  • Move the location of the XYZ pivot point on a mesh in UDK

    - by WebDevHobo
    When working with any mesh, you get an XYZ point somewhere on it. If you just want to move the mesh in any direction, it doesn't matter where this point is located. However, I want to rotate a door. This requires the point of rotation to be very specific. I can't find anywhere how to change the location of the point. Can anyone help? EDIT:

  • Resolving a collision between point and moving line

    - by Conundrumer
    I am designing a 2d physics engine that uses Verlet integration for moving points (velocities mentioned below can be derived), constraints to represent moving line segments, and continuous collision detection to resolve collisions between moving points and static lines, and collisions between moving/static points and moving lines. I already

  • Understanding LINQ to SQL (11) Performance

    - by Dixin
    [LINQ via C# series] LINQ to SQL has a lot of great features like strong typing query compilation deferred execution declarative paradigm etc., which are very productive. Of course, these cannot be free, and one price is the performance. O/R mapping overhead Because LINQ to SQL is based on O/R mapping, one obvious overhead is, data

  • Adding tolerance to a point in polygon test

    - by David Gouveia
    I've been using this method which was taken from Game Coding Complete to detect whether a point is inside of a polygon. It works in almost every case, but is failing on a few edge cases, and I can't figure out the reason. For example, given a polygon with vertices at (0,0) (0,100) and (100,100), the algorithm is returning: True for

  • How to offset particles from point of origin

    - by Sun
    Hi I'm having troubles off setting particles from a point of origin. I want my particles to spread out after a certain radius from a the point of origin. For example, this is what I have right now: All particles emitted from a point of origin. What I want is this: Particles are offset from the point of origin by some amount, i.e

  • Easy Profiling Point Insertion

    - by Geertjan
    One really excellent feature of NetBeans IDE is its Profiler. What's especially cool is that you can analyze code fragments, that is, you can right-click in a Java file and then choose Profiling | Insert Profiling Point. When you do that, you're able to analyze code fragments, i.e., from one statement to another statement, e.g., how

I know that there is a layer available from Microsoft called POS.NET, but I want to try and avoid using this. Any ideas or

  • Does Guest WiFi on an Access Point make any sense?

    - by uos??
    I have a Belkin WiFi Router which offers a feature of a secondary Guest Access WiFi network. Of course, the idea is that the Guest network doesn't have access to the computers/devices on the main network. I also have a Comcast-issues Cable Modem/Router device with mutliple wired ports, but no WiFi-capabilities. I

    I have a 2D rectangle with x, y position and it's height and width and a randomly positioned point nearby it. Is there a way to check if this point might collide with the rectangle if closer than a certain distance? like imagine an invisible radius outside of that point colliding with said rectangle. I have
