Detailed Description

Scene node that contains a list of drawable objects.

Member Function Documentation

void sv::DrawNode::Add

(

const Drawable::Ptr &

drawable

)

Attaches a generic drawable item to the node.

The node can have multiple drawable objects, and they are always drawn in the order that they are added, relative to each other.

void sv::DrawNode::Add	(	const GeometryResource::Ptr &	geometry,
		const MaterialResource::Ptr &	material
	)

Convenience method to attach a drawable object from a geometry resource and a material resource.

This method is equivalent to:

draw_node->Add(Drawable::Create(geometry, material));

void sv::DrawNode::BoundingBoxChanged ( )

overrideprotectedvirtual

Internal method, used to enable lazy bounding box computations.

Called when the node's bounding box changes, or when a child's bounding box changes.

Reimplemented from sv::SceneNode.

const AxisAlignedBox& sv::DrawNode::WorldBoundingBox ( )

overridevirtual

Retrieve the world-space bounding box of the node and all of its children (if applicable).

Used internally in view frustum culling and selection queries.

Implements sv::SceneNode.
