◆ create()

WGEPostprocessor::SPtr WGEPostprocessorMergeOp::create	(	osg::ref_ptr< WGEOffscreenRenderNode >	offscreen,
		const PostprocessorInput &	gbuffer
	)		const

virtual

Create instance.

Uses the protected constructor. Implement it if you derive from this class!

Parameters

offscreen	use this offscreen node to add your texture pass'
gbuffer	the input textures you should use

Returns: shared pointer to the created insteance

Implements WGEPostprocessor.

Here is the call graph for this function:

◆ setGLSLMergeCode()

void WGEPostprocessorMergeOp::setGLSLMergeCode ( std::string code )

Set the GLSL code inserted into the shader as merging operation.

If none was set, the mix command is used for each incoming texture. The code you write here should not make any assumptions to the environment it is inserted. What you have is a vec4 named color, initialized with vec4( 1.0 ). Set your final color to this vec4. It will be the result.

Parameters

code	the code as string
