摘要：The application of virtual reality technology has become more and more influential in garden design. Quest3D as a significant software to realize the virtual reality technology is utilized in this study to make a garden roaming demonstration system with the gardening design of a classical courtyard as an example. Besides, the advantages and disadvantages of applying Quest3D technology in garden landscape design are elaborated from the perspective of the selection of Quest3D technology, basic procedures for the selection and establishment of software and hardware.

摘要：Recently, virtual reality and interactive somatosensory technology has become one of the hot issues in the research of computer applications. Leap Motion is a new type of interactive somatosensory devices which bring users senses of immersion efficiently. This paper studies a interactive somatosensory game model based on Leap Motion and implemented with Unity. Based on the two core technology philosophy of Leap Motion, i.e., virtual reality technology and body sense of interactive technology, the design implementation of each sub module of the system and Leap Motion game algorithm are thoroughly addressed. This paper has certain significance for future application of Leap Motion in film, television, and interactive games.
