1 게임엔진 제 13 강 ofusion 씬구성 이대현교수 한국산업기술대학교게임공학과

2 학습목차 Ofusion 을이용한 export Export 된씬의재현 씬노드애니메이션을이용한수동카메라트래킹

3 ofusion OGRE3D 엔진용 3D MAX 익스포터

4 ofusion 의특징 Realtime Viewport 3D MAX 안에서 OGRE3D 용씬을구성하고, 실시간으로확인및변환이가능 Material System 다양한재질스크립트구현가능 Shader System GPU 파라미터의설정및실시간확인가능 Export 가능 (Professional Edition) Content exporter system 씬, 광원, 카메라, 애니메이션등등 Scene Loader Library OGRE3D 엔진용로더소스제공

5 ofusion 의설치 3D Max 를설치한후, ofusion 인스톨러를이용하여설치하여, 3D Max 의메뉴에 ofusion 항목이생성됨.

6 Exporter 메뉴

7 출력된파일의종류.osm - 카메라, 라이트, 그림자, 애니메이션등 Export 한 Scene 에대한전반적인정보를가지고있음..mesh 3D 메쉬기하정보.material 메쉬재질정보.skeleton 골격애니메이션정보 그외각종 image 파일들 Exporter option 의 Copy Texture 체크

27 실습과제 #8 카메라트래킹설계 원거리에서카메라로지형위의닌자를포착하면서시작. 닌자로가까이카메라를움직이면서멋진 (?) 카메라트래킹으로접근함. 닌자에가까이오면카메라트래킹을멈추고대전모드로들어감.
