Plot cylinder from the equation (and a trajectory on it)

Hello,
for an application I need to plot a cylinder. I already found the "Create Cylinder" + "Create Object" combination for displaying a "ScenObject", but I am not sure it is the best vi I need (I also did not understand if I need 2 objects in order to use the Object.AddObjectNode, but this is a differente story).
From an external application I get the 'a' and 'b' paramenters of the cylinder equation (X^2 / a^2) + (Y^2 / b^2) = 1, and I need to plot the cylinder starting from these parameters. Is it possible with labview?
Moreover, once the cylinder is plotted, I should draw on its surface a trajectory: t is a sort of 'Z' trajectory that starts from a point, goes parallel to the major axis for a certain length, than starts from the first quote, but offsetted by a certaing quote along the minor axis. So the final result is a series of parallel line on a portion of the cylinder surface.
Can you please help me figuring out a solution?
thank you a lot in advance and best regards,
Diego

It will cost you approximately US$219.00 to US$299.00 depending on the model.

    Hello there,
    Is there a way to open Excell file from the server and display in the UI and save it back on to the server? (like showing xell file as a datagrid - add rows, columns etc.)

  • We purchased a new iPad2 and registered it using a 'new' iCloud email/ID. We are unable to send email from the iPad and iPhone. The error is: Cannot send mail. The user name or password for iCloud is incorrect.

    We purchased a new iPad2 and registered it using a 'new' iCloud email/ID. We are unable to send email from the iPad and iPhone. The error is:>> Cannot send mail. The user name or password for iCloud is incorrect.

    About ~20 hours later, this ended up solving itself. We can send email using the '.icloud' email from both the iPad and iPhone.  Advise would be 'wait' before you start seeking alteranatives like yahoo, hotmail, etc.  This definitely is a convenient way to keep all your 'cloud' information in a centralized place, including the common email...

  • My phone will randomly disconnect from the wifi and when I retype the password it says it is wrong. It will eventually work but I have to wait for a message to pop up on my screen to allow me to retype the wifi password.

    When I first got my phone it worked perfectly fine with the wifi. Although later on I began to have problems connecting it. It will randomly disconnect from the wifi and when I try to retype the password it tells me it is wrong, although it is right. It will eventually work but in its own time, a message will pop up and allow me to type in the password and it will work. But sometimes it takes an hour or more and sometime it takes 10 minutes. I've seen where other people have had this problem but I don't know how to fix it. I'm not sure if it's an issue with my phone or if it's with my wifi. Does anyone know how to fix this?

    Does this happen with all Wi-Fi hotspots?  A specific one?
    Have you tried forgetting the Wi-Fi connection and then reconnecting to it?
    What about power cycling the Wi-Fi router?

  • Need help Take out the null values from the ResultSet and Create a XML file

    hi,
    I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
    a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
    takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
    from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
    null values to XML File. When i run the program it works alright and adds the null and not null values to
    the file. But when i pass the boolean value to take out the null values it would not take it out and adds
    the null and not null values.
    Please look at the code i am posing. I am showing step by step where its not adding the null values.
    Any help is always appreciated.
    Thanks in advance.

  • Delete record from the form and from the database

    hi,
    i want delete record from the form and the database ,but the record is only delete from the from !!!
    this is my code :
    if //condition then
    delete_record;
    commit;
    end if ;
    Any solutions ??
    thnx

    You have unique key field(s) on the table you are trying to insert which actually restricts you from inserting the same value again.
    When you are deleting the record and issue commit there is a record to be inserted in the table which is a duplicate that's why you are getting this unique error.
    As oracle is not able to insert your commit fails and stops your deletion of record from table

  • Can I use two Time Capsules? one as an extension of my laptop (for music and video storage) and the other one to back up everything from the laptop and  Time Capsule (for music and videos)

    Can I use two Time Capsules? one as an extension of my laptop (for music and video storage) and the other one to back up everything from the laptop and  Time Capsule (for music and videos)

    Not via Time Machine.   It cannot back up from a network location.
    The 3rd-party apps CarbonCopyCloner and ChronoSync may be workable alternatives.
    EDIT:  And, if you're going to do that, you could back up from the Time Capsule to a USB drive connected to the TC's USB port.  Second TC not required.

  • My iTunes says I owe $5.25 for songs that I have already paid for and am not going to pay for again but I want to get some apps from the store and now there's a hold on my account. Who do I talk to get the hold taken off

    I explained it most in my question but I am getting charged double for songs that I have already paid for and am not going to pay for twice because that is messed up. But I want to get some apps from the store and it wont let me because of $5.25. Who can I talk to about resolving this issue?

    You're right, it would have been covered under warranty. But because of the user damage, chances are there's a 200-something dollar fee . If you explain to them that it had a defect previously, they might replace it for you at no charge. **MIGHT**. But they would have to believe that it had a defect previously.

  • I have uploaded photos from the past and they are grouped by dates.  How do I seperate those photos into their own folder/album so that I can easily identify the contents.  Also, what is the difference between Album, Smart Album and folders?

    I have uploaded photos from the past and they are automatically arranged by date.  As a result, there are many events grouped into one library/event/folder/album (not sure of the proper terminology) I'd like to separate them into folders/albums/smart albums so that I can easily identify the contents.  How do I do that and do I delete the originals?

    It would be good to take the tutorials and learn iPhoto - these are for the previous version but the concepts are the same and much of the command is the same - and it would be a worthwhile investment of time to take the iphoto tutorials - http://www.apple.com/findouthow/photos/ - they are very helpful and will save you a lot of time and frustration. - also the tutorials in iPhoto Help will be helpful - while iPhoto is easy and intuitive it does have a learning curve and it will save you time and pain if you spend a few minutes learning the basics
    as to organization - events are generally time based and are the basic automatic organization - you can merge and split them to make them work better for you but they are not a good way to do detailed organization - best to leave them time based
    albums are logical things that contain photos and are just pointers to the photo in the event so they take no extra space and all changes to a photo anywhere are reflected everywhere
    Smart albums are the same except they are automatically filled based on the criteria you set when you create them
    Folders are containers that you create and a folder can contain albums, smart albums or other folders so they are a big help in organization - like a vacation folder that holds folders for France, USA, China with each of thos folders holding albums of photos from the country
