The present invention relates to a device and a method for simulating 3D printing and more particularly, to a simulation technology which is able for a producer or a user to predict and correct a 3D model through previews shown when the 3D model displayed in a monitor is outputted by a 3D printer.

Device and method for simulating 3D printing

An apparatus for 3D mesh compression based on quantization, includes a data analyzing unit () for decomposing data of an input 3D mesh model into vertices information () property information () representing property of the 3D mesh model, and connectivity information () between vertices constituting the 3D mesh model: and a mesh model quantizing unit () for producing quantized vertices and property information of the 3D mesh model by using the vertices, property and connectivity information (). Further, the apparatus for 3D mesh compression based on quantization includes a decision bit encoding unit () for calculating a decision bit by using the quantized connectivity information and then encoding the quantized vertex information, property information and connectivity information () by using the decision bit.

An apparatus for transforming an image in a mobile device is disclosed. The apparatus comprises a pen style transformation unit for transforming an original image to a pen style image using a separated Gaussian filter and outputting pen style image, a cartoon style transformation unit for transforming the original image to a cartoon style image and outputting the cartoon style image, a mosaic creation unit for creating a photomosaic to which the original image is applied based on an optimum photo image set and outputting the created photo mosaic by applying the created photo mosaic to the original image, and an image output unit for outputting the images output from the pen style transformation unit, the cartoon style transformation unit, and the mosaic creation unit to an output unit.

An apparatus for producing digital cartoons includes: an image collection unit for collecting photorealistic image data; and a cartooning processor for performing a rendering process including image abstraction and edge generation on the photorealistic image data collected by the image collection unit to generate cartooned images. The apparatus further includes a stylization unit for producing a cartoon page having various shapes of cartoon frames, resizing the cartooned images to place the resized images into the cartoon frames and adding cartoon elements to the images placed in the cartoon frames.

Method and apparatus for producing digital cartoons

An apparatus for processing an effect using style lines, includes a contour line creation unit for creating contour lines using polygons of a three-dimensional (3D) object and location information of a camera; a style line creation unit for putting edge lists, extracted at the time of creating the contour lines, into groups, and creating one or more style lines for each of the groups; and an effect processing unit for representing a line style by inserting the created style lines inside and outside a contour line corresponding to the group. Therefore, representation to appear to have been drawn by a human hand is enabled by adding style lines to existing contour lines in order to represent a line style that belongs to various styles of non-photo realistic rendering.

Apparatus for proccessing drawn-by-human-hand effect using style lines

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.
