Hey guys,

Is there a program on processing out there to create a 3D figure of an aircraft? My current code works with a cube but i wish it to be a plane instead. Any idea how to do this please?

Thanks

Hey everyone,

Im working with an arduino 1280 which is connected serially via USB to 6 sensors (3 accelerometers and 3 gyros) and i wish to display their data on a real-time graph on processing.

How can i do this please as ive never done it before?

Thanks in advance

 

THIS IS A REPLY TO MY PREVIOUS QUESTION.

For some reason i cant reply or comment to my own question, anyway, yes, everything is sent serially via USB.

This is my processing code, if you need my arduino code i'd be happy to provide it too. Thanks in advance :)

Hey guys,

im having problems finishing off my project and i could really do with some help.

I have created a 3D box to represent my physical hardware. I have a 6DOF connected to an arduino. This 6DOF contains 3 accelerometers and 3 gyros. My problem is that my z axis just doesnt want to work well, that is, when i move my 6DOF left and right, nothing happens, whilst my pitch and roll (x and y axis) works fine. I think the problem's coming from my processing code not my arduino code, but im not sure.

Can anybody help me out please as i cant seem to find the problem?

Thanks in advance.
