Irrlicht的FPS类型摄像头节点的基本使用技巧

virtual IAnimatedMeshSceneNode* irr::scene::ISceneManager::addAnimatedMeshSceneNode (

              IAnimatedMesh* mesh,

              ISceneNode* parent = 0,

              s32 id = -1,

              const core::vector3df& position = (0, 0, 0),

              const core::vector3df& rotation = (0 ,0 , 0),

              const core::vector3df& scale = (1.0f, 1.0f, 1.0f),

              bool alsoAddIfMeshPointerZero = false)

[pure virsual]

 

Adds a scene node for rendering an animated mesh model.

Parameters:

	mesh,:	Pointer to the loaded animated mesh to be displayed.
	parent,:	Parent of the scene node. Can be NULL if no parent.
	id,:	Id of the node. This id can be used to identify the scene node.
	position,:	Position of the space relative to its parent where the scene node will be placed.
	rotation,:	Initital rotation of the scene node.
	scale,:	Initial scale of the scene node.
	alsoAddIfMeshPointerZero,:	Add the scene node even if a 0 pointer is passed

 

Returns:

Pointer to the created scene node. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

 

使用技巧: 以摄像机(camera)为父节点(parent), 其position坐标为相对父节点(parent)位置坐标, 可以用该函数(function)把模型(mesh)绑定在摄像机(camera)上, 当摄像机(camera),比如说一个FPS(first person shoot)摄像机移动的时候, 绑定在摄像机(camera)上的模型(mesh)也随之移动, 可以简单的构造一个类似CS的第一人称视角.

 

IRRLICHT提供的2种比较特别但是很广泛使用的摄像机模拟视角和操作分别是FPS,和MAYA的典型操作.使用非常简单.
