Anne的IT小天地

void getMeshInfo(Entity* ent) { MeshPtr mesh = ent->getMesh(); bool added_shared = false; size_t current_offset = 0; size_t shared_offset = 0; size_t index_offset = 0; size_t next_o

Ogre定义的三种灯光类型及使用1. LT_POINT = 0,//点光源Point light sources give off light equallyin all directions, so require only position not directionlight = mSceneMgr->createLight("pointLight");light->set

利用Ogre自带的Plane类绘制平面//1.定义平面对象Plane plane;//2.设置相关属性plane.normal =Vector3(0,-1,1);//法向量plane.d = 0;//与世界原点的距离 //3.创建MeshMeshManager::getSingleton().createPlane("平面的名字","所属的资源组", "平面对象", "平

1.跳过ogre配置窗口：restoreConfig()bool configure(void){ if(mRoot->restoreConfig() || mRoot->showConfigDialog()) //if(mRoot->showConfigDialog()) { mWindow = mRoot->initialise(true, OGRE_WIN_TITLE);

1.本地坐标转为世界坐标void local2World(const Vector3 locP, Vector3 &worldP, const SceneNode* node){ Matrix4 worldMat; node->getWorldTransforms(&worldMat); //获取该物体的世界坐标矩阵 worldP = worldMat * locP;}2.世

void createCube(){ //1.创建Mesh对象 MeshPtr msh = MeshManager::getSingleton().createManual("Cube", "General"); SubMesh* sub1 = msh->createSubMesh("1"); //2.定义顶点数量、信息 const float sqrt13

1. 鼠标纹理贴图2. 鼠标材质脚本material mouse{ technique { pass { scene_blend alpha_blend depth_check off texture_unit { tex_address_mode clamp texture mouse.png } } }}

1.Ogre相关类（1）HardwarePixelBuffer类（2）PixelBox类A primitive describing a volume (3D), image (2D) or line (1D) of pixels in memory.In case of a rectangle, depth must be 1. Pixels are stor

Ogre中场景查询相关类基类SceneQuery、其子类RegionSceneQuery区域查询、RaySceneQuery射线查询、IntersectionSceneQuery相交查询每种场景查询都有对应的SceneQueryResult和SceneQueryListener查询结果分为场景中可移动的物体元素（MovableObject）和世界信息（复杂场景中的地形等不变的元素）

Ogre中与节点动画相关的类：（1）Ogre::Animation（2）Ogre::AnimationState（3）Ogre::NodeAnimationTrack（4）Ogre::TransformKeyFrame节点动画的使用步骤：//1.创建动画对象Animation* anim= mSceneMgr->create

//【Ritter90】逼近包围球的计算----------------------------------------------------------------------//查找相隔最远的两个顶点void MostSeparatedPointsOnAABB(int &imin, int &imax, Vector3 pt[], int numPts){ int minx = 0,

1.天空盒（立方体）六面：stevecube_up,stevecube_dn,stevecube_lf,stevecube_rt,stevecube_fr,stevecube_bk.jpg创建：mSceneMgr->setSkeBox(是否启用，材质名，skybox与camera的距离，渲染级别)            mSceneMgr->setSkyBox(true,"Exampl

1.material文件定义shader 参数：param_named arr custom2.cg文件定义数组参数：uniform float4 arr注意：cg中必须使用传入的数组，否则会报错。3.主程序中更新数组信息float m_arr[10][4];Ogre::MaterialPtr mat =  Ogre::MaterialManager::getSin
