Ogre2RenderTexture ( )

protected

Constructor.

◆ ~Ogre2RenderTexture()

virtual ~Ogre2RenderTexture ( )

virtual

Destructor.

Member Function Documentation

◆ BuildTarget()

virtual void BuildTarget ( )

protectedvirtual

Build the render texture.

◆ Destroy()

virtual void Destroy ( )

overridevirtual

Destroy the render target.

Implements Ogre2RenderTarget.

◆ DestroyTarget()

virtual void DestroyTarget ( )

protectedvirtual

Destroy the render texture.

◆ GLId()

virtual unsigned int GLId ( ) const

overridevirtual

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

Reimplemented from BaseRenderTexture< Ogre2RenderTarget >.

◆ PostRender()

virtual void PostRender ( )

overridevirtual

Post process this object and any of its children after rendering.

Reimplemented from Ogre2RenderTarget.

◆ PreRender()

virtual void PreRender ( )

overridevirtual

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.

Reimplemented from Ogre2RenderTarget.

◆ RebuildTarget()

virtual void RebuildTarget ( )

overrideprotectedvirtual

Rebuild the render target.

Implements Ogre2RenderTarget.

◆ RenderTarget()

virtual Ogre::RenderTarget* RenderTarget ( ) const

overridevirtual

Get a pointer to the ogre render target containing the results of the render.

Implements Ogre2RenderTarget.

◆ SetOgreTexture()

void SetOgreTexture ( Ogre::Texture * _ogreTexture )

Do not call this function directly.

It's used to keep ABI compatibility to sync ogreTexture with the internal pointer from our base class.

Parameters

[in] _ogreTexture texture from Ogre2RenderTargetPrivate::ogreTexture[1]

Member Data Documentation

◆ ogreTexture

Ogre::Texture* ogreTexture = nullptr

protected

Unused. Kept for ABI reasons.

Just in case we set this value to Ogre2RenderTargetPrivate::ogreTexture[1] which is what most client applications may want.
