摘要： 3D mesh models are widely used in various applications for representing 3D objects. These models are made of vertices and corresponding triangles, which can be compressed based on prediction and residuals. The present invention improves the accuracy of parallelogram prediction, particularly near sharp features. The proposed 3D mesh model encoding comprises analyzing the spatial or dihedral angles between triangles, clustering triangles with similar or equal dihedral angles, and defining a representative dihedral angle for each cluster. Triangles of each cluster are then encoded relative to individual prediction triangles having the representative dihedral angle according to the cluster. Additionally, the prediction triangle may be mirrored. An indication of the encoding mode is inserted into each vertex of the encoded bitstream. A decoder extracts the encoding mode indication, reconstructs the individual prediction triangles based on the respective representative dihedral angles and performs triangle prediction and reconstruction.

摘要： 3D mesh models are represented by three types of data: connectivity data, geometry data and property data. The surface of a 3D object is a triangle mesh. 3D meshes contain huge amounts of data that need to be compressed efficiently. Additionally to the common world coordinate system (WCS) for the complete model and local coordinate system (LCS) for a single triangle, an individual component coordinate system (CCS) for each connected component is used. The component coordinate system (CCS) is used to normalize (53) the orientation of the respective component for quantization and de- quantization. This improves the accuracy of encoded 3D mesh models after quantization/de-quantization, particularly if a 3D mesh model comprises one or more distinct components.

摘要： The invention is made in the technical field of encoding and decoding of bit sequences. The invention proposes a device for compression-encoding an input bit sequence (IBS) in which Zeroes and Ones occur equally frequent, comprising an XOR gate (XOR) adapted for receiving pairs of immediately succeeding bits of the input bit sequence (IBS) as inputs and for outputting further bits of an other bit sequence (OBS), means for adding a bit to said other bit sequence (OBS) wherein the added bit is a primary bit which is equal to a primary bit of the input bit sequence (IBS) or a last bit which is equal to a last bit of the input bit sequence (IBS), and means for encoding the other sequence. The XOR gate (XOR) transforms the input bit sequence (IBS) into the other bit sequence (OBS) which comprises more uneven frequencies of occurrence of Zeroes and Ones than the input bit sequence (IBS).

摘要： 3D models often have a large number of small to medium sized connected components, with small numbers of large triangles, often with arbitrary connectivity. The efficiency of compact representation of large multi-component 3D models can be improved by detecting and representing similarities between components thereof, even if the components are not exactly equal. The invention uses displacement maps for encoding two or more different but similar geometry patterns differentially, based on clustering and a cluster representative surface (CRS). A method for encoding a plurality of geometry patterns comprises detecting and encoding identical copies of geometrical patterns (100), detecting and clustering similar geometry patterns (200), and detecting partial similarity (300). The detecting partial similarity (300) comprises generating a cluster representative surface, generating for at least one clustered geometry pattern a displacement map, and encoding the common surface and the displacement maps.

摘要： A method and a system for crowd simulation are described. Interactions between the agents in a crowd and the terrain the crowd passes through are taken into account in the present invention for simulation. Agent attributes and terrain attributes are employed to define the reaction of the agent to the terrain and to other neighboring agents, and the reaction of the terrain to the agent, respectively. Steering forces incorporating the agent and terrain attributes are calculated and applied to the corresponding agent. The position change for each agent is thus the combined results of the interaction among the agent, its neighboring agents and the terrain underfoot.
