Detailed Description

DirectionalLight node instances.

openvrml::vrml97_node::directional_light_node::directional_light_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.

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

set_direction eventIn handler.

Parameters:

value	an sfvec3f.
timestamp	the current time.

Exceptions:

std::bad_cast if value is not an sfvec3f.

void openvrml::vrml97_node::directional_light_node::render	(	openvrml::viewer &	viewer,
		rendering_context	context
	)	`[virtual]`

Render the node.

This should be called before rendering any sibling nodes.

Parameters:

viewer	a viewer.
context	a rendering context.
