Detailed description:

2D anti-aliasing post-processing filter.

This shader implements a 2D screen space anti-aliasing filter as a post-processing. It takes an input texture and return an anti-aliased version of that texture for all pixels in the image.

This shader can be used as rendering shader for a material assigned to a screen sized quadrilateral. If the quad's geometry is matching the input texture size - which is the usual way to use this shader - it performs a camera viewport sized anti-aliasing filter on the provided source .

The source image may be any 2D image. Linear filtering must be enabled on the image for the shader to produce anti-aliased results. See RED::IImage2D::SetFilterModes.

This shader uses the RED::MCL_VERTEX channel of the input geometry.

This shader has no indirect lighting configuration and only creates the RED::HW_GENERIC hardware configuration.

All parameters declared by this shader are using the RED_SHAD_TARGET_LIGHT_NO_LIGHT shader target (commonly used in its shortcut form RED_L0).

See the REDRenderShaderAAFilter.h file documentation for the list of all define statements used to name all parameters of this shader.
