first image may be used to generate a second image. Several types of interpolation may be available for obtaining the interpolated pixel block, and a particular type of interpolation may be determined based on various conditions, such as whether an interpolation feature of a first pixel block in the first image satisfies a feature determination condition. Different interpolation may be performed on the first pixel block according to complexity of image content in the first pixel block, which effectively reduces the computational complexity of up-sampling, avoids the computational resource waste caused by high computational resource consumption interpolation in the case of simple image content, and further reduces computational complexity.

Abstract

In a sub-application running method, page data of a target sub-application is obtained in response to an instruction to run the target sub-application on a target operating system. A runtime environment of the target sub-application is based on a parent application. The page data of the target sub-application is rendered via a browser to obtain a display page of the target sub-application, the browser being executed in the target operating system. The display page of the target sub-application is displayed based on the browser.

Abstract

Embodiments of this disclosure describe a method and an apparatus for controlling a virtual object to interact with a projectile. The method includes: determining a shooting direction of a camera of the virtual scene as a throwing direction of a projectile controlled by the virtual object; determining a motion trajectory of the projectile according to an initial position, the throwing direction, an initial throwing speed of the projectile, and a motion law of an object under an influence of gravity acceleration, so that the motion trajectory conforms to the motion law; displaying, in the virtual scene, the motion trajectory; adjusting the shooting direction of the camera of the virtual scene, to obtain an adjusted throwing direction of the projectile; updating the motion trajectory of the projectile based on the adjusted throwing projectile; and displaying, in the virtual scene, an updated motion trajectory.
