Leonar3Do

Leonar3Do is an integrated software and hardware platform, which is capable of creating an entire three-dimensional virtual reality environment. It enables the transformation of the traditional configuration of desktop computers (or other devices) into an interactive complete three-dimensional work environment. By using this virtual reality kit, creation, manipulation and analysis of three-dimensional objects are feasible in a real three-dimensional space. The solutions, products, and applications based on Leonar3Do platform are developed and marketed by Leonar3Do International Inc. (founded by the inventor of Leonar3Do, Daniel Rátai, Budapest, Hungary).

About the technology and structure

Leonar3Do has the following main hardware components:

The so-called "bird", which is the spatial input device. This device replaces the traditional mouse, which was originally

developed for the 2D flat dimension of desktop computers. The bird has six degrees of freedom; thanks to this feature, the user of Leonar3Do can not only grab and move the entire space or the object but rotation is also possible.

Three-dimensional glasses with built-in infra LEDs which enables the detection of the eyeglasses’ position.
The three sensors which should be placed on the top of the display.
The central panel which enables the bi-directional communication.

The three sensors' task is to track the position of both the 3D glasses and the input device (bird) and send this information to the central unit. The central unit transmits the received data to the computer and the Leonar3Do system software which generates, manages and displays the virtual reality environment produced in accordance with the data processed. The result is a complete 3D virtual reality environment. The user perceives the virtual object from any angle, as if it were real. Leonar3Do also has a complete software development kit, which allows the development, in the generally known programming language, of new applications, based on the Leonar3Do platform. By Leonar3Do's modeling software, users can give physical attributes to virtual objects like changeable mass, gravity, impeccability, and rebounding.^[1]^[2]^[3]^[4]

Products and industrial solutions

Vimensio: This solution was also built on the Leonar3Do platform, and its main target is primary, secondary, and higher education.

By using Vimensio, users can create

virtual reality environments, simulations or develop new 3D VR (virtual reality) applications for effective studying. Vimensio contains the above mentioned Leonar3Do hardware elements and the Vimensio educational software.

Vimensio Edit: Gives users the ability to create their own three-dimensional educational applications, without the usage of programming languages.

Vimensio Play: A cross-platform application system which allows the presentation of the already created three-dimensional content.

Leonar3Do for 3D Designers and Artists: It offers an interactive and intuitive way of 3D VR modeling. This solution contains the LeoWorld, and the LeoBrush software (details below); also, an Autodesk Maya plug-in has been already developed for the Leonar3Do platform. Small changes can be carried out more precisely by manipulating the vertex, polygon, and face surfaces. The so-called BOX MODELING character building is also feasible in the spatial space. The hardware kit is also included.
Leopoly: Leopoly was also built on the Leonar3Do platform, and its main target is online co-creation, sculpting and sharing 3D models.

Software applications

Software applications require a 3D monitor and a Leonar3Do Professional Edition Kit or a Vimensio Kit, including the Leonar3Do system software and the hardware elements.

LeoWorld: A 3D VR (virtual reality) animation and modeling software. It enables real time polygon optimisation, lightning modification, and 3D coloring. The software forms the geometry of the object in real-time as the polygons are rearranged. Users can also give physical attributes to the 3D virtual objects like changeable mass, gravity, impeccability, and rebounding.
LeoCapture: With the help of this software, the 3D VR work process, which has been carried out by the user, can be captured in 3D, and represented (even in real-time) in the flat 2D environment without a 3D camera and 3D player. The software creates the accurate video clips with the help of a traditional web camera.
LeoConf Software: LeoConf is the multi-user version of Leonar3Do. This means that the picture which is displayed by any Leonar3Do application, is also can be projected in real time to the audience. LeoConf is suitable to create 3D demonstrations or presentations for masses of people, just like in a 3D cinema.^[5]
LeoBrush: LeoBrush is-an air-brush simulator software. The software application transforms the monitor into a canvas, and the bird can be used as a 3D air-brush. The user can save the completed creation in various file types.
LeoGomoku: This is the 3D virtual reality version of the so-called "Tic Tac Toe" game.
SDK Software: Application development software, which enables the development of new, Leonar3Do-based software in a C++ or OpenGL working environment. It includes the application programming surface, the sample files, the source code, and one year of developer support.
Autodesk Maya plug-in: Leonar3Do International has developed a 3D plug-in for the Autodesk Maya software. The plug-in allows the viewing of the processing objects in real time 3D without rendering. Subtle changes can be carried out precisely by manipulating the vertex, polygon, and face surfaces. The so-called BOX MODELING character building is also feasible in the spatial space.
Unity game engine plug-in: The plug-in for Unity game engine, allows the user to develop a unique 3D VR game.
Vimensio software: The Vimensio software has been developed for educational use. It has the aforementioned Leonar3Do features. In addition, it has an integrated application builder software, with which the users are able to create their own educational content. Vimensio also offers built-in, preconstructed educational content. With the help of this software, teaching, studying, and demonstrating is made possible in a 3D virtual reality environment.^[6]

History of Leonar3Do

Even in his childhood, Daniel Rátai was already interested in the construction of spatial 3D drawing. He wanted to break with the 2D drawing and modeling method in which all designing methods are rooted. This motivation has led to the creation of the first edition of Leonar3Do, which won him the second prize of National High School Competition in Innovation (2004). In 2005, the Hungarian Association for Innovation asked Daniel to represent Hungary at the final of Intel International Science and Engineering Fair (Intel ISEF) (May 2005, Arizona, PX).^[8]^[9] Daniel Rátai and the Leonar3Do project was awarded six first prizes at the fair (details below). In the same year Daniel founded 3D For All Ltd. (the present Leonar3Do International Inc.) as a family business. The development team and the entire company succeeded by 2010 to turn Daniel Rátai's invention into a finished 3D virtual reality product.^[10] In 2011, venture capital was invested into the business by PortfoLion, enabling the company to make further developments and to start the mass-production of Leonar3Do virtual reality kit.
