Title: Innovations of Ulrik Lindahl
Introduction
Ulrik Lindahl is a notable inventor based in Linkoping, Sweden. He has made significant contributions to the field of 3D modeling and image processing, holding a total of 5 patents. His work focuses on enhancing the efficiency and quality of 3D objects through innovative techniques.
Latest Patents
One of his latest patents is titled "Complexity reduction of objects via hole filling." This patent discloses systems and methods for removing details from three-dimensional (3D) objects, such as cavities and holes. The complexity reduction via hole filling minimizes storage, transfer, and rendering costs without adversely impacting quality. This process is implemented in an automated manner, where a 3D object is dilated and eroded, and undesirable webbing is removed to preserve a higher percentage of exterior detail. Holes and cavities, which are often obscured from many viewing angles, are filled in, thereby reducing the burden of storing and processing hidden interior surfaces. Various approaches, leveraging distance fields, may be combined for improved benefit.
Another significant patent is "Rendering based generation of occlusion culling models." This patent provides a method and image processing apparatus for creating simplified representations of an existing virtual 3D model for use in occlusion culling. A visual hull construction is performed on the existing virtual 3D model using an approximate voxel volume consisting of a plurality of voxels. A set of projections from multiple viewing angles provides a visual hull of the existing 3D model. The volumetric size of the visual hull is adjusted to create occludee and occluder models, which are utilized during runtime in a 3D virtual environment for occlusion culling.
