2 학습안내 학습목표 3D 오브젝트의확대, 축소및회전방법을이해한다. 학습내용 3D 오브젝트의확대및축소 (Scaling) 3D 오브젝트의회전 (Rotation) 변홖공갂 (Transform Space)

3 SceneNode 의크기변홖 (Scale) void setscale ( Real x, Real y, Real z) void setscale ( const Vector3 & scale ) 씬노드에속해있는엔터티들의크기확장및축소. 씬노드의절대적스케일값을설정.

4 SceneNode 의크기변홖 (Scale) void scale ( Real x, Real y, Real z) void scale ( const Vector3 & scale ) 씬노드에속해있는엔터티들의크기확장및축소. 이미크기변홖된노드에적용하면앞서했었던크기변홖의위에적용됨. scale(vector3(2,2,2)) 를두번적용하면, setscale(vector3(4,4,4)) 와같음.

5 SceneNode 의크기변홖 (Scale) void setinheritscale ( bool inherit ) 장면노드의하위자식노드에게도크기변화가적용되는지결정. 디폴트값은 true

6 실습 Scale 엔터티크기변환

8 main.cpp (2) bool framestarted(const FrameEvent &evt) { if (mkeyboard->iskeydown(ois::kc_1)) mprofessornode->setscale(1.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_2)) mprofessornode->setscale(2.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_3)) mprofessornode->setscale(3.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_e)) mprofessornode->scale(1.1f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_i)) mninjanode->setinheritscale(!mninjanode->getinheritscale()); 실습 } return true;

9 실행화면 키이입력 1,2,3,E,I 에따라다양한스케일실험.

10 if (mkeyboard->iskeydown(ois::kc_1)) mprofessornode->setscale(1.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_2)) mprofessornode->setscale(2.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_3)) mprofessornode->setscale(3.0f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_e)) mprofessornode->scale(1.1f, 1.0f, 1.0f); else if (mkeyboard->iskeydown(ois::kc_i)) mninjanode->setinheritscale(!mninjanode->getinheritscale());

11 SceneNode 의회전 (Rotation) void pitch (const Radian &angle, TransformSpace relativeto=ts_local) x 축을회전축으로하여주어진각도만큼회전. Y Z X

12 SceneNode 의회전 (Rotation) void yaw (const Radian &angle, TransformSpace relativeto=ts_local) y 축을회전축으로하여주어진각도만큼회전. Y Z X

13 SceneNode 의회전 (Rotation) void roll (const Radian &angle, TransformSpace relativeto=ts_local) z 축을회전축으로하여주어진각도만큼회전. Y Z X
