Member Function Documentation

const bounding_volume & openvrml::vrml97_node::group_node::bounding_volume

(

)

const [virtual]

Get the bounding volume.

Returns:

the bounding volume associated with the node.

Reimplemented from openvrml::node.

Reimplemented in openvrml::vrml97_node::anchor_node, and openvrml::vrml97_node::transform_node.

bool openvrml::vrml97_node::group_node::modified

(

)

const [virtual]

Determine whether the node has been modified.

Returns:

true if the node or one of its children has been modified, false otherwise.

Reimplemented from openvrml::node.

Reimplemented in openvrml::vrml97_node::collision_node.

const std::vector< node_ptr > & openvrml::vrml97_node::group_node::children

(

)

const throw () [virtual]

Get the children in the scene graph.

Returns:

the child nodes in the scene graph.

Implements openvrml::grouping_node.

void openvrml::vrml97_node::group_node::activate	(	double	time,
		bool	isOver,
		bool	isActive,
		double *	p
	)			[virtual]

Pass on to enabled touchsensor child.

Implements openvrml::grouping_node.

void openvrml::vrml97_node::group_node::render_nocull	(	openvrml::viewer &	viewer,
		rendering_context	context
	)

because children will already have done the culling, we don't need to repeat it here.

void openvrml::vrml97_node::group_node::do_render_child	(	openvrml::viewer &	viewer,
		rendering_context	context
	)			[protected, virtual]

Render the node.

Render each of the children.

Parameters:

	viewer	a Viewer.
	context	a rendering context.

Reimplemented from openvrml::child_node.

Reimplemented in openvrml::vrml97_node::anchor_node, openvrml::vrml97_node::billboard_node, and openvrml::vrml97_node::transform_node.

void openvrml::vrml97_node::group_node::recalc_bsphere

(

)

[protected]

Recalculate the bounding volume.

Reimplemented in openvrml::vrml97_node::transform_node.
