• R. Santana Shadow maps

  Hi I'm looking for some information about texture shadow maps. I've looked in goole for a sample, but i can't find one. The ones I found, or are incomplete or too complex (because they involved other more complex concepts, like soft shadows). The sample about Shadow Maps in the DX SDK run soooooooo slowly that it is very hard to properly study it (I think that's because it is meant for DX 10). What I'm realy looking, is a sample code as simple a ...Show All

  Hi, I'm new to vertex buffers and have been having some frustration with what I think is a beginner problem.

• Tim F Good source (s) to learn Direct X (c++)

  Hi, I have begun programming with DirectX and C++ for a while now (not a very long while =)) I've read the 6 tutorials that comes with the SDK and understand them quite well, but where do I go from here Most interesting info I find about DirectX programming for newbies is in managed, but, since I already can programme nicely with C++ (console and windows) I think that would be some kind of a step back, dunno why really... but is there any ...Show All

• kingdeadbo DrawImage(img, pts)

  Sorry if this is the wrong place for this question but it it related to 3D games programming... I have noticed that Graphics.DrawImage(img, pts) accepts an array of 3 Point objects in the second argument.  In the spirit of adventure I passed in an array of 4 to see what would happen (I was hoping it would render an image inside an uneven quad).  It did not work but it did throw an exception indicating tht this functionality had not ye ...Show All

• jimoctezuma Terrain Rendering

  I have a quick question... What are some of the best/simplest ways to render large terrains for games such as a MMO or a FPS like Far Cry I have skimmed over some LOD stuff using quadtrees and this seems to be ok but I was thinking of using an LOD technique that changes with distance from camera. I am not sure what this is called. But i was wondering if this would be a good way to go about it. Thanks in advance. One thing you may wish to ...Show All

  Is there a way to use DirectX to write to a monitor on a second display adapter when the monitor is detached from the Windows (XP Pro) desktop The MSDN library contains a topic "Using Multiple Monitors as Independent Displays" which suggests that one can use the GDI function CreateCD or the DirectX function DirectDrawCreate (now a deprecated function). What currently supported DX9 function will let me open the device and use it for ...Show All

• jimvrana Why so many big structures in managed directx?

  I was told to ask this question here to get an answer: struct Caps 304 bytes struct Material 68 bytes ... These big structures are used as properties and passed here and there. Isn't this a big performance penalty I checked the generated asm code, and it seems these's no optimization to remove the overhead. So anyone knows why Well, I admit they do not executes every frame so their drawback can be ignore ...Show All

• richdenis Corrupted texture on Radeon

  I'm using C# and managed DirectX to display a mesh with two texture stages. It draws fine on a GeForce, but looks corrupted on a Radeon X300 and also a ATI Radeon 9600 Pro. I think it started when I added a second texture stage to modify the texture color before rendering. You can see the results on both cards here: http://gosub.com/DirectXTextureError.htm Here's how I setup the render states: dx.RenderState.Lighting = true; dx.RenderSt ...Show All

• St1ck I have some artifacts with fog

  When I use Exp or Exp2 fog in vertex mode I have a strange effect with big triangles when I rotate the camera. I concluded that the fog calculations are wrong. When I use Linear fog all is ok. Small triangles also looks as they must. Do you have some ideas what is the problem Do you have range fog enabled It sounds like when you're using linear fog you're getting range fog, but when you using exponential fog you're not. Without range ...Show All

• jccondor Creating a very simple GUI

  I am trying to integrate a very simple GUI into the project I am working on. All I need is 3 edit boxes to accept values and a button to execute a command. That's it. I have looked at the tutorials included with DirectX, and the GUI example is simply too complicated...I don't want to include a bunch of files I probably won't even need. What's the easiest way to implement a GUI like the one I am describing (By the way , I am writing this in C++. ...Show All
