摘要:
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.
摘要:
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.
摘要:
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.

Provided are an adaptive rendering apparatus and method using a hierarchical structure in a 3D image and a computer-readable recording medium storing a computer program for executing the adaptive rendering method. The adaptive rendering apparatus includes a cell data provision unit, which divides an original 3D image into a plurality of lattice cells that are connected to one another in a hierarchical structure according to predetermined rendering conditions and outputs a plurality of cell data of an area of the original 3D image corresponding to the lattice cells, and a rendered image generation unit, which generates a 3D rendered image by arranging the cell data output from the cell data provision unit according to the hierarchical structure. A lattice cell belonging to a particular level in the hierarchical structure is capable of being divided into a plurality of lattice cells belonging to a level directly below the particular level, and each of the lattice cells in the level directly below the particular level is smaller than the lattice cell of the particular level. A lattice cell belonging to a particular level in the hierarchical structure is capable of being divided into 8 smaller lattice cells belonging to a level directly below the particular level. Accordingly, it is possible to adjust the quality of a rendered image and the speed of generating the rendered image and to precisely render both a 3D object image and a 3D scenic image.
