Abstract

본 발명은 랜더링 방법 및 그 장치에 관한 것으로, 랜더링 할 물체의 데이타를 입력하는 단계(31); 입력된 데이타의 상세도(LOD)를 기준치와 비교하는 단계(32) , 상기 비교결과 기준치를 초과하면, 물체를 구성하는 면의 법선을 산출하는 단계(33); 산술된 법선방향으로 색의 그라데이션(gradation)을 수행하는 단계(34) 및 상기 그라데이션 된 물체의 선과 에지를 엔티에일리에이징하는 단계(35)로 구성되어 상세도가 기준치 보다 클 경우에는 색상의 그라데이션을 수행한 후 엔지에서 엔티에일리에이징을 수행하므로써 랜더링을 위한 계산량을 줄여 처리속도를 향상시킬 수 있다.The present invention relates to a rendering method and an apparatus thereof, comprising: inputting data (31) of an object to be rendered; Comparing the detailed information (LOD) of the input data with a reference value (32), and calculating a normal of the surface constituting the object when the comparison result exceeds the reference value (33); Performing a gradation of the color in the arithmetic normal direction (34) and anti-aging the lines and edges of the gradated object (35) if the detail is greater than the reference value. By performing anti-ageing in the engine after executing, we can improve the processing speed by reducing the calculation amount for rendering.
