Title: Hsueh-Ti Derek Liu: Innovator in 3D Animation and Object Retrieval

Introduction

Hsueh-Ti Derek Liu is a prominent inventor based in Vancouver, Canada. He has made significant contributions to the fields of 3D animation and object retrieval, holding a total of 3 patents. His work focuses on enhancing the animation of three-dimensional avatar heads and improving the search and retrieval of 3D virtual objects.

Latest Patents

One of Liu's latest patents is titled "Mesh retopology for improved animation of three-dimensional avatar heads." This invention relates to methods, systems, and computer-readable media that provide mesh retopology for enhanced animation. The system processes a three-dimensional mesh representing an avatar head, defines local coordinate frames, and utilizes a machine learning model to predict frame fields based on geometric features. It blends these predicted frame fields to calculate unified directional constraints for each mesh face element and applies quad meshing techniques to extract a quad mesh representation of the avatar head.

Another notable patent is "Searching for and retrieving three-dimensional (3D) virtual objects." This invention involves methods and systems to search for and retrieve 3D objects based on user queries. The method includes receiving a query for 3D objects, identifying constraints from the query, generating a second query with descriptors, and performing a search in a data repository containing 3D content. The results are then outputted in response to the initial query.
