• Randy R Jackson Some questions about Vista & Direct3D 10

  Hello! Greetings from Ukraine! I am still programming under WinXP and DX9. But I'm going to port my code into Vista platform and cannot find some information I am interested in. According to numerous articles and documentations porting is to be painful:) So, I have some questions listed below: 1. When will (approximately) the nVidia or ATI accelerators support Shader Model 4 2. How shall I use SIMD advantages on the C ...Show All

• Jack2005 Lighting large meshes

  [Ignore the fact that I work at MSFT and my sig says "VS Platform Team". I'm posting this as a user, not an expert ] I'm using the December SDK and writing a C# application that uses Managed Direct3d. In one view I have a mesh, some ambient light and a directional light. I'm not using specular lighting (RenderState.SpecularEnable = false) and I'm using Gouraud shading (RenderState.ShadeMode = ShadeMode.Gouraud) If I rende ...Show All

• prigun Linker errors

  In our game engine the audio and the scripting system are plugins so I have created an XACT audio plugin for our engine. The problem is that some parts of the scripting system plugin includes xact.h because it needs access to some of the xact structures, but this causes linker errors for the scripting system because xact.h contains a macro that uses CoCreateInstance. Would it be possible to have #ifdef NOMACROS around the macros so they ca ...Show All

• Page123 Creating a new texture fails with "first chance exception"

  I have an application in which I create a texture to later write directly into. It works fine on my development machine, but on the target machine it fails with A first chance exception of type "microsoft.directx.diretct3d.invalidcallexception" occured. The code looks like this texture = new Texture (renderer.Device, 720, 576, 0, Usage .None, Format .A8R8G8B8, Pool .Managed); The pixelformat is the same as the device. ...Show All

• jack7701 Targeting older machines

  Hi there. I guess part of this is more of an opinion question. I want to target older machines that may not have up-to-date graphics cards. Right now I am using a game engine that gives the developer the option of using DX8, DX9, or its own software driver. To compile the engine, I naturally need the DirectX SDK. Problem being that the latest realeases don't have DX8 support. So the question becomes: Is DX9 a 'safe' way to go f ...Show All

• uclimng Does DirectX have the OpenGL equivalent of Display lists?

  As the subjects asks, is there an equivalent  feature in DirectX Basically I want to just render about 200 spheres most of which will be the exact same copy of each other. Drawing each sphere independently of each each other gave quite poor performance in OpenGL until I used Display lists which enabled me to save a fixed set of drawing commands and just call the display list instead of redrawing the sphere each time. ...Show All

• sprague295 DirectSound under VS2005 - null reference using buffer notifications

  Hi, I'm very new to DirectX. Using VS2005 and the December 2005 SDK I have created a very simple winforms app that plays a WAV file. This works fine. I then tried to add buffer notifications specifically so I could detect when playback stops. Immediately though I hit a stumbling block, when I instantiate a new Notify instance I get a null reference exception. The buffer parameter is most definitely not null. This is a cut down version o ...Show All

• kalyanic Matching view to world - help!

  1. I have a number of meshes placed in world space. 2. Each mesh is being rendered using three vectors: scale, rotation and position. 3. I am calculating the world matrix with SCALE_VECTOR * ROTATION_VECTOR * POSITION_VECTOR . 4. One of these meshes represents the camera. So, when rendering this mesh I also set the view matrix. 5. The view matrix is calculated using LOOKATLH using the POSITION_VECTOR as the eye and POSITION_VECT ...Show All

• AZ17 Fundamental Graphics.

  Hello. I'm aware this question likely comes up frequently, but I don't want the answer "Use DirectX". - That's not really what I'm looking for. A friend of mine learned C++ using Borland's ancient Turbo C++ compiler - and it, of course, had a ton of specialised functions, like a gotoxy(x,y) for co-ordinate placement in the console window for text output, and things along those lines. However, he learned graphics the hard way. ...Show All

• Eric Y. Adaptive, temporal Anti-aliasing

  Hello, how do I enable ADAPTIVE or TEMPORAL anti-aliasing modes in the Direct3d API I dont think you do - the various AA modes seem to suffer hugely from various PR and marketting spin when it comes to naming. It might be possible to request a particular combination that the driver can interpret as being one of the special modes, but what (if any) such combination is going to be IHV-specific. The Direct3D ...Show All

• JennaG Centre view on a rendered object

  Basically, i have a little app going on where the app renders a direct3d surface, and the user can click on various items that are being rendered so they can centre the view on that item. Now, the problem i'm having is that i can't make the view centre on one of the objects by using a mouseclick. I can get the mouseclicks coordinates relative to the 3d window. i.e. i can say they were at coordinates 100,200 i.e. 100 to the right and 20 ...Show All

• WendyHod Are there any drawbacks to this?

  Hi again! I had this freaky idea earlier today where I decided to render my entire GUI to a texture and render this texture to the screen. This way, I don't have to go through my entire GUI rendering process every frame, which seems to double my framerate in GUI intensive situations. I only update this texture when when the GUI needs updating. I can't shake off this dodgy feeling that this can't be a good way to do things though. Is there ...Show All
