We present an interactive algorithm to perform continuous collision detection between general deformable models using graphics processors (GPUs). We model the motion of each object in the environment as a continuous path ...

This paper presents an adaptive sampling method for image-based walkthrough. Our goal is to select minimal sets from the initially dense sampled data set, while guaranteeing a visual correct view from any position in any ...

Hybrid user interfaces (UIs) integrate well-known 2D user interface elements into the 3D virtual environment, and provide a familiar and portable interface across a variety of VR systems. However, their usability is often ...

A scalable distributed virtual environment (DVE) may be achieved by ensuring virtual world objects communicate their actions to only those objects that fall within their influence, reducing the need to send and process ...

In this paper, we propose a model to estimate the expected running time of hierarchical collision detection that utilizes AABB trees, which are a frequently used type of bounding volume (BV). We show that the average running ...

Even with today's highly sophisticated 3D modeling programs, creating, assembling and adapting 3D models is still a big challenge for inexperienced users. In this paper we present our approach of an intuitive table-top 3D ...

A huge variety of interaction techniques was developed in the field of virtual and augmented reality. Whereas techniques for object selection, manipulation, travel, and wayfinding were covered in existing taxonomies quite ...
