Detailed Description

Same as UnitInOut but renders text onto the output.

The text is displayed in 2D ortho mode. This class is wrapper for the osgText::Text class, so check it for more information about the text support.

Member Function Documentation

virtual bool osgPPU::UnitText::noticeBeginRendering	(	osg::RenderInfo &	,
		const osg::Drawable *
	)			[protected, virtual]

Here the FBO will be applied, so that Unit can render its output to attached textures. If you overwrite this method in derived class, so you have to take care about FBO handling.

Reimplemented from osgPPU::UnitInOut.
