Constructor & Destructor Documentation

openvrml::vrml97_node::transform_node::transform_node	(	const node_type &	type,
		const boost::shared_ptr< openvrml::scope > &	scope
	)

Construct.

Parameters:

	type	the node_type associated with the instance.
	scope	the scope that the new node will belong to.

Reimplemented from openvrml::transform_node.

openvrml::vrml97_node::transform_node::~transform_node

(

)

throw () [virtual]

Destroy.

Implements openvrml::transform_node.

Member Function Documentation

const bounding_volume & openvrml::vrml97_node::transform_node::bounding_volume

(

)

const [virtual]

Get the bounding volume.

Returns:

the bounding volume associated with the node.

Reimplemented from openvrml::vrml97_node::group_node.

const mat4f & openvrml::vrml97_node::transform_node::transform

(

)

const throw () [virtual]

Get the transformation associated with the node as a matrix.

Returns:

the transformation associated with the node.

Implements openvrml::transform_node.

void openvrml::vrml97_node::transform_node::do_render_child	(	openvrml::viewer &	viewer,
		rendering_context	context
	)			[private, virtual]

Render the node.

Parameters:

	viewer	a Viewer.
	context	the rendering context.

Reimplemented from openvrml::vrml97_node::group_node.

void openvrml::vrml97_node::transform_node::recalc_bsphere

(

)

[private]

Recalculate the bounding volume.

Reimplemented from openvrml::vrml97_node::group_node.

void openvrml::vrml97_node::transform_node::update_transform

(

)

const throw () [private]

Update transform.

If transform_dirty is true, resynchronize the cached matrix transform with the node fields; otherwise do nothing.

Note:

P' = T × C × R × SR × S × -SR × -C × P
