摘要： A method for rendering point cloud using a voxel grid, includes generating bounding box including all the point cloud and dividing the generated bounding box into voxels to make the voxel grid; and allocating at least one texture plane to each of the voxels of the voxel grid. Further, the method includes orthogonally projecting points within the voxel to the allocated texture planes to generate texture images; and rendering each voxel of the voxel grid by selecting one of the texture planes within the voxel by using central position of the voxel and the 3D camera position and rendering using the texture images corresponding to the selected texture plane.

摘要： A method for producing cartoon animation using character animation and mesh deformation is provided. The system includes a motion analysis module, a mesh deformation module, a motion deformation module, and a skinning module. The motion analysis module receives existing motion data having information about non-deformed motions of a character, and extracts parameters from the existing motion data by analyzing an animation value that a character's each joint has. The mesh deformation module receives existing mesh data having information about an external appearance of a character and existing skinning data having information for cohering the parameters or bones with mesh, and generates deformed mesh data. The motion deformation module receives the existing motion data and deforms motion using the parameters. The skinning module receives the deformed mesh data, the deformed motion data, and the existing skinning data and generates character animation data having cartoon like motion.

摘要： Provided is a silhouette rendering apparatus and method using temporal coherence in a 3D space. The silhouette rendering apparatus includes: an edge extracting module for extracting edges of a 3D object by using a smooth surface method generating edges on a surface among silhouette extracting algorithms among mesh information representing a mesh shape; a stroke generating module for generating a stroke by linking the acquired edges; and a parameter computing module for determining a related stroke based on camera and object animation information extracted from current and previous frames of the stroke, computing style-related parameters of the stroke, and setting them up. This makes artists freely express silhouette by applying parameters of silhouette edges to a silhouette style having temporal coherence between frames based on a concept that the silhouette edges move in a 3D space. Also, the present invention resolves a problem of temporal coherence of a silhouette rendering style which effectively reflects the shape of a 3D object.
