(a) (b) (c) (d) Figure 1: Basic object manipulation techniques such as translation (a) and rotation (b) are illustrated in long exposure photographs. Augmentation can be projector-based (a-c) or via video-see-through (d). These application examples show basic augmentations of building structures (a,b,d), distance measurements (c) and material-color(More)
In situ visualization has become a popular method for avoiding the slowest component of many visualization pipelines: reading data from disk. Most previous in situ work has focused on achieving visualization scalability on par with simulation codes, or on the data movement concerns that become prevalent at extreme scales. In this work, we consider in situ(More)

In this work we present the ZAPP, a management framework for distributed visualization systems. The main purpose of ZAPP is to improve the user, administrator, and developer experience in dealing with distributed displays. Even a single user with no administrative knowledge can operate a ZAPP-managed display system. The goal is that practically anyone is(More)
This paper presents the design and implementation of a GPU-based ray tracing system for dynamic scenes consisting of a set of individual, non-deformable objects. The triangles of each object are organized in a separate Kd-tree. A bounding volume hierarchy (BVH) is built on top of these Kd-trees. The BVH is updated and uploaded into GPU memory on a(More)
