Leonar3Do

Lore & Background

Daniel Rátai's childhood interest in spatial 3D drawing led him to develop the first edition of Leonar3Do, which won second prize in the National High School Competition in Innovation of 2004. In 2005, the Hungarian Association for Innovation asked him to represent Hungary at the Intel International Science and Engineering Fair, where the project earned multiple awards including the Intel Foundation Young Scientist Award and several special awards. That same year, he founded 3D For All Ltd., now Leonar3Do International Inc.

The Leonar3Do platform features a spatial input device called the 'bird' with six degrees of movement, 3D glasses with infra-LEDs, three tracking sensors placed on top of the display, and a central panel for bi-directional communication. The sensors track the position of the glasses and the bird, sending data to the central unit, which transmits it to the computer and system software to generate a complete 3D VR environment. The platform also includes a software development kit for creating new applications.

Patronage for the Leonar3Do education project was taken over by the Conference of Hungarian Rectors in December 2009, and the development team achieved their primary objective of turning the invention into a finished 3D VR product in 2010. In 2011, venture capital from PortfoLion enabled mass-production of the VR kit.

Reader's Guide

Leonar3Do represents a significant early effort to bring intuitive, desktop-based virtual reality creation tools to a broad audience. By replacing the traditional mouse with a six-degree-of-freedom spatial input device (the 'bird'), it allowed users to grab, move, and rotate 3D models in a natural manner, while the tracked 3D glasses provided immersive viewing from any angle. The platform's integrated hardware and software approach, including a complete SDK and plug-ins for Autodesk Maya and Unity, made it a versatile tool for education, design, and entertainment. Its educational variant, Vimensio, targeted primary through higher education, enabling users to create VR environments and simulations without programming. The platform's recognition at the Intel International Science and Engineering Fair and the Consumer Electronics Show highlighted its innovative impact. While not as widely adopted as later VR systems, Leonar3Do demonstrated early the potential of accessible VR creation tools and influenced subsequent developments in the field.
