Detailed Description

Ogre2 render engine class. A singleton class that manages the underlying ogre2 render engine, loads its plugins, and creates resources needed for the engine to run.

Constructor & Destructor Documentation

◆ ~Ogre2RenderEngine()

virtual ~Ogre2RenderEngine ( )
virtual

Destructor.

Member Function Documentation

◆ AddResourcePath()

void AddResourcePath ( const std::string _uri)
overridevirtual

Add path to resource in ogre2's resource manager.

Parameters
[in]_uriResource path in the form of an uri

Reimplemented from BaseRenderEngine.

◆ CreateRenderWindow()

std::string CreateRenderWindow ( const std::string _handle,
const unsigned int  _width,
const unsigned int  _height,
const double  _ratio,
const unsigned int  _antiAliasing 
)

Create a render window.

Parameters
[in]_handleHandle of native window which the render window will attach
[in]_widthWidth of render window
[in]_heightHeight of render window
[in]_ratioDevice pixel ratio (typically needed for retina displays)
[in]_antiAliasingAnti-aliasing level

◆ CreateSceneImpl()

virtual ScenePtr CreateSceneImpl ( unsigned int  _id,
const std::string _name 
)
overrideprotectedvirtual

Create a scene.

Parameters
[in]_idUnique scene Id
[in]_nameName of scene

Implements BaseRenderEngine.

◆ Destroy()

virtual void Destroy ( )
overridevirtual

Destroys all scenes created by render-engine and releases all loaded resources. This should be called when the given render-engine will no longer be used during runtime.

Returns
True if the render-engine was successfully destroyed

Reimplemented from BaseRenderEngine.

◆ FSAALevels()

std::vector<unsigned int> FSAALevels ( ) const

Get a list of all supported FSAA levels for this render system.

Returns
a list of FSAA levels

◆ GraphicsAPI()

Get the render engine's graphics API Note: Do not merge this forward. This has been changed to virtual function in ign-rendering7.

Returns
The graphics API enum class

◆ HlmsCustomizations()

Ogre2IgnHlmsCustomizations& HlmsCustomizations ( )

Retrieves Hlms customizations for tweaking them.

Returns
Ogre HLMS customizations

◆ HlmsPbsTerraShadows()

Ogre::HlmsPbsTerraShadows* HlmsPbsTerraShadows ( ) const

◆ InitImpl()

virtual bool InitImpl ( )
overrideprotectedvirtual

Initialize the render engine.

Returns
True if the operation is successful

Implements BaseRenderEngine.

◆ IsEnabled()

virtual bool IsEnabled ( ) const
overridevirtual

Determines if the render-engine can be used. Despite loading and initializing the render-engine, it may not be possible to use due to hardware capabilities of the runtime system.

Returns
True if the render-engine can be used

Reimplemented from BaseRenderEngine.

◆ LoadImpl()

virtual bool LoadImpl ( const std::map< std::string, std::string > &  _params)
overrideprotectedvirtual

Engine implementation of Load function.

Parameters
[in]_paramsParameters to be passed to the render engine.

Implements BaseRenderEngine.

◆ Name()

virtual std::string Name ( ) const
overridevirtual

Get name of the render-engine.

Returns
The render-engine name

Implements RenderEngine.

◆ OgreRoot()

virtual Ogre::Root* OgreRoot ( ) const
virtual

Get the ogre2 root object.

Returns
ogre2 root object

◆ OgreWindow()

Ogre::Window* OgreWindow ( ) const

return the ogre window

◆ OverlaySystem()

Ogre::v1::OverlaySystem* OverlaySystem ( ) const

◆ Scenes()

virtual SceneStorePtr Scenes ( ) const
overrideprotectedvirtual

Get a pointer to the list of scenes managed by the render engine.

Returns
list of scenes

Implements BaseRenderEngine.

◆ TerraWorkspaceListener()

Ogre::CompositorWorkspaceListener* TerraWorkspaceListener ( ) const
