Force haptic reappearance technology is considered to be one of the top ten technologies that can change human life in the future. It has broad application prospects and market demand. Most of the existing medical robots, especially the remote diagnosis and treatment robots, lack haptic feedback, or the calculation of feedback force is insufficient. Haptic reappearance technology is an effective method to solve the problem of haptic presence and improve the practicability of medical robot.
The ultimate goal of the force haptic reappearance system is to let the operator feel the haptic feedback when interacting with the soft tissue model in the virtual environment in real time. Haptic device is the necessary condition to realize force haptic reappearance, and it is an essential part of the system. Its important role is to introduce the external force imposed by the operator into the virtual environment, and let the operator feel the force in the virtual environment, which effectively guarantees the operator's sense of reality and immersion when interacting with the virtual environment.
Therefore, starting with the key technology of force and haptic reappearance system, this paper studies the construction of force and haptic reappearance system. Soft tissue surface model is drawn by OpenGL, and hand model is drawn by 3Ds Max. The haptic reappearance and visual feedback of soft tissue model of hand palpation are realized. The quality of feedback is evaluated. The haptic reappearance is stable and realistic, and the visual feedback is smooth. This indicates that the system has a certain application value and is worth to promote to the public.
The research aims at benefiting from the technological development and the technical progress. This development necessitated that the educational process take advantage of this progress, and the ...development of special computer software, especially the design programs, made the two researchers think about how to benefit from these design programs in teaching students the skills of theatrical design. The current search aims at: Identifying the effect of 3Ds Max in developing the skill of theatrical decoration design among the students of the Department of Art Education "Third stage / Department of Art Education / Faculty of Fine Arts / University of Diyala for the academic year 2014-2015. The researchers used the experimental method of the two groups (controlling and experimental) and pretest and posttest method to achieve the objective of the research. The sample was selected from the students of the third stage / Department of Art Education for the academic year 2014/2015. The sample was randomized into two groups: the experimental group consisted of (15) students who studied through the use of 3Ds Max and the controlling group consisted of (15) students who studied in the traditional way. The researchers prepared a form for evaluating the skill performance of the theatrical decoration design. This form consisted of (10) paragraphs with a five-point scale and a percentage weight of five degrees. After preparing the research tool and achieving its validity and stability, the research was applied for eight weeks. The data attained were statistically processed and the results were reached at and the most notably effective of which was the 3Ds Max program in the development of the skill of the theatrical decoration design among students of the Department of Art Education.
In view of the problems of unintuitive operation and poor user experience in the human-computer interaction of smart homes, the article proposes the application of virtual reality technology on the ...basis of relevant theoretical analysis, based on unity development platform and smart home control center, a smart home control system based on virtual reality technology is designed and developed. The system is composed of client, cloud and device. The client realizes virtual roaming, real-time display of device status and remote control. The cloud realizes the functions of control command forwarding and data storage. The gateway is used to communicate with each home device and cloud to realize the functions of sending control commands and reporting device status data. The test shows that the system is novel and practical. Using virtual reality technology as a human-computer interaction interface for smart home control can give users an intuitive smart home control experience and improve the user's experience.
The purpose of this study was to explore the potential of capture systems in improving high school students' dancing skills through the use of experimental design. The major findings were as follows: ...First, using a MoCap system and high-speed camera to document dancers' movements can provide reference materials for students to improve their skills through self-practice. Second, using a MoCap system and high-speed camera as teaching aids at dance studio can enhance the effectiveness of dancing teaching. Third, incorporating MoCap and high-speed camera technologies into dance art is becoming necessary for achieving peak performance.
In this paper, we present the different modelling steps commonly used in car & motorcycle-body design along with our personal approaches on solving complex geometry and our own design iterations. ...This study offers an insight in how concept cars and motorcycles are modelled, how their different iterations are developed starting from the initial design and how to create a photorealistic render. The paper is presented in a step by step structure to aid future car designers in improving their workflow when using Autodesk 3Ds Max 2014 and achieving better presentation results using the VRay plug-in.

User interface similarity, 3D environment perception, adaptation and advantages are told in this study. The data in the study were obtained by the literature search and the lessons that researcher had with his students with observations, assessment of the situation and its results. In the end of the research shows us how already knowing 3Ds Max programme effects in learning and using Unity software.
Producing professional-quality 3D models is one of the main requirements in the work of architect. Behind photorealistic renderings lies the precise modeling of the building. The development of ...technology has led to the fact that today is very easy to get from 2D sketches to 3D models. That’s why it’s important to minimize the time required to finish this part of work and choose the right software for it. In architectural education in Serbia, the most used programs are AutoCAD and 3ds Max. Software as AutoCAD provide simple drawing of 2D plans of any object, while the realistic rendering can be easily obtained in 3ds Max. The question is which program to choose for the middle phase-creating a 3D model. In this paper we will compare the time needed for the same tasks as well as advantages and disadvantages of both programs. Based on the results, conclusions provide recommendations for the most effective solution: 2D drawing and modeling in AutoCAD, and rendering in 3ds Max.
