cull()

std::vector< const helios::scene::SceneNode * > helios::scene::CullNoneStrategy::cull (const helios::scene::CameraSceneNode * cameraSceneNode, const helios::scene::SceneNode & root)

inline nodiscard virtual

Returns all SceneNode of the specified scene, regardless of their visibility relative to the CameraSceneNode's camera view frustum.

Parameters

cameraSceneNode	The camera defining the view frustum.
root	The parent of the hierarchy to cull.

Returns

A vector with const pointers to the SceneNodes found under `root`.

Protected Member Functions

cull()

void helios::scene::CullNoneStrategy::cull (std::vector< const helios::scene::SceneNode * > & nodes, const SceneNode & node)

inline protected

Internal function to populate the vector recursively with the node and its children.

Parameters

nodes	The vector holding the const pointers to the SceneNodes
node	The current node to process. This node is added to nodes, then this method is called for each child node of node.
