Detailed Description

Interface for dynamic creation of scene nodes.

To be able to add custom scene nodes to Nirtcpp and to make it possible for the scene manager to save and load those external scene nodes, simply implement this interface and register it in you scene manager via ISceneManager::registerSceneNodeFactory. Note: When implementing your own scene node factory, don't call ISceneNodeManager::grab() to increase the reference counter of the scene node manager. This is not necessary because the scene node manager will grab() the factory anyway, and otherwise cyclic references will be created and the scene manager and all its nodes won't get deallocated.

Member Function Documentation

addSceneNode() [1/2]

virtual ISceneNode * nirt::scene::ISceneNodeFactory::addSceneNode ( const c8 *  typeName, ISceneNode *  parent = 0  )

pure virtual

adds a scene node to the scene graph based on its type name

Parameters

typeName	Type name of the scene node to add.
parent	Parent scene node of the new node, can be null to add the scene node to the root.

Returns

Returns pointer to the new scene node or null if not successful. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

addSceneNode() [2/2]

virtual ISceneNode * nirt::scene::ISceneNodeFactory::addSceneNode ( ESCENE_NODE_TYPE  type, ISceneNode *  parent = 0  )

pure virtual

adds a scene node to the scene graph based on its type id

Parameters

type	Type of the scene node to add.
parent	Parent scene node of the new node, can be null to add the scene node to the root.

Returns

Returns pointer to the new scene node or null if not successful. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

getCreateableSceneNodeType()

virtual ESCENE_NODE_TYPE nirt::scene::ISceneNodeFactory::getCreateableSceneNodeType ( u32  idx ) const

pure virtual

returns type of a creatable scene node type

Parameters

idx	Index of scene node type in this factory. Must be a value between 0 and getCreatableSceneNodeTypeCount()

getCreateableSceneNodeTypeName() [1/2]

virtual const c8 * nirt::scene::ISceneNodeFactory::getCreateableSceneNodeTypeName ( ESCENE_NODE_TYPE  type ) const

pure virtual

returns type name of a creatable scene node type

Parameters

type	Type of scene node.

Returns

: Returns name of scene node type if this factory can create the type, otherwise 0.

getCreateableSceneNodeTypeName() [2/2]

virtual const c8 * nirt::scene::ISceneNodeFactory::getCreateableSceneNodeTypeName ( u32  idx ) const

pure virtual

returns type name of a creatable scene node type by index

Parameters

idx	Index of scene node type in this factory. Must be a value between 0 and getCreatableSceneNodeTypeCount()
