Controlling desktop blender with N900 accelerometers - maemo.org

int_ua | # 1 | 2010-09-09, 06:39 | Report

Both Blender and Maemo have python.
So it is potentially possible and potentially not so hard to make N900 3d blender controller.
All we need is python modules for:
0. Recording accelerometers data on N900;
1. Streaming accelerometers data live to desktop and caching it real-time;
2. Controlling active blender view;

I suppose it will be:
a) active only when holding some button (camera for example), and
b) turning blender view relative, not absolute.

Great idea!

From your description you just want to control the scene camera, but you could also use it for tracking when recording video with the n900 camera.

But even if you wanted to use a more advanced camera and use tracking, you could literally strap the n900 to a video camera. If you had the clocks synced on both.

To be honest, I don't get it yet.

please explain more

What data can be synced with video this way?

What`s the pratical use of this? I mean, I`m not complaining, I`m just asking.
Like, could we use pc mouse via acc control ( example )? Or maybe play a game?

Edit : And oh, for the guys who knows about this, and will port it, the source codes are avaible to download in the link given before.

First of all I want to control 3d view of Blender (in edit mode, not in games or videos). I think it would be much more comfortable then with mouse or numpad.

Is it's URL http://www.aktasway.com/blog/2009/06.../blender95.rar ?
I can't download it:

Here is quick reference for controlling 3d view with Python:

Oh, well, sorry, I didn`t click the link in that post cause for me the source wouldn`t be of much use, and I didn`t check it was dead. Anyway, it seems to be a nice app, and as I am right now developing something personal, I might still be able to test it when you guys release it. =)

First working code that controls one boolean value of 3d view with python (for Blender 2.54):

Code:

import bpy

def test():
    areas = bpy.context.screen.areas
    for area in areas:
        if area.type == 'VIEW_3D':
            area.active_space.show_floor=not(area.active_space.show_floor)
test()

using two links:
http://www.blender.org/documentation...aceView3D.html
http://blenderartists.org/forum/showthread.php?t=193207

Update: rotating camera (not view yet but object named so):

Code:

area.active_space.camera.rotation_euler.rotate(0.2,'X')

It was easy:

Now the only thing that left is translating raw accelerometer data in blender moves...
