Light Paths Visualization and Viewport Unification

Light path recording is a unique and potentially extremely valuable tool in appleseed; however, it is currently relatively limited in capability of both data capture and visualization. This project aims to help remedy both of these by improving the number of quantities that are able to be recorded, improve the visualization capabilities for these quantities, and provide a method for basic data analysis, filtering, and report generation.

In order to do this, a main piece of the project will be to provide a unified viewport in appleseed.studio which is capable of displaying and switching between several possible views of a scene and overlay data and widgets on top of it. This will greatly improve the usability of appleseed.studio as a scene mastering tool by allowing a technical artist to view exactly how different parts of a render are being affected by lights, objects, etc. and will pave the way for even more useful data integration to be added in the future.
