The objective of the Project MANEUVER (Manufacturing Education Using Virtual Environment Resources)1 is to develop an affordable virtual reality (VR) framework to address the imminent demand for well-trained digital manufacturing (DM) professionals. One important part of Project MANEUVER involves studying, evaluating, and identifying cost-efficient ways to generate 3D solid models for use in VR frameworks. To this end, this paper explains the research effort to find alternative ways so that 3D solid model could easily be generated without using any costly 3D scanning technology. In this study, the project team identified two software tools that could help the manufacturing professionals and educators generate a solid model of several parts. These two software tools namely, Qlone and 3DF Zephyr Free were selected for this study based on factors such as ease-of-use, cost-effectiveness, and the cognitive load on users. Using case-studies these two software tools were used to generate 3D solid models and prototypes. Finally, their pros and cons collected throughout this study were reported.

A Systematic Analysis of Graphics-Based Hardware and Software for Virtual Reality Instructional Framework
This study explains in detail a review of the graphics-based Virtual Reality (VR) hardware and software that were evaluated systematically for use in the NSF-funded study (Project MANEUVER). Project MANEUVER (Manufacturing Education Using Virtual Environment Resources), is developing an affordable VR framework to address the imminent demand for well- trained digital manufacturing (DM) technicians. This paper explains the various important factors including instructional, graphics-based, immersive, and interactive aspects that need to be carefully considered in the decision making process for the NSF Maneuver project, and this can serve as a reference for other similar projects. 3D Virtual worlds can be visualized by means of an extensive array of interfaces such as CAVE (Computer Assisted Virtual Environments), desktop VR, HMD (Head Mounted Displays), etc. The other factors that are important especially from a graphics perspective include: Hardware (CPU) and graphics requirements, cost, standalone possibility, software compatibility/support.

There is an imminent need to remedy the ‘skills gaps’ in the digital manufacturing (DM) sector as evident from the Bureau of Labor Statistics projections pointing to a decline in traditional manufacturing jobs accompanied by marked growth in digital- and computer-driven manufacturing jobs. With proven advantages such as cost benefits, material conservation, minimized labor, and enhanced precision, manufacturing industries worldwide are adapting to digital manufacturing standards on a large scale. In an effort to remedy the lack of well-defined DM career pathways and instructional framework, our NSF ATE (Advanced Technological Education) project MANEUVER (Manufacturing Education Using Virtual Environment Resources) is developing an innovative pedagogical approach using virtual reality (VR). This multimodal VR framework DM instruction targeted at 2-year and 4-year manufacturing programs, facilitates the development of VR modules for multiple modes such as desktop VR, Augmented VR, and Immersive VR. The advantages of the virtual reality framework for digital manufacturing education include: significant cost reduction, reduction in equipment and maintenance costs, ability to pre-visualize the product before manufacturing. This paper introduces the design and development process of VR education tool to simulate three different additive manufacturing machines, e.g., LutzBot™, FormLabs™, and UPrint™ and different 3D printing technologies e.g., fused deposition modeling, and selective laser sintering to allow the students experience the materials and equipment needed to create the same part using different types of equipment and different types of technology.more » « less

We have developed a series of course-based undergraduate research experiences for students integrated into course curriculum centered around the use of 3D visualization and virtual reality for science visualization. One project involves the creation and use of a volumetric renderer for hyperstack images, paired with a biology project in confocal microscopy. Students have worked to develop and test VR enabled tools for confocal microscopy visualization across headset based and CAVE based VR platforms. Two applications of the tool are presented: a rendering of Drosophila primordial germ cells coupled with automated detection and counting, and a database in development of 3D renderings of pollen grains. Another project involves the development and testing of point cloud renderers. Student work has focused on performance testing and enhancement across a range of 2D and 3D hardware, including native Quest apps. Through the process of developing these tools, students are introduced to scientific visualization concepts, while gaining practical experience with programming, software engineering, graphics, shader programming, and cross-platform design.more » « less

This paper explains the design of a prototype desktop and augmented Virtual Reality (VR) framework as a medium to deliver instructional materials to the students in an introductory computer animation course. This framework was developed as part of a Teaching Innovation Grant to propose a cost-effective and innovative instructional frameworks to engage and stimulate students. Desktop-based virtual reality presents a 3-dimensional (3D) world using the display of a standard desktop computer available in most of the PC labs on campus. This is a required course at this university that has students not only from the primary department, but from other colleges/departments as well. Desktop VR has been chosen as a medium for this study due to the ease-of-access and affordability; this framework can be visualized and accessed with the available computers in PC labs available in university campuses. The proposed research is intended to serve as a low-cost framework that can be accessed by all students. The concepts of ‘computer graphics, modeling & animation’, instead of being presented using conventional methods such as notes or power point presentations, are presented in an interactive manner on a desktop display. This framework allows the users to interact with the objects on the display not only via the standard mouse and keyboard, but also using multiple forms of HCI such as Touchscreen, Touchpad, and 3D Mouse. Hence, the modules were developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this course titled ‘Introduction to Animation’. Finally, the framework has also been tested on a range of VR media to check its accessibility. On the whole, this proposed framework can be used to not only teach basic modeling and animation concepts such as spatial coordinates, coordinate systems, transformation, and parametric curves, but it is also used to teach basic graphics programming concepts. Hence, instead of a touchscreen, the modules have to be developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this animation course.more » « less

This Work-in-progress paper presents the pilot study of implementing a Virtual Reality (VR) environment to teach a junior-level Mechanical Engineering laboratory class at Prairie View A&M University. The target class is the manufacturing processes laboratory, which initially aimed to provide a hands-on experience with various manufacturing equipment. Providing students with systematic training followed by repetitive access to manufacturing equipment is required for longer knowledge retention and safety in laboratories. Yet, complications from the pandemic and other logistical events have negatively affected many universities' laboratory courses. The objective of this study is to examine the potential and effectiveness of the VR framework in engineering education. More specifically, this paper details the project's first phase, which includes the development and deployment of machining VR modules and preliminary outcomes. The VR module in this phase is based on the existing hammer fabrication project that requires the utilization of a milling machine, drill press, lathe, tap, and threading dies. A virtual replica of the machining laboratory was created using C# and the unity 3D game engine and published as an Android Package Kit (APK) for the META platform to be used in Oculus Quest 2 devices. The module is composed of three submodules, each corresponding to different hammer parts. These VR submodules replace traditional verbal and video training and are deployed in two semesters with 46 student participants. The student performance in project reports is compared with a control group for a quantitative assessment. Early conclusions indicate that the students remember the operation procedures and functions of equipment longer and are more confident in operating each manufacturing equipment leading to better quality parts and reports.more » « less
