directx

问题 I have a computer with Windows 7. I have got 3D simulator installed. This simulator provides window. I want to place transparent window on top of simulator's window (with my extra drawing). Problem is that simulator's window switches to "full screen exclusive mode" on mouse click. That makes hardware work faster. But that hides the rest of windows (even topmost) including mine transparent window. Is the a way to disable full screen mode? 回答1: This is very interesting post (and it is related

问题 I'm using Direct3D 9 to draw lines. The vertices I am using now have the format D3DFVF_XYZ|D3DFVF_DIFFUSE and are stored in a vertex buffer. They are drawn with DrawPrimitive as D3DPT_LINELIST . How do I change the drawn color of a the whole drawn vertex buffer or even a specific vertex without locking the vertex buffer to modify it's content? This has to be done every frame. Is this possible with a vertex buffer? I would prefer a solution without a custom shader (using the default direct3d 9

问题 I'm attempting to draw a 100x100 grid in DirectX11 using C++, but the following issue happens: The image above shows a grid I am drawing in wireframe, using a rasterizer with its fillmode set to 'D3D11_FILL_WIREFRAME' and a 'D3D11_PRIMITIVE_TOPOLOGY_LINELIST' topology. The lines of the wireframe appear staggered rather than straight, with some parts of the wireframe missing. As I'm not sure what this issue is referred to as, I'm not entirely sure what I should be looking for and as such, any

问题 I have 0 experience with D3D. I am currently reading Frank Luna's book about D3D11 and trying to make examples working in C# using SharpDX though w/o effect framework. I stuck with texturing now. I don't understand how to load texture from file and how to send it to shader. Official wiki is dead. Or at least it doesn't load for me. I searched here but found only some way to do it with SharpDX.WIC which is with D2D so it looks a bit weird for me to use some D2D components in D3D app. 回答1: Look

问题 I can't seem to find a way to let myself read the data from my AMP array. What I want to be able to do, is take my buffer, copy it into a vector and then use the vector. I'm aware that I should set the CPU access flags, but I'm having trouble doing so. Firstly, this is how I'm trying to access the buffer. I'm putting this here first just in case I have done something how it shouldn't be done. Perhaps there is a function built in that I've missed that does this for me? std::vector<Pticle>

问题 I've been trying to send key presses to a DirectX application for a little while now, and keep striking out. I'm new to C#, so some of the more complicated functions go right over my head, but I've been trying to piece it together best I can. SendInput is one of those things that I just can't seem to grasp. I've tried using a few different SendInput wrappers to simplify things for me, including: http://inputsimulator.codeplex.com/ http://www.codeproject.com/Articles/117657/InputManager

问题 Does anyone know if it is possible to grab a frame/image from a video (.wmv) on position X using C# without installing DirectX and working on Windows 2008 (a webserver I would like to install as less as possible). Or even a simple solution with directx could be nice. Henk 回答1: What you'll actually need to look into is DirectShow, the general-purpose media (both audio and video) library for Windows. It used to be part of DirectX but several years ago it branched off and became part of the

问题 I just asked a question Spot the flaw c++ code earlier and realised that not having ValidateRect in my application at the message handler causes tremendous slow downs why is this?, how could this affect a directx application in such a manner? //----------------------------------------------------------------------------- // Name: MsgProc() // Desc: The window's message handler //----------------------------------------------------------------------------- LRESULT WINAPI MsgProc( HWND hWnd,

问题 Im trying to write up a 3DS Loader, which has an OpenGL rendering implementation for use in my generic rendering system. The problem here is I have vertices indexed to one array, and texture coordinates indexed to another. I dont want to generate a new set of indexes and original vertices by checking each vertexes combination of coordinates and texture coordinates, so how do I specify the two arrays in buffers in directx optimally? What I'd like is to have 3 vertex buffers, one for vertices,
