Patent number: 12229879Abstract: An image rendering method and a related apparatus, terminal and storage medium that: obtains a low-resolution first shadow map and a high-resolution second shadow map of a target virtual object, determines a first texel range of each texel and a central point in the first shadow map, performs scaling processing, based on the central point, on the first texel range by using a scaling coefficient to obtain a second texel range, and performs shadow rendering on the target virtual object according to the second texel range. A shadow map-based image rendering process is implemented, and since a calculation amount of determining a map position according to a low-resolution map is relatively small, image rendering efficiency is improved. Additionally, rendering of a high-resolution shadow map is completed, generation of edge aliasing is avoided, and an image rendering effect is improved.Type: GrantFiled: March 17, 2022Date of Patent: February 18, 2025Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Huabing Xu, Shun Cao, Nan Wei, Xiaochun Cui, Congbing Li, Rongxin Zhou, Wenyan Li

Publication number: 20240331257Abstract: This application describes an animation data generation method and apparatus, and a related product, which may be applied to scenarios such as a cloud technology, artificial intelligence (AI), intelligent transportation, assisted driving, digital human, virtual human, gaming, virtual reality, and extended reality (XR). Features of a virtual object in a virtual scene are obtained, and animation data of the virtual object is generated through a trained neural network based on the features. The use of the neural network omits storage of massive data into an internal memory and query of the massive data for a matched animation during generation of the animation data, and only requires storage of weight data related to the neural network in advance. Therefore, only a small internal memory is occupied, thereby avoiding problems such as large internal memory occupation and poor query performance during generation of the animation data.Type: ApplicationFiled: June 11, 2024Publication date: October 3, 2024Inventors: Shun CAO, Hua KOU, Yifan CAO, Nan WEI, Yu WU, Congbing LI, Xiaochun CUI

Patent number: 11140787Abstract: This document describes techniques and apparatuses for connecting an electronic component to an interactive textile. Loose conductive threads of the interactive textile are collected and organized into a ribbon with a pitch that matches a corresponding pitch of connection points of the electronic component. Next, non-conductive material of the conductive threads of the ribbon are stripped to expose the conductive wires of the conductive threads. After stripping the non-conductive material from the conductive threads of the ribbon, the connection points of the electronic component are bonded to the conductive wires of the ribbon. The conductive threads proximate the ribbon are then sealed using a UV-curable or heat-curable epoxy, and the electronic component and the ribbon are encapsulated to the interactive textile with a water-resistant material, such as plastic or polymer.Type: GrantFiled: September 6, 2019Date of Patent: October 5, 2021Assignee: Google LLCInventors: Mustafa Emre Karagozler, Ivan Poupyrev, Nan-Wei Gong, Karen Elizabeth Robinson, Patricia Hayes-Danitz, Megan Grant

Patent number: 11103015Abstract: This document describes techniques using, and objects embodying, an interactive fabric which is configured to sense user interactions in the form of single or multi-touch-input (e.g., gestures). The interactive fabric may be integrated into a wearable interactive garment (e.g., a jacket, shirt, or pants) that is coupled (e.g., via a wired or wireless connection) to a gesture manager. The gesture manager may be implemented at the interactive garment, or remote from the interactive garment, such as at a computing device that is wirelessly paired with the interactive garment and/or at a remote cloud based service. Generally, the gesture manager recognizes user interactions to the interactive fabric, and in response, triggers various different types of functionality, such as answering a phone call, sending a text message, creating a journal entry, and so forth.Type: GrantFiled: April 8, 2020Date of Patent: August 31, 2021Assignee: Google LLCInventors: Ivan Poupyrev, Carsten C.
