We introduce QuadStack, a novel algorithm for volumetric data compression and direct
rendering. Our algorithm exploits the data redundancy often found in layered datasets which …

A novel multidimensional hashing scheme, named the Exclusive Grouped Spatial Hashing
(EGSH), which compresses repetitive spatial data into several compact tables while …

Abstract Multiresolution Hierarchies (MH) and Directed Acyclic Graphs (DAG) are two recent
approaches for the compression of high‐resolution shadow information. In this paper, we …

Computing accurate hard shadows is a difficult problem in interactive rendering. Previous
methods rely either on Shadow Maps or Shadow Volumes. Recently Partitioned Shadow …

Real-time rendering of pixel-accurate hard shadows in 3D scenes is still a challenging
problem for shadow generation techniques. In this paper, we present the concept of non …

Detailed shadows in large-scale environments are challenging. Our approach enables
efficient detailed shadow computations for static environments at a low memory cost. It …

Rendering soft shadows cast by dynamic objects in real time with few visual artifacts is
challenging to achieve. We introduce a new algorithm for local light sources that exhibits …

In this tutorial, we discuss voxel DAGs and multiresolution hierarchies, which are
representations that can encode large volumes of data very efficiently. Despite a significant …

Real-time shadow algorithms based on geometry generally produce high quality shadows.
Recent works have considerably improved their efficiency. However, scalability remains an …

Spatial encoding is an important technique for spatial binary data storage, which
differentiates the defined data from the undefined data in many computer graphics …
