Due to emerging new technologies in the development of interactive 3D applications (eg games and virtual reality), stereoscopic visualization is becoming a common feature. However, this fact does not solve some problems (nausea and headaches -cybersickness) related with the generation of this type of visualization. Some parameters have to be carefully chosen to create a comfortable stereo view, for example, eye distance, zero parallax plane distance, and the treatment of partially clipped objects in negative parallax. This paper presents a technique based on a CubeMap structure to dynamically adjust stereo parameters during the usage of two virtual reality tools in multi-scale 3D scenarios.
Navigation in virtual 3D environments, especially those with multiscale features, is still a problem for many users. In this regard, a good design of the navigation interfaces is critical to ensure that the users navigate with the best possible efficiency and comfort. In this paper, we present improvements made to two well-known interfaces: fly, including support to collision treatment and automatic navigation speed adjustment in relation to scale, and examine, with automatic pivot point. Such techniques are based on the cubemap structure. Usability tests have shown a significant improvement in the execution of navigation tasks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
