How does the Leonar3Do work?
The main components of the Leonar3Do interactive desktop VR (virtual reality) hardware are: a spatial input device (the 'bird') with six degrees of freedom, 3D glasses and monitor-mounted sensors. The bird operates in six degrees of freedom, which means that you can not only move the individual objects or the whole space, but also rotate them. The 3D glasses allow users to perceive a stereoscopic image displayed before the monitor area as three-dimensional object. The sensors continuously track the position of both the bird and the glasses, and send information through the central unit to the Leonar3Do system software. The applications generate, manage and display the virtual reality created in accordance with the data processed.
What kind of camera is used for position detection?
Leonar3Do does not use cameras. To achieve sufficient precision, resolution, reliability, speed, and low production cost, in other words to be able to offer a reasonable price for a wide range of end-users, we had to go beyond the limitations of camera-based solutions. Brand new, unique, patented solutions were developed that are based on infra red detection.
What is the purpose of detecting the position of eye-glasses?
By detecting the position of eye-glasses, it is possible to project the two different pictures for each eye, precisely according to the actual position of our eyes. This results in a strikingly realistic illusion of space. If we look at an object from the right or from the left, we actually see them from the right or from the left if we head the object it feels really the same, as if we actually headed it. Besides the experience itself, it has absolute importance concerning Leonar3Do, since this is how we can correctly interact with virtual reality. In other words, precise visualization is indispensable if the tip of the bird should touch the virtual object exactly at the point we intend to touch it.
What kind of monitor is required for Leonar3Do?
Active eye-glasses were developed for Leonar3Do, whose flickering effects are much lower than the common shutter-glasses have at the same monitor frequency. Thanks to this and several other solutions to be patented Leonar3Do offers the first solution, which is able to provide good quality three-dimensional images even on traditional TFT monitors. Use a monitor with at least 75 Hz frequency. At 75 Hz the image still vibrates, but its quality is acceptable. The less common 85 Hz TFT monitors cost about the same, the image is of good quality and the flickering is hardly sensible. Using 120 Hz TFT monitors there is no sensible flickering effect. 120Hz TFT monitor is recommended
What kind of software can be found in the Leonar3Do package?
The following in-house developed software set is found on the Leonar3Do DVD:
- LeoWorld: LeoWorld is a unique 3D VR modelling and animation software. You can easily control the software thanks to its simple and intuitive user interface. The real-time polygon optimization lets you easily shape any form with a speed never experienced before, color in 3D, change the lighting in real time, give physical attributes to virtual objects (changeable mass, gravity, impectability, rebounding etc.), create 3D animations, and export them into a video format. You can even create the game world of your own using reserved and free-formed objects, and do thousands of things previously only be dreamt of in science fiction films...
- LeoBrush: The monitor here represents a canvas (2D), for which you can use the bird as an air-brush (3D). Everyone has an artist inside, you just have to find the appropriate tool to express yourself.
- LeoGomoku: Alias spatial Noughts and Crosses or Amoeba. In the VR version of the popular logic game, you can test your combination skills on four levels of difficulty. Do not despond if you loose as early as the first stage against the heartless machine, sooner or later you will succeed. If not, you can also choose to play with a mortal opponent.
- LeoBang: A dozen of different virtual levels are waiting for you to knock down the blocks displayed.
How can Leonar3Do be used together with 3D CAD programs? Leonar3Do package include the LeoWorld program. LeoWorld supports standard three-dimensional file formats (.obj, .stl, .3ds) so it is compatible with any 3D design software.
Is it possible to develop software for Leonar3Do?
Yes, after a registration on the Leonar3Do’s website (www.Leonar3Do.com) the SDK will be available for anyone, which allows the easy development or adaptation of any software to the Leonar3Do platform.
