Aggressive Visibility for Rendering Extremely Complex Foliage Scenes

Daniel Cohen-Or ? Erez Sayer ? Alan Lerner ? Yiorgos Chrysanthou ? Oliver Deussen

Abstract:

This paper introduces a method to accelerate the rendering of extremely complex scenes by representing large portions of the scene with simplified representations. The method uses aggressive visibility to tag large and mostly occluded portions of the scene as background. The background scene is rendered by low cost imposters. The method masks any parallax errors that might be introduced by the imposters by ensuring that the foreground geometry is dense enough in image space, so that the background image is merely visible through small and sparse holes. We apply our method on large and complex scenes with moderate density, such as foliage scenes, consisting of a huge number of small disconnected pieces. We show that the presented method accelerates the rendering of such scenes while maintaining high visual fidelity and suppressing the parallax error.
