Tiling Layered Depth Images
We present a system for modeling and real-time rendering of solid terrains. Using results from the field of tiling, we show how a global 3D texture can be computed for a 2D terrain using a small set of Layered Depth Images. We propose a new set of Wang tiles that are shown empirically to tile the plane without apparent periodic structure. Furthmore, we introduce a new imagebased data struture: ...
متن کاملRendering Layered Depth Images
In this paper we present an e cient image based rendering system that renders multiple frames per second on a PC. Our method performs warping from an intermediate representation called a layered depth image (LDI). An LDI is a view of the scene from a single input camera view, but with multiple pixels along each line of sight. When n input images are preprocessed to create a single LDI, the size...
متن کاملProgressive Visibility Caching for Fast Indirect Illumination
Rendering realistic images requires exploring the vast space of all possible paths that light can take between emitters and receivers. Thanks to the advances in rendering we can tackle this problem using different algorithms; but in general, we will likely be evaluating many expensive visibility queries. In this paper, we leverage the observation that certain kinds of visibility calculations do...
متن کاملMesh Generation from Layered Depth Images Using Isosurface Raycasting
This paper presents an approach for the fast generation of meshes from Layered Depth Images (LDI), a representation that is independent of the underlying data structure and widely used in image-based rendering. LDIs can be quickly generated from high-quality, yet computationally expensive isosurface raycasters that are available for a wide range of different types of data. We propose a fast tec...
متن کاملLayered Reflective Shadow Maps for Voxel-based Indirect Illumination
We introduce a novel voxel-based algorithm that interactively simulates both diffuse and glossy single-bounce indirect illumination. Our algorithm generates high quality images similar to the reference solution while using only a fraction of the memory of previous methods. The key idea in our work is to decouple occlusion data, stored in voxels, from lighting and geometric data, encoded in a ne...
