Patent number: 10529132Abstract: Disclosed is a method for real-time cutting of digital organ based on a metaball model and a hybrid driving method, including a cutting procedure for driving a model using a position-based dynamics and a meshless method, a cutting mode which begins from a metaball driven by the position-based dynamics, proceeds to a point set driven by the meshless method and then create a new metaball. The method includes: a preprocessing procedure which performs an initialization operation while reading a model file; a deforming procedure which drives a model using a method based on the position-based dynamics; a cutting procedure which drives the model using the hybrid driving method and performs cutting using said cutting mode; and a rendering procedure which renders the model during the second and third procedures.Type: GrantFiled: December 7, 2017Date of Patent: January 7, 2020Assignee: BEIHANG UNIVERSITYInventors: JunJun Pan, Shizeng Yan, Qinping Zhao

Patent number: 10268774Abstract: Embodiments of the present application relate to a method for displaying a web page, a system for displaying a web page, and a computer program product for displaying a web page. A method for displaying a web page is provided. The method includes pre-processing text information to be picture processed in a web page, creating a picture, generating a position description for each text block in the picture, filling the corresponding text blocks into the picture based on the position descriptions, generating a call address for the picture, and correspondingly saving the call address and the position description of each text block as metadata. If an access request for the web page is received, invoking the metadata, loading the picture, selecting at least one corresponding text block from the picture, and displaying the at least one text block is performed.Type: GrantFiled: April 5, 2017Date of Patent: April 23, 2019Assignee: Alibaba Group Holding LimitedInventors: Junwen Chen, Junjun Pan
