Orthogonal unified buffer with memory efficiency

Abstract

In this paper, we introduce an Orthogonal Unified Buffer (OUB), which is an extension of the Layered Depth Cube (LDC) as an alternative to the Orthogonal Frame Buffer (OFB). Compared to the OFB, the OUB achieves significant improvement in memory efficiency, which enables a high-resolution representation of 3D models that have various depth-complexities. Similar to the OFB, the OUB resamples the surface nearly uniformly while conserving data locality. As a grid-based texture mapping method, the OUB shows satisfactory memory efficiency and is independent of an object's shape or topology. Our method is built and handled on the GPU, thus it is well suited for real-time rendering. © 2012 Springer Science+Business Media.
