Detailed Description

Billboard node instances.

openvrml::vrml97_node::billboard_node::billboard_node	(	const node_type &	type,
		const scope_ptr &	scope
	)

Construct.

Parameters:

type	the node_type associated with the node instance.
scope	the scope to which the node belongs.

const mat4f openvrml::vrml97_node::billboard_node::billboard_to_matrix	(	const billboard_node &	node,
		const mat4f &	modelview
	)	`[static]`

Get the bounding box transformation matrix.

Parameters:

node	a pointer to a billboard_node.
modelview	input ModelView transformation matrix.

void openvrml::vrml97_node::billboard_node::process_set_axisOfRotation	(	const field_value &	value,
		double	timestamp
	)	throw (std::bad_cast) `[private]`

set_axisOfRotation eventIn handler.

Parameters:

value	an sfvec3f.
timestamp	the current time.

Exceptions:

std::bad_cast if value is not an sfvec3f.
