摘要:
A collision sensing apparatus, method and medium are provided. The apparatus includes an image dividing unit to divide an image into a plurality of voxels, a searching unit to search for a voxel having a plurality of model primitives, among the plurality of voxels, and an examination unit to determine whether a collision occurs between two or more model primitives in the searched voxel.

A 3D graphics processing method includes receiving a homogeneous coordinate and an attribute value of both end points of one scan line of a polygon composed of a plurality of perspective projected vertices, calculating a reference value indicating an amount of perspective distortion in the scan line using the received homogeneous coordinates, and interpolating an attribute value of each of pixels of the scan line using at least some of the received homogeneous coordinates and attribute values, the attribute value interpolated by selectively applying perspective correction to each pixel based on the reference value.
摘要:
A method, medium, and system authoring 3D (three-dimensional) graphic data. In the method, a rendering function corresponding to characteristics of an authored object is generated. It is determined whether the total number of rendering functions including the generated rendering function exceeds a predetermined number. The object is re-authored to correspond to one of the total number of rendering functions according to results of the determining. When 3D graphic data is reproduced, the number of rendering functions being used can be limited, and thus, a reduction in rendering performance during the authoring phase can be prevented.
摘要:
A 3D graphics processing method, medium and apparatus performing perspective correction is described. The 3D graphics processing method includes receiving a homogeneous coordinate and an attribute value of both end points of one scan line of a polygon composed of a plurality of perspective projected vertices, calculating a reference value indicating an amount of perspective distortion in the scan line using the received homogeneous coordinates, and interpolating an attribute value of each of pixels of the scan line using at least some of the received homogeneous coordinates and attribute values, the attribute value interpolated by selectively applying perspective correction to each pixel based on the reference value. Accordingly, processing time and power consumption may be reduced.
摘要:
A system, method and medium for processing objects including 3D graphic data, wherein the processing time for converting 3D graphic data into a 2D image can be minimized by aligning and converting the objects of the 3D graphic data into the 2D image based on the appearance information corresponding to the effects information or shader code.
