Member Function Documentation

◆ AddRenderPass()

virtual void AddRenderPass ( const RenderPassPtr & _pass )

pure virtual

Add a render pass to the render target.

Parameters

[in] _pass New render pass to add

Implemented in BaseRenderTarget< T >, BaseRenderTarget< Ogre2Object >, and BaseRenderTarget< OgreObject >.

Referenced by RenderTarget::~RenderTarget().

◆ BackgroundColor()

virtual math::Color BackgroundColor ( ) const

pure virtual

Get the background color of the render target. This should be the same as the scene background color.

Returns: Render target background color.

Implemented in Ogre2RenderTarget, BaseRenderTarget< T >, BaseRenderTarget< Ogre2Object >, BaseRenderTarget< OgreObject >, and OgreRenderTarget.

Referenced by RenderTarget::~RenderTarget().

◆ Copy()

virtual void Copy ( Image & _image ) const

pure virtual

Write rendered image to given Image. The RenderTarget will convert the underlying image to the specified format listed in the given Image. However if the given image is not of the correct size no work will be done. Calling this function before an image has been rendered will result in undefined behavior.

Parameters

[out] _image Image to which output will be written

Implemented in Ogre2RenderTarget, and OgreRenderTarget.
