getting started with DirectX. I will simply use the State mode to tie all the examples together. Beginning Direct3D Game Programming After obtaining a lawyer's degree, the author became a game programmer. Although this book is positioned as an entry-level book, its content has unique merits. It uses the DXSDK Sample Framework instead of the currently accepted DXUT. There are two ways to compile, one is to rewrite it into DXUT. Second, find the old S

Its source code is as follows (in render \ direct3d \ SDL_render_d3d.c ). static int D3D_CreateTexture(SDL_Renderer * renderer, SDL_Texture * texture){ D3D_RenderData *renderdata = (D3D_RenderData *) renderer->driverdata; D3D_TextureData *data; D3DPOOL pool; DWORD usage; HRESULT result; data = (D3D_TextureData *) SDL_calloc(1, sizeof(*data)); if (!data) { return SD

restricted to the ddsurfacedesc2 field, but a standard ddsurfacedesc2 structure can and should be used. Use the magic DDS value and the header dwsize value to validate the file. Use the magic DDS value and the header dwsize value to verify the file. the pixel format of the image is given in the ddpfpixelformat field of the header, and can describe all the formats supported by direct3d. the pixel format of the image is supported by all

Master Program (The application host)To add our own program control layer, we will resume our own class based on the class provided by direct3d sample framewrok. The framework class cd3dapplication serves as our base class. We use it to initialize and enumerate video devices, create display modes, and process basic window messages. In this class, we will establish our own resource and device management class, control the execution of our programs and

The basic Lighting Model OpenGL and direct3d provide almost identical fixed-function lighting models. in our example, we will use a simplified version that we will refer to as the "Basic" model. the basic model, like the OpenGL and direct3d models, modifies and extends the classic phong model. in the basic model, an object's surface color is the sum of emissive, ambient, diffuse, and specular lighting contr

Recently, I changed the previous Code. Now the terrain is basically complete. The basic technology is geomipmap + block terrain, currently, the image is loaded with a height of 1024x1024. The frame rate is still good. There are more than 60 frames, and my video card is 9300gs. This is not a good video card. Today, I was planning to combine the previous atmospheric rendering. I didn't expect that the problem had never been solved. I was asked in a group that I was kicked out directly. Is it too m

(Laugh ). Direct3d is the core component of DirectX. It is responsible for drawing all the images (d3d for short). Because of the encapsulated relationship, it is very convenient to use. To use d3d, we need to do this: Create an idirect3d object. If you are a beginner, you can understand it as a class with no data members but only function members. The essence of idirect3d9 is a COM interface. Therefore, we can't see any internal details. We can on

(This article is written on: 21:50:03) [About d3dfvf_xyz and d3dfvf_xyzrhw] 1: If you use the vertex format d3dfvf_xyz, direct3d performs views, projections, world transformations, and Ray calculations before you can get the objects you have drawn in the window. The coordinate system is the left-hand Coordinate System in d3d. the X axis increments to the right, and the Y axis increments upwards. 2: If the vertex format d3dfvf_xyzrhw is used, it ind

advantage, of course, the disadvantage is that it is not possible to use a high depth resolution to represent near objects.　　From the perspective of hardware implementation, almost all hardware 3D acceleration CARDS support Z-buffer, while W-buffer does not support Z-buffer as widely. In addition, early direct3d versions do not seem to support w-buffer.　　Z-buffer and W-buffer ConversionAccording to the matrix transformation above, you can easily expo

A problem I encountered while developing my source filter's output pin is that inside fillbuffer method, the media type and size of the media sample is not exactly the same as the one I proposed in getmediatype method. the strange thing is my pin has successfully negotiated with downstream Renderer Filter (its actual type is video mixing Renderer-9 filter), and its input pin has agreed to use the m EDIA type my filter proposed. So why the actual media type being used changes? The answer lies

As the first program, Empytproject only demonstrates how to bind a callback function in a dxutstate structure. (I don't understand the meaning of the callback function here, where is the child window of the callback function bound, the control?) ）Use the DXUT framework to simplify API calls for Win32 and DirectX.Each callback function is described below, referring to the relevant introduction in DirectX11 , the situation of DirectX9 is similar 　　Device Management and initialization Dxut pr

The vertex data in the vertex cache represents the graphic to output to the screen.Four, flexible vertex format FVFIn D3D, vertices in a vertex cache actually contain a number of attributes, such as vertex coordinates, color, normal direction, texture coordinates, and so on. With the flexible vertex format, users can customize what information is included in the vertices, n
