getCameraUniformObject()

CameraUniformObject GraphicsCameraManager::getCameraUniformObject ( const Camera & camera, GraphicsUpdateArguments & args ) const

protected

Builds a CameraUniformObject from a Camera and update arguments.

Parameters

[in]	camera	The camera.
[in]	args	The update arguments.

Returns

The populated uniform object.

overrideMaterial()

UUID GraphicsCameraManager::overrideMaterial ( ) const

inline

Returns the override material UUID.

Returns

The override material UUID.

Definition at line 94 of file GraphicsCameraManager.h.

References m_override_material.

setCamera()

void GraphicsCameraManager::setCamera ( const UUID & camera )

inline

Sets the camera to manage.

Parameters

[in]

camera

The camera UUID.

Definition at line 85 of file GraphicsCameraManager.h.

References m_camera.

uniformObject()

const CameraUniformObject & GraphicsCameraManager::uniformObject ( ) const

inline

Returns the current camera uniform data.

Returns

Reference to the uniform object.

Definition at line 97 of file GraphicsCameraManager.h.

References m_camera_uniform.

updateUniformBuffer()

virtual void GraphicsCameraManager::updateUniformBuffer ( GraphicsUpdateArguments & args )

virtual
