Real-time appearance preserving out-of-core rendering with shadows
Despite recent advances in finding efficient LOD-representations for gigantic 3D objects, rendering of complex, gigabyte-sized models and environments is still a challenging task, especially under real-time constraints and high demands on the visual accuracy. The two general approaches are using either a polygon- or a point-based representation for the simplified geometry. With the polygon-based approaches high frame rates can be achieved by sacrificing the exact appearance and thus the image quality. Point-based approaches on the other hand preserve higher image quality at the cost of higher primitive counts and therefore lower frame rates. In this paper we present a new hybrid point-polygon LOD algorithm for real-time rendering of complex models and environments including shadows. While rendering different LODs, we preserve the appearance of an object by using a novel error measure for simplification which allows us to steer the LOD generation in such a way that the geometric a...
