I've worked on Airstage since its inception, contributing to research and development and the production of sharable demos in Unity.
As the project has grown I've streamlined multiple image matting techniques into a unified pipeline which greatly simplified writing shaders and creating new looks for users.
With our demos for Airstage we looked to show not only a range of possibilities for the toolkit in design but also in its aesthetics. I developed shaders for non-photorealistic effects like curved world perspective and toon lighting and more naturalistic effects like reflections based on 360 video in Unity's HD Render Pipeline.
