20 March 2009: Experiments with the wii and new parametresDesignTool

Posted by flemming Thu, March 26, 2009 17:18:12

Thanks to Marcin for his enthusiams and great effort regarding this experiment. The wii is working and new parametres has been added. A dynamic and generative system is defined by emerging 3d geometries which respond to speed. The size of geometry and the distance between the geometries reflects the speed of the movement of the hand with the wii remote. Furthermore at the same time the geometry can be affected by the movements of the hand by being repelled or attracted.

It has definitely improved the tool. I have been playing around. Its great. I will make a test printing with the sphere geometry and see if it has caused any problems. I send you an email when done.Blog image

I have tested the two new parametres "num sides" and "num segments", which seems to have great potentials. The test printing went very well without problems. Great!

26 January: New Version from MarcinDesignTool

I've added a checkbox to enable 'sphere generating mode' (enabled by default) and possibility of negative growing speed (shrinking). You have to decide what's better Wii or patterns how geometry emerges.

22 January 2009: Summary and further experimentsDesignTool

Posted by flemming Mon, January 26, 2009 12:56:12

By way of introduction I would like to ask you if following could be changed easily for testing 3d printing:
The geometry is now cubes. Is it possible to have the possibility to choose geometry such as spheres as well? Or simply just spheres? I think the expression will be more organic.
Can you invert the size from growing to reducing, but keep the possibility to choose maximum and minimum size? Can the minimum size be even smaller?

We have two overall issues:
1. Is it possible to develop the use of the wii as device before the deadline for paper submission or should we focus on the development of issue 2?
2. Improve the emerging geometry.
Issues about how the emerging geometry emerges and can be improved can be divided into two sections. One has to do with the geometry which is growing, here named A (that’s how it is in the latest version,) another (a new idea) has to do with the size of the geometry, which rely on the speed of the movement by the hand, here named B.
A:
You have talked about the possibility to somehow pull the geometry according to the movement relied on the speed, so the geometry will deform or extrude…it was quite interesting, - the expression will be more organic…can it be realized? I think I found a certain degree of that in the first version (2d) using balls and in the example figure 1 as well. Can the accelerator in the wii, be utilized regarding this issue?
I still think it is a good idea to test different patterns for how the geometry emerges such as in a spiral, double spiral or random. Right now the geometry emerges as a simple track similar to the movement. Can we have the possibility to choose between different patters?
Example figure 1: http://processing.org/learning/basics/storinginput.html

B:
This is another tool and maybe this one can be developed from A? In this tool the size of the emerging geometry relies on the speed of the movement of the hand such as in the example in figure 2? In this example it should not grow/reduce in size, but the tool should contain“behaviour” of the emerged geometry.
Example figure 2: http://processing.org/learning/topics/pattern.html and http://processing.org/learning/topics/pulses.html
Can the emerged geometry have a behaviour (unpredictable) with which we can interact?
Examples of behaviour can be:
1. http://www.ghostagency.net/processing/relations/index.html .
2. http://www.youtube.com/watch?v=a8inyyT53V4
Do you have any ideas?
How to interact?
The constellation with its behaviour could have a leader, which follow our position/cursor/origin. In that sense it is somehow a chain. The speed of the behaviour could change according our movement and become more or less lively. Geometry could be produced while pushing the mouse button and we could interact when not pushing?
Do you have any ideas for this issue?

A is more straight ahead I guess and a further development on the previous version. And maybe the one for further improvement right now, but if it is possible to mix ideas from B into it, it could be fun.
What do you think?

3. December: First test in 3d prints by a Stratasys, DimensionDesignTool

Posted by flemming Thu, December 04, 2008 23:03:46

This is really great. It is working perfect!

I have just tested it at the software at the 3d printer with no errors. To be sure I am going to make some small 3d prints over night.

3. December: New version from MarcinDesignTool

Posted by flemming Thu, December 04, 2008 22:55:52

Hi

Here is 3d in 2d version of drawing application. To export to .obj click 'save' on the right or press 's'. Currently there is no hidden surface removal implemented. Let me know if this works (3d and file saving).

26 November Question: A test for a 3d version?DesignTool

Posted by flemming Thu, December 04, 2008 22:54:09

Have you had time to make some further experiments with the wii and the possibility to change the 2d into 3d?

I think I have solved the problem about the hidden geometry, but it could be very useful to test it with a 3d obj. object from your programming. If "the wii issue" hasn't been solved yet, I wonder if it is possible to make some test just with the mouse as device but with 3d geometry, - or is it a long way round and in a wrong order?

But it could be very useful since I could start working on that issue already now.

----------------------------------------------------------------------------

Regarding upcoming parameters and modes I was wondering of the possibility of choosing in between and a combination of:

1. Making a track as we do in the present version and 2. The emitting modes:

A: the cubes emerge from origin but in a spiral pattern in the x-y plan.

B: like A, but with two spirals in opposite directions.

C: several of cubes emerge and grow from the origin in all direction (linear) at the same time in the x-y plan.

Regarding these modes, maybe some more complex pattern must be found instead, some which are based on 3d growing algorithms. Do you know anything about fractals? Does "processing" have any of these embedded for use?

13 November Test with the wii by MarcinDesignTool

Posted by flemming Tue, November 25, 2008 23:12:45

Today I started testing but I've destroyed 1.5 out of my 3 IR LEDs :/ I don't know WHY but they have reversed voltage inputs. So I have to go there and buy more LEDs (8dkk each). I totally forgotten that there is more 'pro' resolution to this problem 'Wii Wireless Sensor Bar' but it costs about 99dkk. I can start even with my current setup. Check out these photos:

10 November Question: 3d version and wii as device, or new modes?DesignTool

Posted by flemming Tue, November 25, 2008 23:08:56

I wonder if the further step, - dealing with a 3d virtual space and the use of the wii, - will make limitations or disable some of the existing or upcoming modes - or if it is easily converted?

So will the right step be to continue and add e.g. the emitter modes in this 2d version (and perhaps other modes) or will it be more rational to continue in a 3d version with the wii and the possibility to save an obj.?

In relation to the 3d printing it could be a good idea to test it soon as possible. The geometry might be very complex since it is produced by several of geometries e.g. a row of cubes. I guess this is a matter of how the obj.file is saved. E.g. if two or several geometries are overlapping, - will they be saved with all the hidden geometries or just by what's seen from the "outside"? The last version is to prefer...

If modes are easily added, I think of course it's great. But if it needs a lot of effort I suggest we take a break with further modes and concentrate on the 3d version with the possibility of saving an obj. and the use of the wii, - since that's a quite radical and important step. If we can't succeed in that, it will be a shame to have used a lot of energy in making further modes and parameters; - also I am just quite excited to test it for 3d printing.

What do you think?

(Following is just an idea of a mode I want to share:

1. If a geometry collides with another geometry, the collided geometry will change geometry e.g. from cube to sphere or opposite. Since the geometries are produced in a row and then would change immediately, I suggest following:

Geometries are produced in a row (when keeping down the mouse button), if paused a new row is produced. It is when geometries from two different "rows" collides they will change geometry.)

6. November Request From FlemmingDesignTool

Posted by flemming Tue, November 25, 2008 22:53:25

1. Parameter, which can control the speed of the growth of the geometry 2. Parameter, which can control the size (e.g. min/max in a range between 1-10?) of the geometry.

3. Parameter of a "wind/gravity force" left –right and up-down (e.g. min/max in a range between 1-10?) 4. Right now, - when pushing down the mouse button and the mouse kept in the same position- the geometry is growing stationary from the origin of the position. If possible following rules of the growing could be added as possibilities:

A: the cubes emerge from origin but in a spiral pattern in the x-y plan.

B: like A, but with two spirals in opposite directions.

C: several of cubes emerge and grow from the origin in all direction (linear) at the same time in the x-y plan.

5. Possibility to "freeze" the growing/movement at a mouse/wii button.
