Destructor. More... | |
virtual void | Destroy ()=0 |
Destroy any resources associated with this object. Invoking any other functions after destroying an object will result in undefined behavior. More... | |
virtual unsigned int | Id () const =0 |
Get the object ID. This ID will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More... | |
virtual std::string | Name () const =0 |
Get the object name. This name will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More... | |
virtual void | PostRender ()=0 |
Post process this object and any of its children after rendering. More... | |
virtual void | PreRender ()=0 |
Prepare this object and any of its children for rendering. This should be called for each object in a scene just before rendering, which can be achieved by a single call to Scene::PreRender. More... | |
virtual ScenePtr | Scene () const =0 |
Get the Scene that created this object. More... | |
