Enum documentation

enum class SceneNodeSemanticDataIDX

This enum holds the idx values for the vector of various types of IDs that can be rendered via semantic sensors.

Enumerators
SEMANTIC_ID	The semantic ID corresponding to the object represented by this scene node. The semantic category of a node. This value is used to render attached Drawables with Semantic sensor when no perVertexObjectIds are present.
OBJECT_ID	The object ID of the object represented by this scene node. This value will be set to ID_UNDEFINED if the object is deleted without removing the scene node/drawable.
DRAWABLE_ID	The drawable ID that draws this scene node.
NUM_SEMANTIC_IDS	Insert the index of a new ID to represent in semantic observations above this entry.

enum class SceneNodeTag: Magnum::UnsignedShort

Enumerators
Leaf	Set node as Leaf node, so no children nodes are allowed

Function documentation

template<typename Callable>
void preOrderTraversalWithCallback(const SceneNode& node, Callable&& cb)

Perform a pre-order traversal and invoke a callback at each node.

Parameters
node	Root node for this traversal
cb	Callback which will be called with each SceneNode

template<typename Callable>
void preOrderTraversalWithCallback(SceneNode& node, Callable&& cb)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

template<typename Feature, typename Callable>
void preOrderFeatureTraversalWithCallback(const SceneNode& node, Callable&& cb)

Perform a pre-order traversal and invoke a callback on features of the desired type.

Template parameters
Feature	Feature type to invoke callback on
Callable
Parameters
node	Root node for this traversal
cb	Callback which will be called with each feature

template<typename Feature, typename Callable>
void preOrderFeatureTraversalWithCallback(SceneNode& node, Callable&& cb)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void setSemanticIdForSubtree(SceneNode* node, int semanticId)

Set the semantic ID of a scene graph subtree.

Parameters
node	Root node of the subtree.
semanticId	Semantic ID to apply to the subtree.

void setSemanticInfoForSubtree(SceneNode* node, const std::vector<int>& _semanticIDs)

Set the semantic and instance IDs of a scene graph subtree.

Parameters
node	Root node of the subtree.
_semanticIDs
