Detailed Description

A standard scene manager.

Class CSceneManager Description: A standard scene manager. It holds all of the objects in a game world. There can be multiple of these in a game at a time, but usually there is only one. An example of when you would want to use a second (or more) scene graph is when you want to layer a second scene over another.

Member Function Documentation

CDirLightPtr LSE_CALL lse::CSceneManager::CreateDirLight ( )

Creates and returns a directional light in the scene. The light is retained until the scene is reset or until explicitly removed from the scene.

Returns:: Returns a shared pointer to a directional light.

LSVOID LSE_CALL lse::CSceneManager::CreateDirLightShadowMapMatrix ( LSUINT32 _ui32Index ) [protected]

Creates the projection matrix for a given directional light.

Parameters:

_ui32Index The index of the directional light with which to create the shadow map.

CDrawableModelInstancePtr LSE_CALL lse::CSceneManager::CreateDrawableModelInstance ( const LSCHAR * _pcFile )

Get a model instance pointer by file name.

Parameters:

_pcFile Path of the file to load, if not loaded already. If the file has already been loaded, it is not loaded again.

Returns:: Returns a shared pointer to a model instance. If failure occurs, an invalid pointer is returned.

LSBOOL LSE_CALL lse::CSceneManager::CreateMainShadowMapTexture ( ) [protected]

Creates the main shadow map texture.

Returns:: Returns false if the main shadow map texture could not be created.

CFloatTexture& LSE_CALL lse::CSceneManager::GetShadowMapTexture ( )

Gets the depth texture used for shadow mapping.

Returns:: Returns the depth texture used for shadow mapping.

LSVOID LSE_CALL lse::CSceneManager::Render	(	CSharedCameraPtr	_cpCam,
		LSBOOL	_bUpdateCamState = `true`
	)

Render the scene with a given camera.

Parameters:

_cpCam	The camera with which to render the scene.
_bUpdateCamState	If true, the camera position, direction, and frustum used to render the scene updated to the those of the given camera.

LSVOID LSE_CALL lse::CSceneManager::Render ( LSE_SCREENS _sSection = LSE_S_FULL_SCREEN )

Render the scene using the given screen render section.

Parameters:

_sSection The section of the screen to render.

LSVOID LSE_CALL lse::CSceneManager::RenderAmbientPassOpaque ( CRenderQueue & _rqSet ) [protected]

Performs an ambient pass.

Parameters:

_rqSet The render queue to render.

LSVOID LSE_CALL lse::CSceneManager::RenderAmbientPassTrans ( CRenderQueue & _rqSet ) [protected]

Performs an ambient pass.

Parameters:

_rqSet The render queue to render.

LSVOID LSE_CALL lse::CSceneManager::RenderDirLightShadowMapOpaque ( LSUINT32 _ui32Index ) [protected]

Creates a shadow map with the given directional light.

Parameters:

_ui32Index The index of the directional light with which to create the shadow map.

LSVOID LSE_CALL lse::CSceneManager::RenderOpaque ( CRenderQueue & _rqSet ) [protected]

Renders the opaque scene objects.

Parameters:

_rqSet The render queue containing the opaque scene objects.

LSVOID LSE_CALL lse::CSceneManager::RenderTrans ( CRenderQueue & _rqSet ) [protected]

Renders the transluscent scene objects.

Parameters:

_rqSet The render queue containing the transluscent scene objects.

LSVOID LSE_CALL lse::CSceneManager::Reset ( )

Reset the scene manager back to scratch.

LSVOID LSE_CALL lse::CSceneManager::SetCamera	(	CSharedCameraPtr	_cpCam,
		LSE_SCREENS	_sScreen = `LSE_S_FULL_SCREEN`
	)

Puts a camera into a given screen slot. Only one camera can be in a slot at a time, and that camera is used for rendering that screen when Render() is called.

Parameters:
