Game Technologies: DirectX, XNA, XACT, etc. Terrain?
Anyone know a good way to make dynamic terrain and quickly at that I can read a black and white image file and read the grayscale and calculate a heightmap but it doesn't seem efficient to me or easily changable (if thats a word). :) Any help is always appreciated. Thanks! Yes, cutting your terrain up into tiles is a good start, I cut my heightmap up into chunks of 33x33 vertices, and I keep these tiles in a quadtree. I can then cull large portions of the terrain tiles based on the view frustum, but again this is just a size I have chosen you might want your tiles to be bigger than this. If you want the terrain chunks to load from disk (I think the term is terrain paging but not sure) as the use ...Show All
Visual Studio Team System Associating a test with a requirement
What a concept. Being able to tell what requirement a particular test validates. Wouldn't it be nice to tell what the test to requirement coverage ratio is Well, I'm going to try and hack my way through it. What I'll need to do is get the unique identifier information out of the test. How do I go about that I know I can get into the tests XML file and read out the properties but I haven't been able to locate an API to do it programatically yet. Can someone point me in the right direction This is where the uniqe id is in the tests file: - < id type =" Microsoft.VisualStudio.TestTools.Common.TestId " > < id type =" System.Guid " > 7521d7ef-4ac7-4bda-a5a2-67e521b1faae < ...Show All

Software Development for Windows Vista filter compilation under vista issue
Hi all, I am trying to compile a directshow in-trans filter using the VS2005 over vista. This filter was compiled fine under VS2005 over XP .

Visual Basic Text color
Hi, I have a little sub here to add a line of text to a richtextbox and set the color of the first line. It works fine for the first line, but for some reason after setting the color of the first line, it sets the rest of the text in the textbox to the color it used for the first line the previous time the sub was called (which obviously isn't what it should be). Here's the sub (oType is an enum but I don't think that'll be the problem) well that idea goes out the Window! :-) I'll see what else I can come up with ,reading the docs it should do it but think im missing something edit: the behaviour I have seen is that when you select the text and color it, then unselect the text and set the selectioncolor to something else, then on th ...Show All
Game Technologies: DirectX, XNA, XACT, etc. (Clip) Plane transform?
Hi all -- I'm porting a water shader to XNA, but first I need to get my clip planes right. I noticed we still need to unproject the plane from camera space to world space, but I cannot find a method that actually allows to transform a plane! Like the MDX Plane.Transform method used to do. I tried to transform 3 world points with the inverse of my world*view*proj matrix, and create a plane including these points, but no luck. There was a bug introduced into the Beta 2 Plane(Vector3,Vector3,Vector3) constructor. It doesn't correctly initialize the plane, so you'll need to calculate it yourself. Here's some code for how I do (you may need to change the order of the vertices for your own program): public static void CreatePlane(re ...Show All
Smart Device Development RFID Reader Project
Hello, I'm currently working on a project which involves a serial port RFID Reader. I have connected the Reader to COM2 of my PC and i'm trying to get the signals from the RFID Tags. I'm using Visual C# and SerialPort class. I'm doing this just to ensure that the code works and when i'm done with this i will modify the code for an iPAQ (the Reader works on COM7 on iPAQ). The problem is that i can't read or write to the port. I even tried to write something to the port using port.Writeline("string") and then read it with Readline() but it seems that nothing is written and nothing can be read. When i set the RtsEnable to TRUE the BytesToRead property changed from 0 to 9 no matter what i did and still i couldn't read ...Show All
Software Development for Windows Vista Acessing Functions in a Filter
Hi Guys I'm trying to get Informations out of a Filter I have programmed. In a Application I would like to get Information out of this Filter. I built the filtergraph manually and the Filter runs perfectly. But how can I acces Methods or Variables in the Filter My Idea was to give the Filter a function pointer and to set the function after instantiation. But this of course doesn't work since I cannot access the functionpointer via the IBaseFilter object.. I would be very thankfull for help kind regards ...Show All
Visual C# Code alignment lost

Software Development for Windows Vista Problem with maximized MDI child window
I have a straightforward MDI application with four MDI child windows. The MDI client window fills the entire client area of the application's top-level window. Everything works correctly on Vista except in this one circumstance: If the application's top-level window is maximized *and* one of the child windows is maximized, the child window does not fill the width of the MDI client window (and hence of the screen). There is a strip (perhaps 10 or 20 pixels wide) down the right-hand side where the previous contents of the MDI client area can be seen - it is not repainted. If the top-level window is not maximized all is well: the maximized child window extends to the right-hand edge. If the top-level window is mazimized but the client w ...Show All
