Detailed Description

Simple, copying manager/factory for RenderTextures.

This is only used as the last fallback if both PBuffers and FBOs aren't supported.

Member Function Documentation

◆ createRenderTexture()

RenderTexture* Ogre::GLCopyingRTTManager::createRenderTexture	(	const String &	name,
		const GLSurfaceDesc &	target,
		bool	writeGamma,
		uint	fsaa
	)

inlineoverridevirtual

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

◆ checkFormat()

bool Ogre::GLCopyingRTTManager::checkFormat ( PixelFormat format )

inline

◆ bind()

void Ogre::GLCopyingRTTManager::bind ( RenderTarget * target )

inlineoverridevirtual

Bind a certain render target.

Note: only needed for FBO RTTs

Reimplemented from Ogre::GLRTTManager.

◆ unbind()

void Ogre::GLCopyingRTTManager::unbind ( RenderTarget * target )

overridevirtual

Unbind a certain render target.

This is called before binding another RenderTarget, and before the context is switched. It can be used to do a copy, or just be a noop if direct binding is used.

Note: only needed for Copying or PBuffer RTTs
