Abstract: A filtering system, medium, and method, including determining whether a size of a splat exceeds a predetermined size, smoothing a boundary of the splat if it is determined that the size of the splat exceeds the predetermined size, and sharpening the boundary of the splat if it is determined that the size of the splat does not exceed the predetermined size.

Abstract: A point-based rendering apparatus, method and medium. The point-based rendering apparatus includes a projector to project a point model and to generate a plurality of rendered points, a radius calculator to calculate a radius, corresponding to a predetermined resolution of each of the rendered points, and a splat generator to generate at least one of a hemi-spherical and a spherical splat having the radius of each of the rendered points.

Abstract: A method and apparatus for rendering 3D graphic data is provided. The 3D graphic data is projected onto a 2D screen and points are interpolated and rendered, thereby quickly processing the 3D graphic data.

Abstract: A 3-dimensional (3D) point-based modeling system, medium, and method, with system generating scene information by using point information in relation to a 3D polygon object and position, rotation, and size information of a 3D polygon object in a scene such that the modeling speed of a 3D image can be enhanced, the entire scene being effectively managed, and the resolution in relation to each object can being adjusted conveniently.

Abstract: An apparatus for and method of producing graphics contents and a computer-readable recording medium storing a computer program for executing the method are provided. The apparatus produces graphics contents using a query item, which is a query object indicating graphics contents that a user desires to produce. The apparatus includes: a model database storing a plurality of models that can match a predetermined query item and shape descriptors of the models; a model-retrieving unit comparing a shape descriptor extracted from a given query item with the shape descriptors of the models stored in the model database and outputting one or more models within a predetermined degree of similarity for user selection; and a model-refining unit refining the selected model according to an instruction from the user and generating a user-intended model. Therefore, three-dimensional graphics contents can be produced quickly and accurately.
