Abstract
We present a system for image-based modeling and rendering of real-world scenes containing reflective and glossy surfaces. Previous approaches to image-based rendering assume that the scene can be approximated by 3D proxies that enable view interpolation using traditional back-to-front or z-buffer compositing.
In this work, we show how these can be generalized to multiple layers that are combined in an additive fashion to model the reflection and transmission of light that occurs at specular surfaces such as glass and glossy materials. To simplify the analysis and rendering stages, we model the world using piecewise-planar layers combined using both additive and opaque mixing of light. We also introduce novel techniques for estimating multiple depths in the scene and separating the reflection and transmission components into different layers. We then use our system to model and render a variety of real-world scenes with reflections.
