학습안내 학습목표 씬노드의구성및회전방법을응용하여, 구면카메라및캐릭터컨트롤을구현해본다. 학습내용 구면카메라구현을위한씬노드구성및회전캐릭터컨트롤을위한씬노구구성및회전

카메라및캐릭터컨트롤구현목표 카메라컨트롤 WOW의카메라컨트롤 ( 구면카메라 ) 마우스를이용한좌우패닝, 상하피칭. 휠스크롤을이용한줌인및줌아웃. 캐릭터를중심으로회전됨. 카메라를회전시킬때, 캐릭터는자신의상태유지. 캐릭터컨트롤 WASD 를이용한캐릭터의전후진이동, 좌우이동, 대각선이동

실습 Control(2) 구면카메라구현

bool mousemoved( const OIS::MouseEvent &evt ) myaw->yaw(degree(-evt.state.x.rel)); mpitch->pitch(degree(-evt.state.y.rel)); 실습 mholder->translate(ogre::vector3(0, 0, -evt.state.z.rel * 0.1f)); return true;

학습정리 구면카메라컨트롤 카메라의 Yaw, Pitch 및 Zoom 을위한씬노드를각각따로둠. 캐릭터컨트롤 캐릭터와카메라의회전을분리함 독립적으로회전설정. Yaw Control 을이용하여자체에서회전.
