  • 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 grant AllPermission to not extracted war file in tomcat

    - by André
    Hello, I'm developing a web application and have created a war file. If I deploy it to my tomcat server, it is used without being unpacked (which is the setting I want to have for this server). For unpacked web apps I have a policy file to grant AllPermission to my application grant codeBase "file:${catalina.base}/webapps/tc/-" { permission java.security.AllPermission; }; But what has the codeBase to be for unpacked war files? Thanks, André

  • What was your most useful/inspiring computer science course?

    - by MPelletier
    I'm currently taking one course per semester, remotely, in a short 5 year program. My aim is to get better at my trade (programming and analysis, not surprisingly). However, I find that I'm not inspired by my choice of classes for next semester. Maybe I'm being too judgmental. I'd like to know what positive experience was gained from a course in particular. Have ou had a course that turned out to be an idea catalyst?

  • iPhone SDK 3/4 App will not run on a iPhone 2.x device even with deployment target set to 2.0!

    - by MarqueIV
    Ok... I know about the difference between the base/active SDKs and the deployment target. I have my base SDK set at 4.0 and the deployment target set at 2.0. I am not using any APIs post 2.x, conditional or otherwise. Since I can't debug on a 2.x device, after building it, I use the iPhone Configuration Utility to install the app on the device, which it does just fine. Problem is, it doesn't run! I just get a blank screen. The main window never comes up! Now before you ask... I had this same problem with the iPhone SDK 3.x. I upgraded to the 4.x hoping it would be solved. It wasn't. Yes the provisioning profile is installed. (Couldn't install the app if it wasn't.) This same compiled app works fine on 3.x devices. Same with 4.x devices. Just not 2.x devices. Again, no I am not using any post-2.x SDKs. To prove this I created a brand-new, window-based app from the 'New Project' dialog and the only changes I made was the background color of the window (to prove the XIB loaded) and I set the deployment target to 2.0 (It's still compiled against the 4.x SDK though.) Again, it runs fine on 3.x or 4.x devices, but just a black, blank screen on 2.x devices. I've tried this on three separate 2.x devices included one freshly restored. I've used three separate dev machines (MacBook Pro with the 3.x SDK, MacBook Pro with the 4.x SDK and a Mac Pro with the 3.x SDK.) Same result every time. I am stumped. The fact that even an unmodified project doesn't run really has me confused. Could it be the XIB file? Did they change the format from 2.x to something newer in the 3.x SDK? If so, how do I set it back to 2.x. (Again, this is just a complete guess.) But I'm really stumped! Mark

  • Find who's calling the method

    - by Marcos Placona
    Hi, I'd like to somehow find out which CFC is calling my method. I have a logging CFC which is called by many different CFC's. On this logging CFC there's a need to store which CFC called for the log. Whilst I could simply pass the CFC name as an argument to my log.cfc, I find this to be a repetitive task, that might not be necessary, if I somehow could find out "who's" calling the method on log.cfc Is there any programmatic way of achieving this? Thanks in advance

  • .Net Library for parsing source code files?

    - by Jörg Battermann
    Does anyone know of a good .NET library that allows me to parse source code files, but not only .NET source code files (like java, perl, ruby, etc)? I need programmatic access to the contents of various source code files (e.g. class/method /parameter names, types, etc.). Has anyone come across something like this? I know within .NET it is reasonably possible and there are some libraries out there, but I need that to be abstracted to more types of programming languages.

  • Getting a Jabber status via Python

    - by Teegijee
    I'm developing a website using the Django framework, and I need to retrieve Jabber (okay, Google Talk) statuses for a user. Most of the Jabber python libraries seem like an incredible amount of overkill (and overhead) for a simple task. Is there any simple way to do this? I know very little about XMPP/Jabber, though of course I'm willing to learn. Do you need to be an authenticated and "friended" user to retrieve another user's status?

  • Ndepend CQL to find methods of certain types using particular framework assembly

    - by icelava
    In order to check if types not derived from certain base classes are using a low-level framework assembly, the following query can be used. SELECT TYPES WHERE IsDirectlyUsing "ASSEMBLY:Framework.Data" AND !(DeriveFrom "App.BaseTypes.BusinessFacadeBase" OR DeriveFrom "App.BaseTypes.BusinessComponentBase" OR DeriveFrom "App.BaseTypes.DataAccessComponentBase") Now I wish to drill down further to see which methods from those classes are actually doing so. But the thing is if I change the query target from TYPES to METHODS then DeriveFrom is not going to apply. How can these criteria be preserved?

  • Receiving data with Winsock

    - by Tamir
    Right now, I'm programming the networking for my online game, and I'm not really sure what to do about receiving data. The problem is that I can't really guess the packet's size, so I thought of reading just 4 bytes from the packet and converting them to an int to know what's the packet's size. Then I'll just create a buffer in that size and receive the rest of the packet, is that a good idea? For your information, I'm using non-blocking i/o.

  • Porting Windows socket program to Unix: Alternative for winsock32 APIs in unix

    - by Amita
    In Socket Programming, how will a Unix thread receive a Socket CLOSE event from a client if connection is closed? Are there any API's which will notify the unix thread about the CLOSE event received? As in Windows we have WSAEnumNetworkEvents API which gets the event notification for a specified socket descriptor. What will be the equivalent API used in the Unix socket programing? Please provide the help for the query.
