As radical and transformative technological revolution significantly changes the way of science and engineering practice, bringing these changes into engineering classroom becomes a need. This paper presents such a conduct that designs a virtual reality (VR) theme-based game system as a replacement of traditional laboratory activities in two fundamental electrical and computer engineering courses:...
In the world of simulation, Virtual reality (VR) software allows users to visualize, manipulate and interact with computers and complex data. VR has been utilized in applications such as architecture, medicine, advertisement, business, entertainment, and education. Developing VR environments is costly and expensive. Highly-technical persons are needed to create the virtual objects from scratch. Once...
Haptic interaction with the world is manipulation using our sense of touch. The term “haptics” arises from the Greek root haptikos, meaning “able to grasp or perceive.” Haptic interaction with computers implies the ability to use our natural sense of touch to feel and manipulate computed quantities. Haptic computer interaction is a relatively new field that has generated considerable interest over...
The true three-dimensional modeling is a common issue for geology, three-dimensional GIS, scientific is visualization and engineering application. This paper presented a new 3D data model that based on TEN, and introduced the TEN's generation algorithm and steps. The example indicated this algorithm can produce the tetrahedron unit mesh of the arbitrary shape three-dimensional geological body well.
This paper presents a solid blending method with up to curvature continuities. The method is based on the solution to a vector-valued sixth order partial differential equation containing three parametric variables subjected to solid blending boundary constraints. A simple and efficient method is developed to solve the partial differential equation. The shape of the created blending solids is manipulated...
