• Game Technologies: DirectX, XNA, XACT, etc. Perspective Shadow Mapping

  Hi all, I've read the Stamminger paper over and over again, but I still can't get my head around the concept. I've had no problems implementing simple shadow mapping (in fact the SDK example proved invaluable), but I'm at a loss as to how I'd implement perspective shadow mapping as described by stamminger to help correct some of the aliasing issues I'm getting. Can anyone describe the algorithm in plain english t.i.a Rob Meridy Thanks for the reply, I've come across that article before, and it does do a good job of explaining simple shadow mapping, but it only vaguely mentions the newer (c. 2002) technique of perspective shadow mapping. I understand and have implemented the technique of ge ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How much of a 3D engine will be included in the XNA Framework?

  In the DX samples there are the samples framework. Will that be built upon or will there be a separate 3D engine included or downloadable - What I am looking for is some kind of scene graph - Lighting and materials - Shader loader, constant setter etc. I am guessing since Torque are releasing their engine for this we will not see a full featured engine included but will there be an embryo that is more than the DX sample framework Regards Joachim With regards to the content pipeline, will it be possible to extend it to package (and possibly encrypt) content, and if so, to what degree; write a single class, or rewrite a dozen ...Show All

• Visual C++ Project corrupted?

  I'm having a tough time and I hope someone can help me out. I tried to add some DirectSound support to my project. All I did was declare the linker path in the project settings dialog, added a couple of lib files in the Additional Dependencies, and included a header file. My project wouldn't compile due to errors in Dsound.h (a microsoft DirectSound header file). When I commented out the Dsound.h include directive that I had added, all of a sudden I get linker errors referring to other parts of my project that had been working fine (!), for example "unresolved external syn=mbol" referenced in MyApp::InitInstance(), and a host of others. I've removed all the changes I made to my project settings but the linker errors remain. This ...Show All

• SQL Server Report Model Generating Out of Memory Error

  I am creating a report model of a large database with a few hundred tables, the idea being that the users can report on any part of the database and create perspectives for the areas they want users to have access to (In the past the users have moaned about report models in a CA product called Eureka as the models are too small, perspectives seemed a way of allowing one large model but limiting each perspective to a set of users ). Unfortunately presumably due to the size of the model visual studio is giving me an out of memory error when adding new tables. I have a two dual core xeons with 4Gig of ram and I'm running XP Pro 64bit with the developer edition of 2005 with service pack 1 and VS2005 is using around 1/2 a Gb. Is this a known i ...Show All

• Visual Studio 2008 (Pre-release) Is it possible to add Calendar and popup controls in ListView using WPF?

  Is it possible to add(or invoke on MouseClick event) the calendar controls and popup controls into the ListView cells in WPF Whenever the column(cell) is clicked, the calendar control should be shown and if we clicked in some other column(cell) it popup menu should be shown. Is it possible when using ListView with Gridview Also one more doubt is that, can we include the lines between the columns(as like grid lines shown in normal VS datagrids). As of now when i am using ListView with GridView, the values are displaying properly but the grid lines are not shown. I need these functionalities in my application. How can i achieve these functionalities I think you can do this using style. Else, you shoud redefine the temp ...Show All

• Software Development for Windows Vista Implement Custom Container Activity

  I would like to know if the following is possible (I am using the WF release canidate). I would like to create a custom activity that is a container activity (such as the built in while activity and sequence activity where you can drop other activities into the activity). The point of this activity is to allow the user, through me hosting the designer, to drop other of my custom activities into this container. The other thing I would like to do is restrict which of the custom activites they can put into the container (like how the handle external event activity requires that the first activity have certain characteristics). Can I do this If so, what is the best method of approaching this problem. Thanks. Amanda ...Show All

• SQL Server Validation issues

  Hi there, I have a package that runs fine in BIDS, however fails when run in a job with the following error: "The Validate method must succeed and indicate the result using an "out" parameter". The task it is failing on is a third party FTP task that uses expressions for the filesource and filedestination and username. I have set delay validation on for this task, yet it still seems that it is trying to validate it. Any suggestions Thanks.
