dynamic picture

Hello. I need show object position  in a 2D indicator. 

I have a background , an object and  3 datas (x,y,z) for position  you can see in attachment. 

I want this: when x,y,z values sum are not equal 0 (-x+x, -y+y, -z+z) my object changing position.

You can think x and z values like angle (if x sum >0 => z sum<0). 

Is my prolem clear and Can anyone help me.

Thanks.

Hi keremgeliz,

you need to draw your picture with the coordinates you calculate from your xyz values. When those values change you draw that image again…

You can get this cheaper by putting your bg as decoration in the background and using your "object" to customize a boolean button with. Then all you need to do is setting the position of that button using its properties…

Hi GerdW Thanks for your interest. Now i create a vi (on attachment) But still have big problems. 

I cant use 3 coordinates in a 2D indicator. But i think its not problem for me because x = - z 

Now i dont know how can i change x (angle) position in picture indicator.

So i need  your help still.

Best Regards

Hi kerim,

a small solution using some basic math (and complex numbers):

As I said before: calculate the coordinates of your "object" and draw it in a 2D picture indicator…

Hi GerdW,

Now i am using your draws for my background but I have to use my original object (its cannot drawable with LV). 

So that i need change my object angle with "draw unflatten pixmap.vi" i think but different data types with complex data (in my attachment)

Or i need otherwise (i dont know how).

Best Regards.

Hi Kerem,

you cannot rotate your image like that.

The point array is generated just for the DrawPoints function I used in my example!

But there are several threads in the forum that discuss how to rotate image data. Do a little search…
