• Game Technologies: DirectX, XNA, XACT, etc. Terrain & Terrain-Physics (intersection, dynamic slicing)

  Hi, at the moment i am wondering how to deal correctly with a terrain in XNA. For now i just have a static terrain model loaded from file. So i have an object (a buggy for example) and want to get some physics on it, therefore i need to check for collision with the underlying terrain. The collision with the buggy could be done with a boundingbox, but the terrain needs to be checked per face (3 vertices triangle) i think. But i cant find a way to check this. I think iteration throught all faces of the terrain would take to long for all objects in the world. How do other developers solve this problem So if I do it this way i will always need to calculate every object in the world each frame, no mather if its visible or not, is this th ...Show All

• SQL Server How to enforce SQL Server 2005 to use Worktable?

  I have a problem in SQL Server 2005. In some cases SQL Server produces an execution plan of complex query (8 joins of views, some of views contains couple of joins) which does not contain a woktable creation in tempdb. As a result time of query execution increasion for about 5 seconds to about 4 minutes. All necessary indexes are created. It sims all data located in cache.

• Visual Studio 2008 (Pre-release) Introduction to WCF.

  Hello, I am new to this thread and WCF technology. I have read a little-bit about WCF, but have not yet understood clearly the technology. I have seen various MSDN resources etc, but find them talking too abstract rather than hitting the real point. I understand that this technology does have some advantages over existing .NET Distributed technologies, but I fail to visualize a scenario where WCF 'PROVES' itself over existing technologies. It would be a great help if you'll can help me in clearly understanding the technology and actually outlining the differences between .NET 1.1 or 2.0 based Distributed technologies and WCF. I would really appreciate if you can bring out exact scenarios and how they fare in both the cases. So, for e ...Show All

• Software Development for Windows Vista GraphEdit records fine, corresponding code does not

  I have got DirectShow running nicely for viewing a standard webcam video stream. The graph is registered so GraphEdit sees it-- here is a summary: capture filter(Logitech web cam) -> Smart Tee -> Capture branch-> MUX -> File writer -> Preview branch-> Video Renderer However, when I capture the stream and save it to an .avi file, the file is unreadable. The strange part is that if I use GraphEdit to remotely see the DirectShow graph and then run the graph via GraphEdit, then the .avi file is fine. The properties page of the good (GraphEdit written) file shows a framerate while the one run directly from code does not (all other parameters such as size, resolution, compression format (uncompress ...Show All

• Windows Forms Small accounting application Big headache (SAAB-H)

  Hello, This is part of a small database EntryForm. 9 TextBoxes: 1,2,3,Sum1 (all decimal(6,1), -- V1, V2, V3, EA, VTotal (all smallmoney) , --- EA (smallmoney). Three calculations: Sum1=1+2+3, V1=EA*1, Vtotal=V1+V2+V3. The order of the TextBoxes is 1-EA-Value1, 2-Value2, 3-Value3, Sum1-ValueTotal. The Sum1 and ValueTotal should be always updated regardless in which field the user choose to start entering data. The reason for the If, Else or If ElseIf statements is to always have some values in the TextBoxes. Note: All the TextBoxes.Text was stripped away to see better (1 is 1TextBox.Text, etc) Questions: How to initialize the Form without Fill (it always brings up the first record -eve ...Show All
