Normal maps are used for realtime 3D rendering (mostly in games) to improve the visual quality, but compressing them makes the 3D content look ugly, this tool helps to fix that problem.
This brief article describes how to use managed Direct3D to render texture bitmaps with alpha channels and transparency key colours onto vertices in C# with the aid of a MatrixStack.

There's isn't a best one. Which one is right for you depends on what you want to do.If you want to make games on a mobile platform, you'll probably want to do it in the languages best suited for the platform (Java/C++ for Android, Objective C for iOS, and C# (I think) for Windows Phones,...
GPUToaster is correct, this has been discussed @ the Creators Club[^]..X formats are not designed for "editing" type procedures, if you want to do this you will need to be working in DirectX, or OpenGl, NOT XNA. Xna is designed for displaying, not making.

Hi,Nowadays technologies are so developed that they free developers from having to cover much of the 'technical' aspects of their job and let them concentrate on the core issues they have. One of such helpers is the core concept of object-oriented languages, and C++ too, which of course is -...
DirectX is the way alternative to GDI, a faster one. Moreover, even though GDI and DirectX can be used together, they poorly live together. To see it, it's enough to put some GDI object on top of, say DirectX-based video and see what happens. For resolving such clashes, a layout manager exists,...
Descriptors and descriptor heaps are key components of a new resource binding paradigm introduced in Direct3D12. This article describes an efficient system for managing descriptor heaps.

No, there is no general solution to this via DirectX.The reason for this is that the Window you're trying to capture may have no existance in DirectX at all. If it belongs to an application that doesn't use DirectX then from the DirectX point of view there is nothing special about that area...

AFAIK the vertex buffer cannot be read back. If you are trying to modify the UV sets then try duplicating Buffers. Because you will not get any performance difference.Try using search engines. :)
Use XNA, this has all the stuff that you need without going into the 3d portion of the API..and in the long run if you want to do things like sparkles, music, explosions.. or whatever else to augment your game you would have easy access to that stuff through XNA.GDI, and it pains me to...
The answer is simple: you can't.At least not the easy way. The Viewport3D control makes it possible to display 3D content in simple way, but there are many restrictions. For example it's not possible to draw lines (thus it's not possible to render a wireframe object, although there are...
Nothing against XNA, but WPF would be better for this. A card game may need not much of a GUI, but some may be needed and that would be a pain, especially for somebody who just got started.With WPF you get the user interface and also the cards (including transformations) with far less overhead.

Hey i m using this project DLL Source For Buffer-based MP3 Decoding[^]to decode a mp3 in a livestream and so i want to play it. but how can i write the output to a stream in directsound. Please help i cant find anything... have been using google 4 four days now
I suggest you use pure WPF 3D capabilities instead.It is not clear why using interoperability (System.Windows.Interop.D3DImage). However, if your still need it (legacy or other reasons), you need to show your code.—SA
HiI'm beginner in game programming and I need some good resources to start(some books or video tutorials and examples). I need the fastest way to learn it(XNA and DirectX games or even something else). So if you can give me something to start with fast I'll be grateful. Yeah and I would like...
I need a function that return if a certain point is inside a directx 3d model(.x)...I have tried but i can´t get it to work so i need some help.Something like this:public bool IsInsideModel(Vector3 point, Model model){ //This would of course be nice but i don't think such...
The good news: it can be done. The bad news: A precise test is computationally expensive and therefore probably too slow to be of any use in real time rendering.First off, it works only on convex objects. Concave objects would have to be broken down into two or more convex objects and then...
Hello all,I have search everywhere. I am trying to create a joystick event similar to a mouse click etc but all I can find is joystick polling (using a timer to check the state of the joystick.)I am using vb.net and DirectX input. Is it possible to create a class that can create a...
DirectX input for joystick work is a different way. You can create an Event (EventWaitHandle for .NET API) object which is set by the joystick driver interrupt on every input event. You can write code which fires events.Here is how: Create the input event object. Create a thread; in this...
Its a long time ago at DX7. At this time we have to gain a new back- and frontbuffer if the viewport size has changed. But thats no problem: the meshes and textures still exist anyway.But dont ask me for code, im afraid that i couldnt find it.Regards.
private void openMJEPGFileItem_Click( object sender, System.EventArgs e ) { URLForm form = new URLForm( ); form.Description = "Enter URL of an MJPEG video stream:"; form.URLs = new...
The only feesible solution I was able to find was to combine the two classes. If anyone else finds a better way PLEASE let me know I like to keep my code compartmentalized(or however you spell it).Thanks again for taking a look at my situation and thank you Richard for your help.--Steve
I should only add to the post of krmed that this linking libraries are called: - static link library - MSDN: When an application uses a function from a static-link library, the linker copies the code for that function into the application's executable file, and - dynamic link library (DLL) -...
yes, but with a different approach. A pixel shader from what I have read takes 1 pixel in and provides either none or some pixels out, whereas your function modifies a whole surface at once. The actual pixel shader function would effectively do one iteration of the outer loop; and global...
Hi, I wanted to find a way to capture DVD/CD playing video data before actually it gets displayed. I have read some where that using direct-x we can achieve this but not sure. Please let me know if it is possible.Any pointer or hint will be highly appreciable.
How can Direct2D and Direct3D can be alternative to each other? (Yes, I would recommend usign Direct2D and/or Direct3D.) It depends on character of graphics you want to create. Of course you can always model 3D objects and render them as 2D projections; depending on the problem, it may or may...
Hello,We had an application that used DirectDraw for drawing many pixels directly to the video memory at a high rate.As there is no more MS support for DirectDraw, we want to refresh this code.Does anyone any suggestion what is the best replacement? Direct2D? Dierct3D? DIB?We are in...
A friend of mine found the problem. The bytes in the stereo signature were in reversed order. Here is the correct order: byte[] data = new byte[] {0x4e, 0x56, 0x33, 0x44, //NVSTEREO_IMAGE_SIGNATURE = 0x4433564e; 0x00, 0x0F, 0x00, 0x00, //Screen width * 2 = 1920*2 = 3840 =...
I need to load a mesh(.x) file in vc++windows forms and display in the form window. Can any one guide me how to load and display (.X) files in vc++ windows formsThanks,Venky
Hi all,I am using directx to plot graph in WPF. Here D3dIMAGE i am using to render directx interface. My plotted graph is correctly visible in normal CRT monitor but same is not visible properly in Touchscreen monitor. Here vedio driver is same and board is same and only monitor is giving...
Do you use raw DirectX in WPF? Why? WPF itself provides you with everything to do plotting; its implementation is already based on DirectX. Just use WPF imaging capabilities and stay out of trouble.Plotting is a routine type of problems for WPF; WPF is perfectly equipped to solve...
Hi All.all of a sudden IDirect3D9::CheckDeviceType fails no matter what fomrat i give to it, even D3DFMT_UNKOWN.even if it says not supported, i set it to the format i gave to it aand it works.anybody know how to fix this?Many Thanks in Advance---edit---i tried using a slightly...
Hi allI was wondering and I know it is stupid but is there a way to make DirectX (directinput) not to see my mouse and/or keyboard, and I do not mean code wise like to code an app that doesn't use Directinput. I mean OS wise, to sabotage my PC so that any app using directinput can't see the...
I am trying to add a tiled texture to the floor. The texture does not show up, instead all the vertices are showing, and the ball now has a floor that follows it's bounce. Any help would be appreciated.//within winmain pGrid->CreateDirectXMesh(pd3dDevice); ...
I can't see what's happening inside of DrawDirectXMesh but If you can only see the vertex points instead of the actual faces that I can only assume it's rendering with D3DPT_POINTLIST instead of D3DPT_TRIANGLELIST. It might be easier to set up the vertices for the floor yourself and then render...
I set private Video MyVideo=null; .......(Omit some of the irrelevant) MyVideo.Owner = panel1; I want to play full screen by double-clicking to play goal, so with panel1_MouseDoubleClick () function to achieve, but in a real play, panel1 double-click event has been impossible, it...
I set the video's owener to a panel control.When I change the size of the control panel when I want the video aspect ratio remains the same.For example, the original ratio of 4:3 video to video, then I resize the control after the video playback screen size is still 4:3.Not filled part of the...
Hi there,I've just started using directx for my windows mobile application and i ran into a little problem that i could not solve so far.I'm trying to draw a polygon with complex coloring (like linear gradient) and i thought that if i create a rectangle 'behind' the polygon with the wanted...
C # video player by using directx, set its owener to a form panel control.I want to use the mouse hook to capture mouse double click event, but I do not know how to restrict in the playback screen when I double-click for the appropriate action.No matter where I am now double-click will perform...
OK i got a viewport3d and i have slimDX sdk, i searched through the code to know how to render the viewport3d using slimDX, and found nothing, basically i'm trying to hardware render a viewport3d which has some 3d object, to an image to save.or if anyone got a better solution than slimDX,...
I use C# and directx to develop a video player, I want to achieve the rotation, such as 90 degrees, 180 degrees so that how to achieve it? Thank you. I put the video owener set inside a panel control.
Hello everyoneHow do i access the TRANSFORMED pixel data for a texture, after it has been transformed by D3DXMatrixTransformation2D() and texture->SetTransform()?I'm trying to do 2D pixel perfect collision detection and it's impossible if you can only access the untransformed pixel data...
Let's put it this way: is it even possible to D3DXSPRITE->Draw to an off-screen surface? or just to the backbuffer?if somebody can link a tut or post complete code that'd rule
The Article is:DirectX.Capture Class Library[^]I could't find the DirectX.Capture.dll and DShowNET.dll dlls.Where can I fid it ?Thanks for your answers in advance..
You should post your question at the bottom of the article in question. It is good that you have linked to it, but the author will not see your question here unless they just happen across it.You may or may not get a response from him though, as the last time Brian left a message was back in...
