Hi all,

using processing (alpha 68 ) I made an interactive 3D version of sodaconstructor. Here is the link:

http://www.sw3d.net

I released it just a week ago. I waited a bit before to post the link here just to monitor the site traffic.

Here is the link to my old post in the "introduction" thread of the alfha board:

Best Regards,
Marcello

Thank you v3ga

I think that it is possible to program an irregular  ground. But i should change the impact detection algorithm that, for now, is very simple (if z<0 then impact! ). Moreover i think that i should make some kind of ground generator.

Thank you Markavian

I was really amazed by the sw3d users. In few days they were able to make awesome models. Anyway they already are very good 2D constructors.

The mouse usage is a bit complex since there are a lot of things that it is possible to do with it. Moreover I had to maintain the classic sodaconstructor mouse usage during the construction of models so that new sw3d users can maintain their construction habits. Anyway i was care with the mouse programming. If you are rotating the camera view and accidentally you touch a mass, that mass will not be dragged on the screen and, viceversa, if you catch a free mass and drag it around the camera view will not change.

Yes, the reflection effect is cool and, also very very simple! It is enough to draw the model another time simply changing all the coordinate Z with -Z. It is also important to tone down colors.

Thank you mflux,

Ed Burton already know about sw3d in its Fortran version. After i tried to contact discreetly him but i hadn't answers so I'm not able to answer to your question.

Thank you very much Ed.

Anyway, to tell the truth, sw3d is just a little piece of your awesome sodaconstructor. Just a very little tribute to your original idea

Moreover I was able to program it also thanks to processing. Without processing i wouldn't be able to program sw3d.

Hi Marcello

Yes, probably you are right about the colors. I never have had a good taste for graphics. Nevertheless I got so used to it that i can't think to other colors.

I would prefer of not for many reasons. First of all is that in the code there are links to the php scripts that manage the sw3d user's accounts in my web site. I made that scripts thinking to the safety of the user's data like username, password etc etc. But i can't be sure that they are really sure. Some spiteful guy could do a lot of damage. The second reason is that i'm just an amateur, not a professional programmer; so my code is disorderly, confused, abounding and so on. The third reason is that it is so long! Sometime i think that it is a kind of miracle that it works

Anyway i'm disposed to talk with you about each aspect of the applet.  For example about the physics, the mathematics, or also other tecnical aspects like your following curiosity

I did in this way: when you catch a free mass with the mouse and you drag it around, the mass moves in a plane that is always parallel to the screen (i.e. orthogonal to the direction of the view). In this way you are moving the mass just in a plane but, when you'll change the angle of view and you'll catch the same mass, dragging the mouse you'll move the mass in another plane that is not parallel to the previous. Altogether you moved the free mass in a 3d environment. Have I made myself clear

Thank you very much

I didn't. I programmed by my own each object in that applet(*). I programmed classes for buttons, text window, scroll bar, etc

(*) I read again this statement of mine and I have to say that it isn't entirely true. I used the Glen Murphy's fast text class (I simply added other few fonts) and I used toxi's class about cylinders (for the muscle's visualization  no 4)
