	)

virtual

initialize the RTT with a texture format and sampling/wrapping hints

virtual bool makVrv::DtGlRenderTexture::init ( unsigned int glColorTexId )

virtual

Initialize the RTT color from an existing OpenGL Texture.

Assumes the texture sampling and wrapping hints have already been setup. If DtGlRenderTexture was created with multiple samples, this texture needs to match.

virtual bool makVrv::DtGlRenderTexture::initDepth ( DtGlImageType depthFormat = D32 )

virtual

Optionally create a depth texture to go with the RTT that is bound when drawing into.

virtual bool makVrv::DtGlRenderTexture::initDepth ( unsigned int glDepthTexId )

virtual

Initialize depth texture from an existing OpenGL texture.

Assumes the texture sampling and wrapping hints have already been setup.

virtual void makVrv::DtGlRenderTexture::activateForDrawingInto	(	bool	shouldClear = `true`,
		bool	setViewport = `true`
	)

virtual

activate this RTT for drawing into. Binds the internal FBO and color/depth targets

virtual void makVrv::DtGlRenderTexture::copyFromFramebuffer	(	unsigned int	srcFbo,
