Abstract: A texture map making method and a system of a 3D model under 2D environment are provided to configure UV mapping areas whose shapes are the same as each polygon of 3D model data, thereby almost removing partial distortion of a texture image. A texture map set of 3D model date is generated(S320). A UV map set obtained by unfolding the 3D model data on a designated plan among multidirectional planes is obtained(S330). A 2D image making task is conducted on the generated UV map set(S340). Until a final texture map set is completed, the UV map generating, image making, and mapping processes are repeated(S350). The final texture map set is added to the 3D model date, and the 3D model data is outputted(S360). The texture map set includes UV mapping coordinates information corresponding to all polygons.

Abstract: 본 발명은 2차원 환경에서 3차원 모델의 텍스쳐 맵 제작 방법 및 시스템에 관한 것으로, 종래의 방법은 텍스쳐 맵을 위한 이미지 저작 작업보다 UV 전개된 UV 매핑 좌표 정보들을 재지정하는 데 몇 배의 시간을 낭비하고 텍스쳐 이미지의 부분 왜곡을 수반하는데 비해 본 발명은 개념적으로 텍스쳐 맵을 몇 개로 분할하는 방식으로(각 분할된 텍스쳐 맵은 하나의 UV 맵에 해당) 자동화된 UV 전개 방법을 사용하여 UV 매핑 좌표 정보들을 재지정하는 데에 소요되는 불필요한 시간을 줄이고 3차원 모델 데이터의 각 다각형과 동형의 UV 매핑 영역을 구성하여 텍스쳐 이미지의 부분 왜곡을 거의 없애주는 이점이 있다.
