Abstract: A three-dimensional (3D) rendering method and apparatus to render a 3D scene is disclosed. The 3D rendering apparatus determines color values of vertices shaded by a direct virtual light source, establishes one or more locations of one or more indirect virtual light sources in polygonal areas formed by the vertices based on the determined color values of the vertices, and renders a 3D scene based on the one or more indirect virtual light sources disposed at the determined one or more locations.

Abstract: A method and corresponding apparatus to model objects includes detecting an overlapping area between first and second objects each comprising particles. The method and corresponding apparatus also calculate, in the overlapping area, an action force between the first and the second objects. The method and corresponding apparatus model the first object and the second object based on the action force.

Abstract: A three-dimensional (3D) rendering method and apparatus is disclosed. The 3D rendering apparatus may determine a select shading point in a 3D scene on which shading is to be performed, perform the shading on the determined shading point, and determine shading information of the 3D scene based on a result of the shading performed on the determined shading point.

Abstract: A three-dimensional (3D) rendering method and apparatus is disclosed. The 3D rendering apparatus determines a vertex for a first shading from among vertices of a 3D model based on characteristic information of the 3D model, performs the first shading on the determined vertex, determines a pixel area for a second shading based on reference information indicating whether the first shading is applied to at least one vertex comprising the pixel area, performs the second shading on the determined pixel area, and generates a rendered image based on the first shading and the second shading.

Abstract: Provided is a method and apparatus for rendering a target fluid that include defining level-set information of fluid particles configuring a modeled target fluid. The level-set information comprises a shortest distance from a surface of the target fluid to the fluid particles. The method and apparatus are include discarding internal particles of the target fluid from the modeled target fluid based on the level-set information of the fluid particles, and calculating thickness information of the target fluid, from which the internal particles are discarded, based on depth information on the fluid particles. The target fluid is rendered based on the thickness information of the target fluid.
