Signifier-Based Immersive and Interactive 3D Modeling

The Smart House Planner is an AI-powered solution designed to simplify the process of residential home design by combining intelligent planning, 3D modelling, and real-time cost estimation through an interactive conversational interface. With the rising demand for personalized housing solutions and the complexity of balancing aesthetics, functionality, and budget, there is a growing need for systems that can automate architectural planning while remaining user-friendly. This project addresses that challenge by integrating Gemini AI for intelligent design recommendations, Blender for automated 3D visualization, and a cost estimation engine for transparent financial planning. The system enables users to specify requirements such as housing type (1BHK, 2BHK, 3BHK, Duplex, Villa), dimensions, and style preferences via a modern Django-based web interface. Gemini AI processes these inputs to generate optimized layouts by considering space utilization, and functional flow. These layouts are then transformed into realistic, interactive 3D models using Blender, allowing users to explore their prospective homes virtually. Simultaneously, the cost estimation module calculates material, labour, costs, producing downloadable reports that support informed decision-making and budget control. By unifying AI-driven design intelligence, real-time 3D modelling, and detailed cost breakdowns, Smart House Planner provides a comprehensive platform that enhances user engagement, reduces reliance on professional intervention, and democratizes access to architectural planning. This solution demonstrates how AI, visualization technologies, and web-based interfaces can transform the way individuals approach housing design, making the process more efficient, transparent, and accessible to both professionals and non-experts.

Conventional interactive 3D tree modeling systems are generally based on 2D input devices, and it's not convenient to generate desired 3D tree shape from 2D inputs due to the complexity of 3D tree structures. In this paper, we present a system for modeling trees interactively using a 3D gesture-based VR platform. The system contains a head-mounted display (HMD) and a 6-DOF motion controller for interaction. We propose an improved procedural modeling method to generate trees faster for VR platform. Using the 6-DOF motion controller, users can manipulate tree structures by a set of 3D interactive operations, including geometric editing using 3D gestures, sketching, brushing and silhouette-guided growth. Our interactions are more flexible and convenient than using traditional 2D input devices, e.g., we allow the user to simultaneously rotate and translate parts of a tree using a 3D gesture.

In this paper we present a method for sharing interactive and dynamic 3D models that are collaboration-unaware, i.e., models that have not been designed to be used by multiple users at the same time. This functionality is an essential requirement for the inclusion of arbitrary 3D models, as generated by standard CAD or animation software, into teleconferencing sessions. A key aim of this work is to show that a large part of the required functionality can be developed in a way so that it is reusable for other applications such as shared whiteboards or networked computer games. Our method therefore consists of both an application dependent part that handles the specific tasks required for sharing 3D models, and of a number of generic services such as synchronization, scalable support for latecomers, and the ability to record and replay sessions. The generic services are based on an abstract media model and the RTP/I application level protocol for distributed interactive media. Any other application for a medium that shares this model and that uses RTP/I may reuse these generic services. We have implemented a prototype called TeCo3D demonstrating the feasibility of our approach.

In these days, 3D models are introduced as new digital contents such as video games and data material for 3D printer. The demand of 3D modeling for ordinary people has been increased. While using existed hand-held 3D modeling system, users have to estimate unmeasured area through a display. Also users have to terminate consequently modeling with watching a process of modeling [Fudono et al. 2005]. In this paper, we propose a novel modeling system which indicates route guidance by means of area limitation of modeling at the beginning. Owing to area limitation of modeling, users can obtain desired 3D model with watching effective route guide for measuring and automatic termination of modeling. Users can obtain desired 3D model easily and quickly

This paper mainly analyzes the application advantages of virtual reality technology in medical experiment teaching, and integrates the construction and structure of medical experiment teaching system. The application of virtual reality technology in medical experiment teaching can timely solve the problem of low simulation degree in clinical experiment teaching, and design a knowledge teaching system according to practical knowledge and theoretical knowledge. Experimental interactive model and 3d model system of virtual reality technology can improve the interaction of medical experiment learning and make students master the operation process of medical knowledge more easily. At the same time, using the virtual visualization function of virtual reality technology, medical experiment teaching can quickly simulate various organs of the human body and the diseased parts of patients, so as to provide students with fast surgery, which greatly realizes the development of intelligent operation of medical experiment teaching and builds a comprehensive medical experiment teaching model. Virtual reality technology provides strong technical support for the development of medical experiment teaching.

Utilizing the Fourth Dimension for Patient Education in Cardiovascular Surgery

We present MagicToon, an interactive modeling system with mobile augmented reality (AR) that allows children to build 3D cartoon scenes creatively from their own 2D cartoon drawings on paper. Our system consists of two major components: an automatic 2D-to-3D cartoon model creator and an interactive model editor to construct more complicated AR scenes. The model creator can generate textured 3D cartoon models according to 2D drawings automatically and overlay them on the real world, bringing life to flat cartoon drawings. With our interactive model editor, the user can perform several optional operations on 3D models such as copying and animating in AR context through a touchscreen of a handheld device. The user can also author more complicated AR scenes by placing multiple registered drawings simultaneously. The results of our user study have shown that our system is easier to use compared with traditional sketch-based modeling systems and can give more play to children's innovations compared with AR coloring books.

The development of 3D technology allows the digitisation of cultural heritage objects. Despite the fact that 3D scanning technology is not fully developed, it offers great opportunities for recording spatial data. Three-dimensional digital recording can be made for museum exhibits as well as for historic architectural objects. The method used is a non-invasive (non-contact) method, which is a significant advantage when working with historic buildings. The use of 3D scanners makes it possible to reduce the risk of damage to the monument. The application of a safe method of 3D scanning facilitates digital archiving of objects, which gives many possibilities of their use. One of them is digital dissemination of three-dimensional models and even making replicas using 3D printing technology. These types of models make it possible to reach a wide audience. First of all, they provide access to monuments for people with special needs, who currently constitute over a dozen percent of the population. In particular, they are the elderly, sick or people with various types of disabilities, e.g. motionally or visually impaired people. Literature analysis as well as conversations with dysfunctional people show that 3D digitisation of cultural heritage objects is needed and expected. The article presents an example of the use of modern 3D technologies for the dissemination of cultural heritage on the example of objects from the area of the Silk Road. A two-track process of making small museum artefacts available is presented. The first track concerns making objects available in the form of interactive digital 3D models placed on websites. The second one uses real models printed in 3D technology, which can be made available to visually impaired people. The work discusses the course of joint activities to prepare these 3D models and specialised activities that are necessary to make both versions of 3D models for presentation on the web and for kinaesthetic cognition, i.e. by touch. The authors’ actions resulted in the preparation of 3D models of historic vessels from the turn of the 11th/12th centuries from the ancient city of Afrasiyab – a suburb of modern Samarkand in Uzbekistan.

Insects are the most diverse group of living organisms on Earth, but their small size and structural complexity make species identification a challenging task, especially for those with less experience in entomology. Accurate identification is essential for pest management decisions in agriculture. Traditional 2D resources, such as field guides and taxonomic keys, may exhibit limitations when depicting complex insect structures, as exemplified by the intricate morphology of insect mouthparts. This study explores the use of 3D models to enhance the learning experience in insect identification and morphology education. We developed an online course that incorporated interactive digital 3D models alongside instructional videos and assessments. Participants (N = 102), primarily undergraduate students in natural sciences, completed pre- and posttests to assess knowledge gains. Additionally, they completed a survey designed to evaluate learning satisfaction, self-efficacy, limitations of the learning tools, and to collect open-ended written feedback. A paired samples t-test revealed a significant increase in posttest scores compared to pretest scores (t = −17.71, P < 0.001). Most participants rated learning satisfaction and self-efficacy above 9 on a 0 to 10-point Likert scale survey. Participants highlighted the effectiveness of 3D models in species differentiation and morphological understanding. Feedback suggested potential improvements, including expanded insect coverage and interactive comparison tools. This study demonstrates that 3D models can significantly enhance insect morphology education, providing an engaging and effective learning tool for students and pest management professionals.

A few 3D interactive modeling systems have been developed recently. Such systems must cope with a high flow of input measurements during the entire acquisition period. Therefore, the reconstruction and rendering algorithms used must all run online. However, compression algorithms are still run offline as postprocessing. In order to develop a fully interactive modeling framework, this paper presents an online compression algorithm where the system automatically adjusts the level of detail according to the user behavior. The proposed method can reduce peak memory consumption by more than 50% during the acquisition of a typical model and the final result is comparable to offline compression. Furthermore, the results obtained show that a local acquisition approach must be prioritized.

This chapter presents a method for archiving and searching three-dimensional Native American ceramic vessels using geometric modeling techniques. Archaeological vessels are scanned and defined as a set of 3D triangulated meshes composed of points, edges and triangles. Our work includes modeling the data with parametric surfaces, extracting features to raise the level of abstraction of data, and organizing vessel data based on XML schema. A visual query interface on the web was developed that permits users to sketch or select sample vessel shapes to augment text and metric search criteria to retrieve original and modeled data, and interactive 2D and 3D models.

In this three-year study, test scores for students taught veterinary obstetrics in a classroom setting with either traditional media (photographs, text, and two-dimensional graphical presentations) were compared with those for students taught by incorporating three-dimensional (3D) media (linear animations and interactive QuickTime Virtual Reality models) into the classroom lectures. Incorporation of the 3D animations and interactive models significantly increased students' scores on essay questions designed to assess their comprehension of the subject matter. This approach to education may help to better prepare students for dealing with obstetrical cases during their final clinical year and after graduation.

Using an Interactive 3D Model before Environmental Changes Take Place: Differences in Perceived Safety and Appeal Related to Cycling for Transport

User experience is one of the most significant factors that impact users’ opinions about products. This also applies to the user interfaces of household appliances. However, realistic interactive presentation of user interfaces of such appliances in a virtual form remotely over the Internet is challenging. In this paper, we present and compare two different methods of interactive presentation of an oven touchscreen control panel. The panel was precisely recreated as an interactive 3D model, reflecting both its appearance and functionality. The system allows users to interact with the control panel using a mobile device touchscreen or hand movements in a virtual reality environment. We describe an experiment aimed at evaluating and comparing different forms of interaction to determine the benefits and barriers to the presentation of complex products in a virtual form for marketing purposes.
