Detailed Description

Interface providing functions to manage a group or type of Cameras in a specific way. CameraManager handle one "active camera" for rendering as m_activeCamera; this rendering camera has no Component associated, and it can retrieve it's data from any managed camera with activate(index). Manipulator and renderer can access (and even store as a visiting ptr) this data with getActiveCamera() Default camera data is used to intializad camera. Client code can set this static data to control default camera initialization.

Member Function Documentation

◆ activate()

void Ra::Engine::Scene::CameraManager::activate ( Core::Utils::Index index )

activate camera at index given its index. index-th camera data is copied to the "active camera" stored explicitly by the manager. width and height of previous active camera is kept during this process, since it's likely to be screen size, while index-th camera width height might be something else. When a camera is activated, the frame of the active camera is computed to take the entity's transformation into account.

Parameters

index camera's index to activate, if invalid or out of bound, activation is ignored.

Definition at line 39 of file CameraManager.cpp.

◆ generateTasks()

void Ra::Engine::Scene::CameraManager::generateTasks	(	Core::TaskQueue *	taskQueue,
		const Engine::FrameInfo &	frameInfo
	)

overridevirtual

Pure virtual method to be overridden by any system. Must register in taskQueue the operations that must be done ate each frame.

Parameters

taskQueue	The queue to fill
frameInfo	Information about the current frame (

See also: FrameInfo)

Implements Ra::Engine::Scene::System.

Here is the call graph for this function:

◆ getCameraIndex()

Ra::Core::Utils::Index Ra::Engine::Scene::CameraManager::getCameraIndex ( const CameraComponent * cam )

virtual

get camera component's index, if this component is managed.

Returns: valid index if component is managed, invalid index in other case.

Definition at line 64 of file CameraManager.cpp.

◆ handleAssetLoading()

void Ra::Engine::Scene::CameraManager::handleAssetLoading	(	Entity *	entity,
		const Core::Asset::FileData *	data
	)

overridevirtual

Factory method for component creation from file data. From a given file and the corresponding entity, the system will create the corresponding components, add them to the entity, and register the component.

Note: : Issue #325 - As this method register components and might also manage each component outside the m_components vectors (e.g in a buffer on the GPU) the methods, the registerComponent and unregister*Component must be virtual method that could be overriden.

Reimplemented from Ra::Engine::Scene::System.

Definition at line 98 of file CameraManager.cpp.

◆ registerComponent()

void Ra::Engine::Scene::CameraManager::registerComponent	(	const Entity *	entity,
		Component *	component
	)
