    摘要： Systems and processes for rendering fractures in an object are provided. In one example, a surface representation of an object may be converted into a volumetric representation of the object. The volumetric representation of the object may be divided into volumetric representations of two or more fragments. The volumetric representations of the two or more fragments may be converted into surface representations of the two or more fragments. Additional information associated with attributes of adjacent fragments may be used to convert the volumetric representations of the two or more fragments into surface representations of the two or more fragments. The surface representations of the two or more fragments may be displayed.

    摘要： The present invention discloses a method for rapidly vectorizing an image by gradient meshes based on parameterization, which comprises the following steps: determining an image region to be vectorized (S1); converting the image region into amesh representation (S2); mapping the meshes to a planar rectangular region by parameterizing the meshes (S3); and generating a gradient mesh image according to the parameterization result of said meshes (S4). The present invention generates gradient meshes by converting an image region into meshesand by parameterization, so the gradient meshes are obtained completely automatically without the need for the user to give original meshesand moreover, the computation speed is improved significantly since nonlinear optimization is avoided. In addition, the method of the present invention can process image regions containing or not containing holes.

    摘要： The invention relates to a method for generating a 3-dimensional representation of a tunnel. The method comprises the step of providing road network data (11) including a plurality of road segments, at least one road segment being a tunnel road segment, including the information that said at least one road segment is a road segment located in a tunnel. Furthermore, the method comprises the steps of identifying said tunnel segment in the road network, providing a geographical elevation map (12) including elevation data of the geographical region in which the tunnel road segment is located, providing predefined patterns (13) representing predefined parts of a 3-dimensional tunnel body, generating the 3-dimensional representation of the tunnel based on the tunnel road segment, the elevation map (12) and the predefined patterns (13), and storing the 3-dimensional representation of the tunnel in connection with the road network as a 3-dimensional object which is located at the geographical position of the tunnel road segment.

    摘要： Architecture that combines multiple depth cameras and multiple projectors to cover a specified space (e.g., a room).The cameras and projectors are calibrated, allowing the development of a multi-dimensional (e.g., 3D) model of the objects in the space, as well as the ability to project graphics in a controlled fashion on the same objects. The architecture incorporates the depth data from all depth cameras, as well as color information, into a unified multi-dimensional model in combination with calibrated projectors. In order to provide visual continuity when transferring objects between different locations in the space, the user's body can provide a canvas on which to project this interaction. As the user moves body parts in the space, without any other object, the body parts can serve as temporary "screens" for "in-transit" data.
