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.

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.

Disclosed are an apparatus and a method of producing a 3D model in which a 3D model having a static background is produced using a point cloud and an image obtained through 3D scanning. The apparatus includes an image matching unit for producing a matched image by matching a point cloud obtained by scanning a predetermined region to a camera image obtained by photographing the predetermined region; a mesh model processing unit for producing an object positioned in the region as a mesh model; and a 3D model processing unit for producing a 3D model for the object by reflecting texture information obtained from the matched image to the mesh model. The disclosed may be used for a 3D map service.

Provided is a graphics processing apparatus. The graphics processing apparatus minimizes the change of the pipeline structure of the existing graphics processing apparatus, enabling compatibility with the existing API. Simultaneously, by calculating the brightness value or color value of the face of an object according to a global illumination scheme, the graphics processing apparatus can provide realistic image videos. Moreover, the graphics processing apparatus generates an image video based on a local illumination scheme through the existing GPU and simultaneously provides a global illumination effect only for a desired region, thereby improving the entire processing speed of a system.
