Title: Innovations of Hong-Qian Lu
Introduction
Hong-Qian Lu is a notable inventor based in Austin, TX (US). He has made significant contributions to the field of geometry modeling, holding a total of 4 patents. His work focuses on enhancing the visualization and management of geometric models through innovative techniques.
Latest Patents
Among his latest patents is the "Distributed Multiresolution Geometry Modeling System and Method." This patent describes a distributed modeling system that utilizes a database management system on a first server. The system provides access to a hierarchical tree representation of surfaces of geometric models. Client programs connected to the server can access and update the model by traversing this hierarchical tree until a terminating criterion is met. During this traversal, client programs request quad-tree nodes from the database management system.
Another significant patent is "Scalable Visualization for Interactive Geometry Modeling." This invention outlines a method, computer system, and article of manufacture for visualizing a model that includes a first surface. The method determines the rendering resolution of a portion of the first surface based on the view frustum from which it is viewed. It employs techniques such as view frustum culling and bounding sphere projection to select the vertices and edges to be rendered. The method allows for adaptive visualization of geological data in a geoscience model by modifying the visualization of a geometry object according to the view frustum.
