 Returns the OpenGL texture Id. A valid Id is returned only. More...
 
virtual void MetalId (void *_textureIdPtr) const =0
 Gets the Metal texture id. A valid Id is obtained only if this is an Metal render texture. The pointer set by this function must be released to an id<MTLTexture> using CFBridgingRelease. More...

virtual void AddRenderPass (const RenderPassPtr &_pass)=0
 Add a render pass to the render target. More...
 
virtual math::Color BackgroundColor () const =0
 Get the background color of the render target. This should be the same as the scene background color. More...
 
virtual void Copy (Image &_image) const =0
 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. More...
 
virtual PixelFormat Format () const =0
 Set the render target image format. More...
 
virtual unsigned int Height () const =0
 Get render target height in pixels. More...
 
virtual void RemoveRenderPass (const RenderPassPtr &_pass)=0
 Remove a render pass from the render target. More...

 Get a render pass by index. More...
 
virtual unsigned int RenderPassCount () const =0
 Get the number of render passes applied to the render target. More...
 
virtual void SetFormat (PixelFormat _format)=0
 Set the render target image format. More...

 Set the render target height in pixels. More...

virtual void Destroy ()=0
 Destroy any resources associated with this object. Invoking any other functions after destroying an object will result in undefined behavior. More...
 
virtual unsigned int Id () const =0
 Get the object ID. This ID will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More...

 Get the object name. This name will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More...
 
virtual void PostRender ()=0
 Post process this object and any of its children after rendering. More...
 
virtual void PreRender ()=0
 Prepare this object and any of its children for rendering. This should be called for each object in a scene just before rendering, which can be achieved by a single call to Scene::PreRender. More...

 Get the Scene that created this object. More...
 

Detailed Description

Represents a off-screen render-texture to which cameras can render images.

Constructor & Destructor Documentation

◆ ~RenderTexture()

virtual ~RenderTexture ( )
virtual

Destructor.

Member Function Documentation

◆ GLId()

virtual unsigned int GLId ( ) const
pure virtual

Returns the OpenGL texture Id. A valid Id is returned only.

Implemented in Ogre2RenderTexture, and BaseRenderTexture< T >.

◆ MetalId()

virtual void MetalId ( void *  _textureIdPtr) const
pure virtual

Gets the Metal texture id. A valid Id is obtained only if this is an Metal render texture. The pointer set by this function must be released to an id<MTLTexture> using CFBridgingRelease.

Parameters
[out]_textureIdPtrthe address of a void* pointer.

Implemented in Ogre2RenderTexture, BaseRenderTexture< T >, BaseRenderTexture< OgreRenderTarget >, and BaseRenderTexture< Ogre2RenderTarget >.
