Abstract: Systems and methods are disclosed for removing details from three dimensional (3D) objects, such as cavities and holes. Complexity reduction via hole filling reduces storage, transfer, and rendering costs without adversely impacting quality and is implemented in an automated manner. In some examples, 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 obscured in many viewing angles, are filled in (e.g., removed), thereby reducing the burden of storing and processing hidden interior surfaces. Various approaches, leveraging distance fields, may be combined for improved benefit.

Abstract: A method and image processing apparatus for creating simplified representations of an existing virtual 3D model for use in occlusion culling is provided. 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 a plurality of viewing angles provide a visual hull of the existing 3D model. The volumetric size of the visual hull of the existing 3D model is increased to envelop the existing virtual 3D model to provide the visual hull as an occludee model, and the volumetric size of the visual hull of the existing 3D model is decreased to be enveloped by the existing virtual 3D model to provide the visual hull as an occluder model. The occludee model and the occluder model are used during runtime in a 3D virtual environment for occlusion culling.

Abstract: Systems and methods are disclosed for removing details from three dimensional (3D) objects, such as cavities and holes. Complexity reduction via cavity removal reduces storage, transfer, and rendering costs without adversely impacting quality and is implemented in an automated manner. In some examples, distance fields internal and external to the 3D object are removed in a layered manner, and new object surfaces are added wherever openings are narrower than the cavity's internal dimensions, to seal off the cavities. Holes and cavities, which are obscured in many viewing angles, are thus filled in (e.g., removed), thereby reducing the burden of storing and processing hidden interior surfaces. Various approaches, leveraging distance fields, may be combined for improved benefit.

Abstract: A method and system for converting an existing 3D model into graphical data suitable for use with at least one of a plurality of computer systems. The 3D model is stored on a storage server, a pre-processing unit creates a set of individually optimized simplified meshes, each simplified meshes having a degree of simplification and a mapping structure. A user is allowed to interact with a visualization of the 3D model in a graphical user interface to provide the 3D model with selected surface properties, and to select a target computer system from the plurality of computer systems and a degree of simplification. The graphical data is created based on the selected surface properties and an appropriate simplified mesh in the set of simplified meshes, and a preview of the graphical data is shown on the graphical user interface as it would appear on the target computer system. The invention provides an efficient work flow and a quick preview of the graphical data.

Abstract: Panel for covering a recess that accommodates an airbag, which panel comprises an outer foil having at least one foil layer and having an outermost foil layer and a rupture layer having a greater stiffness than the outermost foil layer of the outer foil. The rupture layer is attached to one surface of a foil layer, whereby said rupture layer is provided with at least one break line that is confined to said rupture layer and is arranged to rupture along said at least one break line on inflation of an airbag and to form an opening through the panel for deployment of the inflated airbag.

Abstract: A connector for establishing connection between pipes has an end portion of a maximum diameter which permits insertion of the connector in the pipe, and close to its end an anchoring portion of smaller diameter than the maximum diameter, an arched portion between the anchoring portion and the end, and a connecting portion which extends from the anchoring portion on the side thereof facing away from the pipe end obliquely upwardly to the maximum diameter of the connector. A lip seal of U-shaped cross-section is clamped about the anchoring portion to seal between the outer side of the connector and the inner side of the pipe.
