~Composite()

virtual scg::Composite::~Composite ( )

pure virtual

Destructor.

Member Function Documentation

acceptPost()

virtual void scg::Composite::acceptPost ( Traverser *  traverser )

virtual

Accept traverser after traversing sub-tree (visitor pattern).

Reimplemented in scg::Camera, scg::Light, scg::Transformation, and scg::Group.

addChild()

Composite* scg::Composite::addChild

(

NodeSP

child

)

Add child to composite node.

Returns

this pointer for method chaining

Examples

scg3_minimal_example.cpp, and scg3_table_scene_example.cpp.

destroy()

virtual void scg::Composite::destroy ( )

virtual

Remove node from scene graph, destroy nodes of sub-tree (if any).

Reimplemented from scg::Node.

removeChild() [1/2]

Composite* scg::Composite::removeChild	(	Node *	node,
		bool &	result
	)

Remove child from composite node.

Parameters

node	pointer to node to be removed
result	true if node has been found and removed

Returns

this pointer for method chaining

removeChild() [2/2]

Composite* scg::Composite::removeChild

(

Node *

node

)

Remove child from composite node (ignore result).

Returns

this pointer for method chaining

renderPost()

virtual void scg::Composite::renderPost ( RenderState *  renderState )

virtual

Render node after traversing sub-tree, e.g., to restore previous state.

Reimplemented in scg::Camera, scg::Light, scg::Transformation, and scg::Group.

traverse()

virtual void scg::Composite::traverse ( Traverser *  traverser )

virtual

Traverse node tree (depth-first, pre-order) with given traverser.

Implements scg::Node.
