Detailed Description

This class encapsulates an OSG Camera and a corresponding framebuffer object.

It is a specialized variant of WGEOffscreenRenderPass, optimized for processing textures. Therefore, it creates an correctly sized quad and can process each pixel in the fragment shader.

Constructor & Destructor Documentation

◆ WGEOffscreenTexturePass() [1/2]

WGEOffscreenTexturePass::WGEOffscreenTexturePass	(	size_t	textureWidth,
		size_t	textureHeight,
		int	num = `0`
	)

Creates a new offscreen rendering instance.

Parameters

textureWidth	the width of all the textures created and used by this render pass. This should be large enough for every reasonable viewport size.
textureHeight	the height of all the textures created and used by this render pass. This should be large enough for every reasonable viewport size.*
num	the order number. This camera gets rendered at the num'th place in the pre render queue of the subgraph it is attached to.

◆ WGEOffscreenTexturePass() [2/2]

WGEOffscreenTexturePass::WGEOffscreenTexturePass	(	size_t	textureWidth,
		size_t	textureHeight,
		osg::ref_ptr< WGETextureHud >	hud,
		std::string	name,
		int	num = `0`
	)

Creates a new offscreen rendering instance.

Parameters

textureWidth	the width of all the textures created and used by this render pass. This should be large enough for every reasonable viewport size.
textureHeight	the height of all the textures created and used by this render pass. This should be large enough for every reasonable viewport size.*
num	the order number. This camera gets rendered at the num'th place in the pre render queue of the subgraph it is attached to.
hud	the hud that gets notified about attached and detached textures. Useful for debugging.
name	the name of this render pass. This is a nice debugging feature in conjunction with WGETextureHud as it gets displayed there.
