A general purpose cave-like system for visualization of animated and 4D cad modeling

In the last decade, virtual reality (VR) systems have been used to enhance the visualization of CAD projects. The immersive VR techniques allow to the designer interacting and modeling in a more intuitive and efficient way. Current 4D and animated simulation CAD tools are a new challenge for immersive visualization. In this paper we propose a general purpose cave-like system that enables interactive visualization of 4D and animated CAD models. In an automated way, the system is able to treat static and dynamic 3D environments, allowing to share the experience of navigation in the scene among the users, even geographically distributed. The collaborative immersive multiprojection visualization approach has basically four modules for modeling, converting, visualizing and interacting. Besides the system had be designed and implemented for visualization of CAD models, it can be used for general purposes thanks to the use of a XML-based format on the visualization module. The system proposed is validated through a case-study using dynamic 3D models created on digital manufacturing softwares of Shipbuilding and Offshore Industries

ROS as a middleware to Internet of Things

This paper discusses the feasibility of using the framework Robot Operating System (ROS) as a basis for the development of a middleware in the Internet of Things (IoT) context. The main concepts regarding IoT and ROS are presented and followed by the evaluation criteria. Finally, case studies considering the ROS features and some common assumptions of IoT environments are analyzed

An immersive and collaborative visualization system for digital manufacturing

In this paper, an approach on immersive multiprojection visualization of manufacturing processes is proposed. It admits scenarios with dynamic components and allows virtual reality collaborative visualization among geographically distributed users through multi-CAVE devices. A set of modules for modeling, converting, visualizing, and interacting are also proposed. The method can be applied to CAD projects, models, and simulations used in industry. The ideas discussed are then validated through the study of a real case related to the shipbuilding and offshore industries
