Constructor & Destructor Documentation

LayerSceneGraph::SceneNode::SceneNode

(

)

Dafault constructor. Instances a transform and a world transform matrix and set its parent as NULL.

LayerSceneGraph::SceneNode::~SceneNode ( )

virtual

Destructor. Releases and deletes all children of this node.

Member Function Documentation

void LayerSceneGraph::SceneNode::addChild

(

SceneNode *

s

)

Adds another node as a child of this node.

void LayerSceneGraph::SceneNode::draw ( )

virtual

*This method updates this node world matrix based on its parent world matrix. It is necessary for correct drawing.

Todo:

think about a better update strategy

Reimplemented in LayerSceneGraph::Layer, and LayerSceneGraph::Impostor.

vector< SceneNode * >::const_iterator LayerSceneGraph::SceneNode::getChildteratorEnd

(

)

vector< SceneNode * >::const_iterator LayerSceneGraph::SceneNode::getChildteratorStart

(

)

SceneNode * LayerSceneGraph::SceneNode::getParent

(

)

Return this node's parent.

Vector3 LayerSceneGraph::SceneNode::getPosition

(

)

Returns this node position in its local coordinate system.

Matrix4 LayerSceneGraph::SceneNode::getTransform

(

)

Returns the local transformation matrix of this node

Matrix4 LayerSceneGraph::SceneNode::getWorldTransform

(

)

Returns the world transform matrix of this node. This matrix represents the transformation of this node relative to the complete scene.

void LayerSceneGraph::SceneNode::onTouch ( )

virtual

This methods determines how this node reacts when it is intercepted by a ray due to touch interaction

SceneNode * LayerSceneGraph::SceneNode::removeChild

(

)

Removes the last child added from this node children vector.

void LayerSceneGraph::SceneNode::setTransform

(

Matrix4

m

)

Sets a new transform matrix for this node.

void LayerSceneGraph::SceneNode::setWorldTransform

(

Matrix4

m

)

Sets a new world transform for this node.
