New Post-Processing Stages

This project aims to equip the post-processing pipeline with a good amount of new artistic effects, to allow users to tweak the overall look and feel of their scenes without having to leave appleseed.

The four main effects which will be added are Bloom, Tonemapping, Chromatic Aberration and Vignetting, which do not take place during rendering, but rather, are composited on top of the resulting image.

Post-processing applies full image filters and transformations to the rendered scenes, which can drastically improve their visual quality with little computation time. Currently, this is only possible with final renders in appleseed, however, bringing this feature to paused interactive renders is another goal of this project, as this is a more artist friendly approach to testing different customizable values of effects.
