  • Getting normal information from OpenGL render output

    - by okamiueru
    I'll try to keep this simple. I want a way to access the normal information of the scene, from the Frame Buffer output (or similar). The same way one is able to access the Depth Buffer using glGetTexImage and GL_DEPTH_COMPONENT. I know I could set up a fragment shader which outputs the normal information in RGB color space, which could in turn be read from the rendered image. I'm wondering however if there is a way to do this within the openGL API. I'll clarify anything upon request as best as I can, Thank you

  • Getting the value from an array in the model in rails

    - by slythic
    Hi all, I have a relatively simple problem. I have a model named Item which I've added a status field. The status field will only have two options (Lost or Found). So I created the following array in my Item model: STATUS = [ [1, "Lost"], [2, "Found"]] In my form view I added the following code which works great: <%= collection_select :item, :status, Item::STATUS, :first, :last, {:include_blank => 'Select status'} %> This stores the numeric id (1 or 2) of the status in the database. However, in my show view I can't figure out how to convert from the numeric id (again, 1 or 2) to the text equivalent of Lost or Found. Any ideas on how to get this to work? Is there a better way to go about this? Many thanks, Tony

  • RequestFactoryEditorDriver getting edited data after flush

    - by Deanna
    Let me start with I have a solution, but I don't really think it is elegant. So, I am looking for a cleaner way to do this. I have an EntityProxy displayed in a view panel. The view panel is a RequestFactoryEditorDriver only using display mode. The user clicks on a data element and opens a popup editor to edit a data element of the EntityProxy with a few more bits of data than is displayed in the view panel. When the user saves the element I need the view panel to update the display. I ran into a problem because the RequestFactoryEditorDriver of the popup editor flow doesn't let you get to the edited data. The driver uses the passed in context and sends it to the server. The context returned out of flush only allows a Receiver even if you cast it to the type of context you stored in the editor driver in the edit() call. It doesn't appear to send and EntityProxyChanged event either, so I couldn't listen for that and update the display view. The solution I found was to change my domain object persist to return the newly saved entity. Then create the popup editor like this editor.getSaveButtonClickHandler().addClickHandler(createSaveHandler(driver, editor)); // initialize the Driver and edit the given text. driver.initialize(rf, editor); PlayerProfileCtx ctx = rf.playerProfile(); ctx.persist().using(playerProfile).with(driver.getPaths()) .to(new Receiver<PlayerProfileProxy>(){ @Override public void onSuccess(PlayerProfileProxy profile) { editor.hide(); playerProfile = profile; viewDriver.display(playerProfile); } }); driver.edit(playerProfile, ctx); editor.centerAndShow(); Then in the save handler I just fire the context I get from the flush. While this approach works, it doesn't seem right. It would seem I should subscribe to the entitychanged event in the display view and update the entity and the view from there. Also this approach saves the complete entity, not just the changed bits, which will increase bandwidth usage. What I would think should happen, is when you flush the entity it should 'optimistically' update the rf managed version of the entity and fire the entity proxy changed event. Only reverting the entity if something went wrong in the save. The actual save should only send the changed bits. In this way there isn't a need to refetch the whole entity and send that complete data over the wire twice. Is there a better solution?

  • Getting values from datagrid view column to list<>

    - by EvanRyan
    My main form in my application has a datagrid view that can have 1 to many user selected inputs. Column 8 of this grid is for the user to input "time in minutes." I have a separate class where I have built a timer that counts down from whatever time the user specifies down to 0. What I need is to create a series of alarms that go off as the timer counts down that are triggered by the user input values in column 8 of my datagrid. I think the best way to do this is to build a list< from the values in the datagrid. I for whatever reason can't quite figure out how to get the values from the datagrid in to a list< in my other class. Hopefully I explained in a way that makes sense.

  • HTML/JS/CSS issue getting bigger by itself

    - by Azzyh
    Here's the picture to begin with. I have this check box, that when you check, then with jQuery toggle(); it hides that you see in first half of the picture (#writeComment) and shows #SCtryVOTE (what you see in the other half picture, to the right). Now i dont know why but of some reason it expands when its checked, why i dont know, is it because it needs more place than it have or? how do i make this work without having problems when its checked. Here's coding: $('#tryout').click(function () { $('#writeComment').toggle(!$(this).attr('checked')); $('#SCtryVOTE').toggle($(this).attr('checked')); }); the js jquery script part, heres the table and divs HTML part: <input type="checkbox" id="tryout"> <table align="center" width="400" cellpadding="0" cellspacing="1" id="theBoxer"> <tr style="background: #686868;"> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> <td align="center" valign="top" width="70" height="25" style="border:1px #FFF solid;">Opret</td> </td> </tr> <tr> <td align="left" valign="top" width="70" height="112" style=""> TEST </td> <td align="left" valign="top" width="70" height="112" style=""> <div id="writeComment"> Smid en kommentar:<br> <form action="javascript:DoInsert()" method="post"> <textarea id="kommentar" name="kommentar"></textarea><br /> <input type="hidden" name="fID" id="fID" value="<? echo $_GET["id"]; ?>"> <input type="submit" name="Submit" value="Sæt ind!"> </form> </div> <div id="SCtryVOTE" style="display: none;"> <form onsubmit="if (!this.comment.cleared) clearContents( document.getElementById('comment') ); return true;" action="javascript:DoSCInsert()" method="post"> <textarea onfocus=" javascript:clearContents(this); this.cleared=true;" rows="5" cols="40" id="comment" name="comment" <?php if($vis["username"] == $pusername) { echo "DISABLED"; } ?>>Tryk for at skrive. Skal være detaljeret og grundet.</textarea> <br>Ja: <input type="radio" value="Y" id="SCvoteY" name="vote"></input> Nej: <input type="radio" id="SCvoteN" value="N" name="vote"> </input> <input type="submit" id="SCstem" name="Submit" value="Stem!"> </form> </div> Maybe you need the CSS part too for these two boxes: #writeComment{ position: relative; left: 5px; top: 10px; } #SCtryVOTE{ position: relative; left: 5px; top: 10px; }

  • Getting location via a web application being run in a WebView

    - by synic
    m.google.com somehow requests the current location when loaded in Android's browser. I want to do the same thing from a web page being loaded into a WebView in my own application. Is the only way to go about this with WebView.addJavascriptInterface(), or is there already a javascript interface available for webapps to use?

  • facebook api getting full posts with > 2 comments or > 4 likes

    - by ejang
    when I make the user/feed request on the Facebook Open Graph API, I get a feed object where posts with 2 comments or 4 likes don't reveal the detailed information for those specific comments. I am using https://github.com/Thuzi/facebook-node-sdk to make requests but it is very similar to the 'request' NodeJS library. I can get the full posts individually by making a separate request for that post's Open Graph ID, but this doesn't lend itself to fun code because requests are asynchronous and nesting more asynchronous calls within asynchronous calls doesn't lend itself to fun code. Any way I can obtain the full posts?

  • Getting the most frequent items without counting every item

    - by DeadMonkeyWalkin
    Hi. I was wondering if there was an algorithm for counting "most frequent items" without having to keep a count of each item? For example, let's say I was a search engine and wanted to keep track of the 10 most popular searches. What I don't want to do is keep a counter of every query since there could be too many queries for me to count (and most them will be singletons). Is there a simple algorithm for this? Maybe something that is probabilistic? Thanks!

  • Getting a particular menu item from MainMenu

    - by Garry
    I have a nib (winA.xib) that contains a window. My app delegate contains an NSWindowController subclass called WinAController. WinAController has a property (NSMenu *mainMenu) that I want to point to the MainMenu. I have set it after I instantiate WinAController with this code: WinAController = [[WinAController alloc] initWithWindowNibName:@"WinA"]; WinAController.mainMenu = [NSApp mainMenu]; I have a menu item underneath the "Window" top-level menu item on MainMenu that invokes the [WinAController showWindow] method and displays WinA. I want to toggle the on/off state of this menu item depending on whether WinA is visible or not. WinAController also has another property (NSMenuItem *myMenuItem). How can I get a reference to a sub menu of the "Window" top-level menu item. The title of sub menu item I want to get is "Command". I have tried this: if (mainMenu != nil) { myMenuItem = [mainMenu itemAtIndex:[mainMenu indexOfItemWithTitle:@"Command"]]; } But it doesn't seem to work. Where am I going wrong? Thanks,

  • DotNetOpenAuth getting return_To url as the provider

    - by Jeff
    I have a provider that I'm upgrading from version 2 to version 3. basically a user comes to one of our sites and we say "if you don't have an openID sign up with this one" They click that and are sent to our in house provider what signs them up for an account and has to verify their email address. In the link I send via Email I included the return to url . This way when they click the link to verify their email (sometimes up to a week later) they are sent to our page that knows to send them back to the returnTo to login. I could not find a good way to do this in version 2 so I used a hack. Sadly this hack broke in version 2 so I'm completely stumped as to how to find the login page url that is the return_To Note: I need the full URL not just the domain. old hack: if (ProviderEndpoint.PendingAuthenticationRequest != null) { req = ProviderEndpoint.PendingAuthenticationRequest.ToString(); int startpos = req.LastIndexOf("CheckIdRequest.ReturnTo = '"); startpos += "CheckIdRequest.ReturnTo = '".Length; int endpos = req.LastIndexOf("token=") - startpos-1; if (endpos > 0) { req = req.Substring(startpos, endpos); } else { log.Fatal("Missing token in url" + ProviderEndpoint.PendingAuthenticationRequest.ToString()); return "~/"; } req = req.Replace("&internalLogin=True", ""); req = req.Replace("?internalLogin=True&", "?"); req = req.Replace("?internalLogin=True", ""); }

  • Django Getting RequestContext in custom tag

    - by greggory.hz
    I'm trying to create a custom tag. Inside this custom tag, I want to be able to have some logic that checks if the user is logged in, and then have the tag rendered accordingly. This is what I have: class UserActionNode(template.Node): def __init__(self): pass def render(self, context): if context.user.is_authenticated(): return render_to_string('layout_elements/sign_in_register.html'); else: return render_to_string('layout_elements/logout_settings.html'); def user_actions(parser, test): return UserActionNode() register.tag('user_actions', user_actions) When I run this, I get this error: Caught AttributeError while rendering: 'Context' object has no attribute 'user' The view that renders this looks like this: return render_to_response('start/home.html', {}, context_instance=RequestContext(request)) Why doesn't the tag get a RequestContext object instead of the Context object? How can I get the tag to receive the RequestContext instead of the Context? EDIT: Whether or not it's possible to get a RequestContext inside a custom tag, I'd still be interested to know the "correct" or best way to determine a user's authentication state from within the custom tag. If that's not possible, then perhaps that kind of logic belongs elsewhere? Where?

  • Rails - Paperclip, getting width and height of image in model

    - by Corey Tenold
    Trying to get the width and height of the uploaded image while still in the model on the initial save. Any way to do this? Here's the snippet of code I've been testing with from my model. Of course it fails on "instance.photo_width". has_attached_file :photo, :styles => { :original => "634x471>", :thumb => Proc.new { |instance| ratio = instance.photo_width/instance.photo_height min_width = 142 min_height = 119 if ratio > 1 final_height = min_height final_width = final_height * ratio else final_width = min_width final_height = final_width * ratio end "#{final_width}x#{final_height}" } }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":attachment/:id/:style.:extension", :bucket => 'foo_bucket' So I'm basically trying to do this to get a custom thumbnail width and height based on the initial image dimensions. Any ideas?

  • Why is my emit not getting called?

  • Mac OS X: getting names of changed/written files

    - by Patrick
    I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

  • GKSession sendDataToAllPeers getting invalid parameter

    - by cb4
    This is my first post and I wanted to start it by thanking the many stackoverflow contributors who will never know how much they helped me out these past several days as I worked to complete my first iOS app. I am indebted to them and to this site for giving them a place to post. To 'pay off' some of that debt, I hope this will help others as I have been helped... So, my app uses the GKPeerPickerController to make a connection to a 2nd device. Once connected, the devices can send text messages to each other. The receiving peer has the message displayed in a UIAlertView. Everything was working fine. Then I decided to experiment with locations and added code to get the current location. I convert it into latitude & longitude in degrees, minutes, and seconds and put them into one NSString. I added a button to my storyboard called 'Send Location' which, when tapped, sends the location to the connected peer. This is where I ran into the problem. Both the send text and send location methods call the sendPacket method with a NSString. sendPacket converts the string to NSData and calls sendDataToAllPeers. When I learned how to capture the error, it was "Invalid parameter for - sendDataToAllPeers:withDataMode:error:". [.....pause.....] Well, this was going to be a question but in writing all this to explain the problem, the answer just dawned on me. Did a few tests and verified it now works. The issue was not in sendDataToAllPeers, it was in the conversion of the NSString (strToSend) to NSData: packet = [strToSend dataUsingEncoding:NSASCIIStringEncoding]; Specifically, it was the degree sign character (little circle, ASCII 176). NSASCIIStringEncoding only includes ASCII characters up to 127 so don't use any above that. I'm sure there was a quicker way to find the problem, but I don't know Objective-C or Xcode's debugging facility well enough yet. Whew! Several hours to discover that little tidbit. I did learn a lot, though, and that's always a good thing!
