New page

= Overview =

The image pipeline is LuxCore's built-in mini-compositor. 
It is plugin-based. The plugins are evaluated one after the other, each one taking the output of the previous plugin as its input.
The end result is available in form of the RGB(A)_IMAGEPIPLINE AOV.

= Available Plugins =

== Tonemappers ==

=== Linear Tonemapper ===

Simply multiplies all pixels in the image with the scale value.

=== Autolinear Tonemapper ===

Similar to the linear tonemapper, but estimates the average brightness in the scene to compute the scale value automatically.

=== Reinhard02 Tonemapper ===

An implementation of the reinhard tonemapper: http://www.cmap.polytechnique.fr/~peyre/cours/x2005signal/hdr_photographic.pdf

=== LuxLinear Tonemapper ===

Similar to the linear tonemapper, but the scale value is derived from ISO sensitivity, exposure time and aperture.
Can be used to match footage taken with a real camera.

== Effects ==

=== Camera Response Function ===

Simulates analog films.

=== Background Image ===

Shows the specified image on pixels that have alpha < 1. 
Note: When the size of the background image differs from the film size, it will be stretched to fit the film size.

=== Bloom ===

Blurs the input and blends the result over the input. 
Can be used to simulate real-world camera sensor imperfections.

=== Vignetting ===

Darkens the corners of the image. Used to simulate real-world camera lens imperfections.

=== Color Aberration ===

Creates color fringes on pixels with high contrast. The effect is stronger in the image corners. 
Used to simulate real-world camera lens imperfections.

=== Mist ===

Similar to simple OpenGL mist/fog. Uses the depth channel to fake mist. 
Should be used with a small amount setting to simulate aerial perspective on geometry that is far away from the camera. 
Note that since the depth channel is not anti-aliased, it will create jagged edges when the effect is too strong.

=== Contour lines ===

Creates contour lines for the IRRADIANCE AOV.

== Radiance Group (aka Light Group) ==

Shows only the contribution of lights with the ID of the radiance group.

= Special Plugins =

These plugins are for internal use by exporters/addons/plugins that use the LuxCore API.
The end-user will probably not come into contact with them.

== NOP ==

Does not modify the input, simply pipes it to the output.
Can be used to define an empty imagepipeline.

== Gamma Correction ==

Performs [https://en.wikipedia.org/wiki/Gamma_correction gamma correction].

== Gaussian Filter 3x3 ==

Blurs the image.

== Output Switcher ==

Can be used to get any film channel as input of the image pipeline, for example the MATERIAL_ID channel if you want to perform tonemapping steps on it.

= For Developers =

For details on how to define an imagepipeline with properties, see [[LuxCore_SDL_Reference_Manual_v2.0#Image_pipeline the SDL manual]].

== Creating new Plugins ==

Plugins are written in C++ and can optionally be accelerated with OpenCL.
