Member Enumeration Documentation

◆ OgreRenderPathType

The type of rendering path used by the rendering engine.

Enumerator
NONE 

No rendering is done.

VERTEX 

Most basic rendering, with least fidelity.

FORWARD 

Utilizes the RTT shader system.

DEFERRED 

Utilizes deferred rendering. Best fidelity.

RENDER_PATH_COUNT 

Count of the rendering path enums.

Member Function Documentation

◆ AddResourcePath()

void AddResourcePath ( const std::string _path)
overridevirtual

Add path to media resource location.

Parameters
[in]_pathAbsolute path to resource location

Reimplemented from BaseRenderEngine.

◆ CreateRenderWindow()

)

◆ CreateSceneImpl()

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

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.
