Detailed Description

This class encapsulates a G-Buffer.

Basically, this is a collection of per-pixel geometry information.

Constructor & Destructor Documentation

PostprocessorInput() [1/3]

WGEPostprocessor::PostprocessorInput::PostprocessorInput ( std::vector< osg::ref_ptr< osg::Texture2D > >  from )

explicit

Constructs an instance from a given list of textures.

The order in the list define color, normal, parameter, tangent, depth. There are no restrictions to the input list. If textures are missing, the corresponding textures in the GBuffer are missing.

Parameters

from	source list

References WGEPostprocessor::m_depthTexture.

PostprocessorInput() [2/3]

WGEPostprocessor::PostprocessorInput::PostprocessorInput	(	osg::ref_ptr< osg::Texture2D >	color,
		osg::ref_ptr< osg::Texture2D >	normal,
		osg::ref_ptr< osg::Texture2D >	parameter,
		osg::ref_ptr< osg::Texture2D >	tangent,
		osg::ref_ptr< osg::Texture2D >	depth
	)

Construct GBuffer with an explicit list of textures.

Parameters

color	color texture
normal	normal texture
parameter	parameter texture
tangent	tangent texture
depth	depth texture

(

)

Constructor creates empty GBuffer.

All textures are un-initialized.
