This class enables you to add arbitrary nodes that get post-processed in screen space.
The only thing you need to take care of is your shader. You need some special parts in it. Please see the all-in-one super-shader-example module WMShaderExample in modules/template.

size_t | width = 2048 , |

size_t | height = 2048 , |

bool | noHud = false |

) |
Create a new post-processing node.
It uses the WGEOffscreenRenderNode to setup an offscreen, shader-based post-processing for rendered images. This is not limited to geometry but can also be used for ray-traced images.
reference | camera used as reference |
width | the width of the textures used in this rendering. Must be in [8,4096] and a power of two. |
height | the height of the textures used in this rendering. Must be in [8,4096] and a power of two. |
noHud | If true, no hud gets displayed showing the created and used textures. |

void WGEPostprocessingNode::insert | ( | osg::ref_ptr< osg::Node > | node, |
WGEShader::RefPtr | shader = NULL |
||
) |
Inserts a node to the post-processor and injects the needed code to the specified shader.
See class documentation for further details on how the shader gets modified. If you are using an group node, be yourself aware that all nodes in this group need to have the same shader! If not, post-processing will not work properly.
node | the node to post-process |
shader | the shader used for the node |
