How to generate random curves under image control?

Hello

I'm still in the learning process LV my current objective is to have a circle drawn in the image optimization to move everything in the path of a curved line. The problem is that whenever I run the VI a new different trajectory is programatically created for my circle.

I don't know how to approach this problem.

A similar VI, I had the balls moving linearly, so I simply added a speed component to the component of the position of my balls. I initially use the same design here, but I can't devise a set of rules that would make the change in the result of the position on a trajectory of curved line. I think that generate a picture of the whole trajectory before each execution would probably work here, but I can't think a function do it either. Play with basic trig led sinusiodal or curved trajectory, but nothing really random out of period and amplitude.

Ideally, I want as much possible variance in the path (ex: a function that could give me S, U-shaped, in the shape of spiral, loop, etc.) while maintaining control of certain parameters (length, position, max dX, etc..)

Someone has an idea?

Thank you!

Looks like a random Walker.  One that I just did.  At each time point (0.1 seconds in this example), he took of the unit step in one direction, with the changing direction by a random amount within an angular range.  It can get pretty wild...

    You set only randomChar once. You would need to change this quickly on the key.

  • How can I determine the position of the mouse in a 2D image control

    I have an app where I would like the user to be able to interact with objects in a 2D image control with the mouse.  To do this, I need to translate between the screen coordinates, which are transmitted with the events of mouse and in the control of 2D image.

    The problem that I am running is that I can't find a way to determine the screen coordinates of the top left corner of the drawing/client of the 2D image control area.  I tried to use the 'Position' of the image control property, but this results in a mismatch because of the difference between the upper-left corner of the image control (including the label, etc.) and the upper left corner of the drawing area.  See attached VI.

    Does anyone know how to get the coordinate of the screen from the corner of the drawing of the control of the photo area?

    Mark Moss

    I tend to use the mouse in the image control property to get the position.  Deals with things like the passage of origin for you.

  • Creating a statue in gold that will generate random passwords for each deployment and how to recover passwords

    Hello

    New to 5.5 VDC and I hope that it is easy for you all the gurus.  After you create a statue in gold to say windows 2008 server and presentation in the public catalog how configure you to generate passwords random administrator when visitors in each of the ORG VDC wants to use it.  Now, I know you sysprep the OS in advance, and then when it starts, you can run the configuration wizard, or you can even define an answer file for things like the password key and administrator of the permit but y at - there a better way?  Having to go through the console and through a cloud of today technologies Assistant seems a bit old fashioned for me so I'm hoping its just something I missed narrowly in the configurations.

    The goal is simple... a customer deploys a VM and when it starts it is all ready to go so that no 2 VM This statue gold doesn't have the same credentials.  Somehow, they are provided with a generated random password to access the start new systems.  Amazon AWS for this using the keys if you deploy a virtual computer, you don't get invited to set a password... instead you can use your portal and get the password generated for you.  Their VM deployment and are ready to go without any additional configuration steps from the user at all.  How this is possible on a Director vcloud solution (or even at all).  I would like my customers to deploy from model, receive or access their new password and ready to go.  There may be a way to query the DB somehow and pull the password in this way?  And while I'm focused on windows operating system at the present time, it would be very happy to be able to do the same for root users on UNIX based as well as models.  Many big public cloud providers can provide their customers with this so I know there is a way but many also use things like openstack cloudstack or not vcloud Director.  Also I'm not familiar with the scripts so if you can get this kind of solution using scripts I'd appreciate some information or links that may describe step by step how to achieve and I will be happy to learn.  Thanks in advance

    UNIX systems are supposed to work.  And I know most the time they do.  (IE Redhat / Cent seems to work very well, however I have seen a few posts on this forum where a specific verion distribution may not work correctly.)

    Where to find the password.  Once the virtual machine boots (if the option to customize comments has been set at random) - the password will be on screen customization of comments; beside the selection of radio "Random."

    The API also has a way to get the password in case you need to expose in a different method.  (You can get it from section guestCustomize to a virtual computer in the restAPI thus).

    You can try the below code snippet:

    ResourceRepository rrepo = new ResourceDBRepository();
    Resource = rrepo.findResource (resourceName);

  • How can I programmatically draw new circles on an image control

    Hi, I'm fairly new LV and programming in general. I'm creating a program to get better. In this program, I have balls bouncing around on an image control. I use a table to keep track of the ball position (x, y) and the other to follow their speed. I want that whenever a ball reaches the border of the image, it splits into 2 balls. My problem is that I can't find a way to programmatically add these new balls for each draw circle screw must be serialy connected and then drawn on the image. What Miss me?

    You need to iterate over your table of bullets.  This means that the use of automatic indexation.  Now, you have no reason of wire with a value of N in the loop For.  And wiring of this value to the array Index function gives you invalid data it's either nothing, or the ball even if it exists in the table.

    I cleaned up a few other things in your code.

    1 cancel the function.  No need to multiply by-1.

    An array of Index 2.  It is expandable.  Drag the bottom border down.

    Your next bit of code to add would be where you decide to add another ball and put it in the Position and speed tables.

  • How could I possibly remove the default image in the image control?

    I use the image control and a bit of code to create a zoom on a picture effect. Everything works fine however I get a picture of labview when the Vi is loaded for the first time. I'm trying to get a blank area instead cause it looks like not really tidy!

    I have attached a picture and my code.

    Thanks for your help

    The image is configured to be the default value of "Photo". In other words: you must get rid of the default value. You can do this either by:

    (a) 'Image' of delete and recreate. Disadvantage: You have to re-create all the nodes property associated with this control.

    (b) load an image empty and select "data operations > use current default value.

    hope this helps,

  • change the border color of an image control

    Hi all

    I shows 30 photos on the façade by using an image control. I want the user to select 12 peaks of 30 photos.

    is there an interactive way to show what image has been selected. I thought that it would be OK to change the color of the border of the control.

    I would like to know how to change the border color of th and you are really welcome if you have a better way to say what peak has been selected.

    Thank you

    Ritesh

    Hi Ritesh,

    in my LV7.1 installation I could change bordercolor using the tool to color in development mode, but I couldn't find a property to change the colors by programming...

    So my advice would be to put a little bigger Boolean flags (or color boxes) behind the indicators of the photo. When the image is clicked/selected just change you the color of the underlying Boolean value. In this way imitate you the colorchanging of an indicator of the photo border...
