Multi-touch table using LLP - 60" 16:9 HD

The Multi-touch table is the result of a special course at DTU Informatics, Technical University of Denmark. For details about the method and the technology behind it, see the NUI Group website: http://nuigroup.com/

Demo: PyMT http://pymt.txzone.net/

i love the 1337 on the calc.

@stockbogger Finally! I was waiting for someone to comment on that :)

[jonidimo]

great explain. but I want to know how to make that screen panel. Do you put a paper on the acrylic panel so the projector can show the image? what kind of acrylic panel do you recomend? or it is a some kind of film like displax?How exactly are you dispersing the laser evenly on the surface?Where did you get the laser?

[edvaldig]

@jonidimo Sorry for the late response :) If I remember correctly it's a rosco 25% white diffusion film. We were lucky and got it from leftovers. This is a 10mm Plexiglas panel, which can easily handle pressure like small children stomping on it :) The lasers include a prism which creates a laser plane out of the beam. The lasers must be focued properly to make the laser plane as thin as possible. The lasers also include a faint red light visible to the eyes so they are easy to adjust by hand.

@hadesBEL Just to add, the fractal implementation is a part of the pymt framework (pymt.eu)... I can´t seem to give you any links through this commenting systemn but you can find the fractal implementation at their github under examples/apps/mandelbrot

[edvaldig]

@catndog52 It already is :) You can now easily implement your own starting at nuigroup.com

@hadesBEL It´s not a rasterized image but a generated one. you can easily implement an "endless" recursive fractal visualization using shaders, I found one example for you but can´t seem to paste it here for some stupid reason :) try googling fast and easy shader fractals

das ist der hammer

@grimjack2600 thank you, I know that web, but I just want to know what do you use to the projection screen.

@jonidimo check out nuigroup.com. Lots of great information on how to build these.
