摘要： 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 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.
