  • Fixing LOD gaps, T-junctions

    - by Jaka Jancar
    I'm creating a heightmap renderer. One of the examples for solving gaps when doing LOD I found is this: (from Game Programming Gems 2 - Greg Snook - Simplified Terrain using Interlocking Tiles) Wouldn't this still produce a gap, if the three vertices encircled with red were not co-linear? Shouldn't the middle triangle be split into two, as I marked with the orange line? Am I misunderstanding the problem, or is there a mistake in the example?

  • How to set subversion global-ignores to eliminate .metadata?

    - by FarmBoy
    I'm trying to set up Subversion on Ubuntu Linux. It seems to be working, except that when I made one change and tried svn status, I found about 100 files had been changed, in the .metadata directory. My ~/.subversion/config file currently contains the following line: global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ .*.swp .DS_Store What do I need to add to ignore the .metadata files? The directory under consideration is used by Eclipse for Python development using PyDev, if that matters.

  • Flex 3 ComboBox skin, limiting text width

    - by Rhys Causey
    I've created a ComboBox skin by extending mx.skins.ProgrammaticSkin. It's working fine, except I can't figure out how to limit the width of the text. Is there a way to control this within the skin? See the attached image for an example of the text going too far. I would like it to stop before the separator line to the left of the down arrow.

  • Accounting Style string format in ASP .NET

    - by Russ Bradberry
    I would like to know the easiest way to format a string as accounting style. I know how to format as currency using {0:c} but there are some differences in accounting style, for example, all the dollar signs will line up as well as all the decimal points, and negatives are expressed in parenthesis rather than with a "-" minus sign. You can find a good example of the way i would like it in excel if you format the cells as "accounting" with 2 decimal places. thanks in advance, russ

  • Cannot Install JDK

    - by Vince
    For the life of me, I can't install the JDK on Windows Vista. I keep getting the error, "This Software Has Already Been Installed on Your Computer. Would you like to reinstall it?" Problem is, it's evidently not on my computer, since I can't a) run Eclipse - I get "Could Not Find Java SE Runtime Environment" or b) Find any reference to Java from the command line when typing java -version - I get "Error opening registry key 'Registry/JavaSoft/Java Runtime Environment." Any ideas?

  • Unable to cast lists with Reflection in C#

    - by DrLazer
    I am having a lot of trouble with Reflection in C# at the moment. The app I am writing allows the user to modify the attributes of certain objects using a config file. I want to be able to save the object model (users project) to XML. The function below is called in the middle of a foreach loop, looping through a list of objects that contain all the other objects in the project within them. The idea is, that it works recursively to translate the object model into XML. Dont worry about the call to "Unreal" that just modifes the name of the objects slightly if they contain certain words. private void ReflectToXML(object anObject, XmlElement parentElement) { Type aType = anObject.GetType(); XmlElement anXmlElement = m_xml.CreateElement(Unreal(aType.Name)); parentElement.AppendChild(anXmlElement); PropertyInfo[] pinfos = aType.GetProperties(); //loop through this objects public attributes foreach (PropertyInfo aInfo in pinfos) { //if the attribute is a list Type propertyType = aInfo.PropertyType; if ((propertyType.IsGenericType)&&(propertyType.GetGenericTypeDefinition() == typeof(List<>))) { List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); foreach (object aListObject in listObjects) { ReflectToXML(aListObject, anXmlElement); } } //attribute is not a list else anXmlElement.SetAttribute(aInfo.Name, ""); } } If an object attributes are just strings then it should be writing them out as string attributes in the XML. If an objects attributes are lists, then it should recursively call "ReflectToXML" passing itself in as a parameter, thereby creating the nested structure I require that nicely reflect the object model in memory. The problem I have is with the line List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); The cast doesn't work and it just returns null. While debugging I changed the line to object temp = aInfo.GetValue(anObject,null); slapped a breakpoint on it to see what "GetValue" was returning. It returns a "Generic list of objects" Surely I should be able to cast that? The annoying thing is that temp becomes a generic list of objects but because i declared temp as a singular object, I can't loop through it because it has no Enumerator. How can I loop through a list of objects when I only have it as a propertyInfo of a class? I know at this point I will only be saving a list of empty strings out anyway, but thats fine. I would be happy to see the structure save out for now. Thanks in advance

  • Bash scripting know the result of a command.

    - by Fork
    Hi, I am writing a bash script to run an integration test of a tool I am writing. Basically I run the application with a set of inputs and compare the results with expected values using the diff command line tool. It's working, but I would like to enhance it by knowing the result of the diff command and print "SUCCESS" or "FAIL" depending on the result of the diff. How can I do it?

  • Android insertImage and the Gallery Application

    - by Steve Jones
    I am adding a bmp file to the media store using the line below ContentResolver cr = getContentResolver(); Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(cr, bmp, "name", "now")); I then go to the gallery application and it shows the image, but shows it under "Camera Pictures". Is there a way to change this to its own group, perhaps to its own group? Do I need a custom content provider for this? Thanks.

  • Dotted Border turns to solid if object is animated with jQuery.

    - by Serg Chernata
    I have a simple setup: an image and then a paragraph with a bit of info that is hidden and then slides up over the image on mouse hover. If I try to apply a border-top that is dashed or dotted onto the paragraph it simply turns into a solid line. Is this a known issue with a fix? I even tried adding the dotted border through jQuery and it still comes out as a solid line. <div class="wrap"> <img src="images/fillertxt.jpg" alt="image" /> <img src="images/filler.jpg" class="front" alt="image" /> <p class="info"> This is a short description with a bit of text. </p> </div> .wrap .info { width:204px; height:50px; background:url(images/infobg.jpg) repeat-x #8d9c0c; color:#f7f5ef; padding:3px; position:absolute; top:142px; left:0; border-top:3px dotted #8d9c0c; } $(document).ready(function(){ $("p.info").css("border-top","3px dotted #8d9c0c"); $(function(){ bindTypeOne(); $("input[type=radio]").click(function(){ if ($(this).attr("rel") == "type1"){ bindTypeOne(); } else if ($(this).attr("rel") == "type2"){ bindTypeTwo(); } }); }); function bindTypeOne() { $("div.wrap").hover(function(){ $(this).children("p.info").stop(); $(this).children(".front").stop().animate({"top":"141px"}, 400); },function(){ $(this).children("p.info").stop(); $(this).children(".front").stop().animate({"top":"0"}, 700); }); }; function bindTypeTwo() { $("div.wrap").hover(function(){ $(this).children(".front").stop(); $(this).children("p.info").stop().animate({"top":"80px","border-top":"3px dotted #8d9c0c"}, 400); },function(){ $(this).children(".front").stop(); $(this).children("p.info").stop().animate({"top":"142px"}, 700); }); }; });

  • Javascipt select a sentence in textarea

    - by John Adawan
    I'm thinking if there is a way to use javascript to pick up ANY ONE sentence from a textarea simply by clicking any position within that sentence. I'm thinking along the line of - first, get current cursor position (which I know how) - second, somehow locate the position of the previous fullstop and the next fullstop (how?) - take whatever content within the two fullstops. (how?) Or there is a simple way to do it?

  • Ruby concatenate strings and add spaces

    - by David Oneill
    I have 4 string variables name, quest, favorite_color, speed that might be empty. I want to concatenate them all together, putting spaces between those that aren't empty. So: name = 'Tim' quest = 'destroy' favorite_color = 'red' speed = 'fast' becomes 'Tim destroy red fast' and name = 'Steve' quest = '' favorite_color = '' speed = 'slow' becomes: 'Steve slow' (Notice: there is only 1 space between 'Steve' and 'slow') How do I do that (preferably in 1 line).

  • Prototype JS swallows errors in dom:loaded, and ajax callbacks?

    - by WishCow
    I can't figure out why prototype suppressess the error messages in the dom:loaded event, and in AJAX handlers. Given the following piece of HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Conforming XHTML 1.1 Template</title> <script type="text/javascript" src="prototype.js"></script> <script type="text/javascript"> document.observe('dom:loaded', function() { console.log('domready'); console.log(idontexist); }); </script> </head> <body> </body> </html> The domready event fires, I see the log in the console, but there is no indication of any errors whatsoever. If you move the console.log(idontexist); line out of the handler, you get the idontexist is not defined error in the console. I find it a little weird, that in other event handlers, like 'click', you get the error message, it seems that it's only the dom:loaded that has this problem. The same goes for AJAX handlers: new Ajax.Request('/', { method: 'get', onComplete: function(r) { console.log('xhr complete'); alert(youwontseeme); } }); You won't see any errors. This is with prototype.js 1.6.1, and I can't find any indication of this behavior in the docs, nor a way to enable error reporting in these handlers. I have tried stepping through the code with FireBug's debugger, and it seems to jump to a function on line 53 named K, when it encounters the missing variable in the dom:loaded handler: K: function(x) { return x } But how? Why? When? I can't see any try/catch block there, how does the program flow end up there? I know that I can make the errors visible by packing my dom:ready handler(s) in try/catch blocks, but that's not a very comfortable option. Same goes for registering a global onException handler for the AJAX calls. Why does it even suppress the errors? Did someone encounter this before?
