Detailed Description

A scene graph node that can have children.

GroupNode is the only node type in the scene graph that is allowed to have children.

This class cannot be directly instantiated. Instead, use Scene.

Member Function Documentation

SceneNodeType sv::GroupNode::NodeType ( ) const

inlineoverridevirtual

Returns

SceneNodeType::kGroupNode

Implements sv::SceneNode.

void sv::GroupNode::TransformChanged ( )

overrideprotectedvirtual

Internal method, used to enable lazy matrix computations.

Called when the node's transform changes (e.g., via SetTranslation, SetRotation, or SetScale) or when a parent's transform changes. Also triggers a call to BoundingBoxChanged()

Reimplemented from sv::SceneNode.

const AxisAlignedBox& sv::GroupNode::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.
