Three-dimensional (3D) visualization is the process of creating the three-dimensional object using a special computer program. Today computer graphics technologies such as 3D visualization technology are becoming more and more in demand. The technology has earned popularity among designers because it allows creating three-dimensional objects of any shape. It is widely used throughout the world to create the interiors of houses, offices, hotels, etc. This paper provides a brief introduction to 3D visualization.
Analysis of Systems for Development of 3D Models
International Journal of Academic Information Systems Research, 2021
The article initially discusses Maya and 3Ds Max because to some extent they are systems for developing threedimensional models. Further, most popular systems for development of three-dimensional models and analysis, engineering calculations were analyzed: SolidWorks, Ansys, Compass 3D, Autodesk Invertor and as result of analysis identified their advantages and disadvantages; application features. As result, 5 main indicators have been formed according to which it is necessary to choose system.

Nowadays, software development is evolving exponentially, with the hand of hardware and technological innovations. New languages or paradigms are required to provide solutions to those new technologies. This contributes to frequent changes in focus and as result of new areas of deployment,[Khaz00].
A software implementation of an interactive graphics system for three dimension modeling and layout
1986
: This thesis examines interactive techniques for viewing a 3-D building model in a walkthrough fashion and for placing 3-D piping into a 3-D building model. The focus of research is software implementation using the C programming language and the IRIS Graphics Library on the Silicon Graphics Inc. IRIS Turbo 2400 interactive graphics system. The first part of the research is concerned with drawing, viewing a 3-D building model, and examining interactive techniques required for building walkthrough mechanims. The second part is concerned with the development of techniques necessary to allow the placement of 3-D piping into a 3-D building model using 2-D graphics display and a mouse device. The algorithms and implementation of these techniques are presented.
AN INTERACTIVE ANALYSIS OF 3D TECHNOLOGY AND ITS VAST APPLICATION TO HUMAN
EPRA International Journal of Multidisciplinary Research (IJMR) -Peer Reviewed Journal , 2021
The word 3D is defined as three dimensional models that display a picture or item in a form that appears to be physically present with a designated structure. Three-dimensional (3D), can also describe any object that occurs on a three-axis Cartesian coordinate system, a Cartesian system is basically a fancy way of describing the X and Y axes which are horizontal and vertical axis, but the inclusive of the third axis Z which is make it to be 3D of which the Z axis represent the depth.3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in 3D space. The main features of these 3D applications are immersion, interactivity, and involvement. Immersion holds the user's attention. Interactivity is related to how responsive the application is to user actions and Involvement has to do with engaging the user's interest in the underlying activity.3D interaction techniques are selection and manipulation, navigation, system control and symbolic inputs. Its application is in the area of Exploring Complex Data, Visualizations with the Cubic Mouse, Multimodal Interfaces in VEs Multimodal interaction, and VEs for Design Education Architectural design.
Computer Peripheral Device for Modelling 3D Objects in a CAD Environment
IFAC Proceedings Volumes, 1997
The complexity of 3D-object design on a CAD workstation system is mainly due to the defInition of the coordinates that delimitate the object-space. The quantity of points dramatically grows with the required detail level of the object. The coordinates set may be defmed and adjusted point by point, to obtain a good quality design. This task is time consuming, thus expensive. The 3D graphic defInition is a hard job in which one of the most complex problems is the difficulty to represent the 3D workspace using only 2D devices (such as mouse, 2D screen, 2D scanner). The presently available specifIcation devices are either not easy to use or very expensive. The users generally work with conventional 2D devices, but it is necessary to emulate a 3D space. This abstraction overloads the application fIeld of each function which accordingly trends to become ambiguous. The proposal of this paper is to reduce the defInition time by proposing a device design that would be able to work as a 3D digital pointer, theBEE. The 3D pointer (BEE) is designed to provide, in a practical and easy to handle way, 3D coordinates to the workstation which will generate the computerized graphic defmition. The BEE allows the automatic capture of each object coordinate. Once the relevant points have been captured, the corresponding coordinates can be used to derive primitive objects (using lines, curves, arcs, planes, surfaces). Those primitive objects can then be used to form a complex object. The system uses the BEE as a kind of 3D mouse with the capacity to point at any point of the object space.
Virtual Inspector: a flexible visualizer for dense 3D scanned models
Computer Graphics and …, 2008
T he rapid evolution of automatic shape acquisition technologies will make a huge amount of sampled 3D data available in the near future. The cultural heritage domain is an ideal field for applying 3D scanning technologies (see the "Projects in 3D Scanning and Cultural Heritage" sidebar). Although these technologies still present some issues both in acquiring the 3D data (see the "3D Scanning Technical Issues" sidebar) and in their latter practical use, their potential impact in the cultural heritage field is clearly significant.
Interaction techniques for 3D modeling on large displays
2001
This article describes how virtual embossing and wood cutting can be done using the function representation of a shape and tools. The software is implemented as an interactive shape modeler where a functional model of the shape is subsequently modified with offset and set-theoretic operations. For visualization, interactive ray tracing is used. Bounding boxes together with the spatial organization of the functional model provide the required fast function evaluation that is usually a bottleneck for functionally based shape modeling systems. The software runs on a personal computer.
