grid size, align the center of the grid with the center of the world coordinates. When we have a plane mesh, we will change the Y coordinate of the vertices in the mesh based on the data in the height graph, so that we can create a high and low terrain mesh. The following is my model: The following figure shows how to use the Phong color model to illuminate the point light source: Multi-texturing In texture ing technology, multi-texturing is used to combine different textures to form a textur

structure is consistent. Make sure that your stored code stores information in the order you want to load. 4.3. resource editorTo make your GUI shine, you must have a resource editor. Of course, you don't need to be as gorgeous and powerful as the resource editor provided by the development environment, but you have to have at least a basic program to complete addition, editing, deletion, and arrangement, this frees you from the trouble of calculating virtual coordinates for each control in th

I translated this book a long time ago, and now the source code CD is not around. Now, the source code owner can download the code in zbuffer. Most of the resource files except for Chapter 6 can be found in DirectX SDK. In addition, you can go to gameres to search for my original post titled "in-depth management directx9". Each chapter is followed by complete code and resources. In fact, I personally think that since xNa has been released, there is n

The Code logic of C # + DirectX audiovideoplayback circulating on the network for video players is basically: // Source code of csdn yalan old project After testing, it is found that although two video and audio instances are initialized for the code modification, there is a black screen interval between the player list (my project uses a generic list After analysis, there are two reasons for the interval of changing the black screen: 1.

　　Reason Analysis: This is not the case because the video card driver version is too old, but the graphics driver "too new." As Microsoft has stopped maintaining its XP system, Nvidia officials are no longer WHQL to sign up for the graphics drivers under the XP system. Therefore, when the XP system is installed with a too new video card driver, the DirectX feature will not work properly because the files in the graphics driver are not digitally signe

Delphi and DirectX Delphix (6): Allow Tdximagelist to interact with regular VCL This example tests two questions: 1, other VCL loaded pictures can be used for tdximagelist; 2, tdximagelist in the picture can give other VCL use. In the example, first load the picture with Tpicture, then give the tdximagelist; The picture is then drawn on the form, not in the Tdxdraw. Continue to understand point tdximagelist: The Tdximagelist control has only tw

experts say the DirectX rendering pipeline is divided into the following steps local coordinate system-> world coordinate system-> observation coordinate system-> projection-> viewport transform-> raster. For me, it's a couple of functions. transformation of a local coordinate system to a world coordinate system 1.

Reprint: http://www.cnblogs.com/graphics/archive/2009/10/13/1582773.html Viewport transformation after the projection transformation, the role of the viewport transformation is to convert the point on the projection plane to a point on the screen, which is a scaling process. The function of the projection transform is to project the scene in the viewing frustum (visual body) to a plane, which is the projection plane, in DirectX, using the near clippi

In a nutshell, The matrix in DirectX is used in 3 steps: 1. Define the world transformation matrix. 2. Define the viewport transformation evidence. 3. Define the projection transformation matrix. One of the first steps: D3dxmatrix Matworld;D3dxmatrixrotationy (matworld, timeGetTime ()/150.0f);//The information of the transformation matrix exists in Matworld, and there is no actual changeG_pd3ddevice->settransform (D3dts_world, matworld);//Set the

Seven or two-D display Most two-dimensional display in DirectX is done by Sprite, such as animation, bulletin board, two-dimensional text, and so on. There are special sprite classes in DirectX for simplifying sprite drawing and processing, and here's a look at some of the methods of the Sprite class: Method Defined Description Begin Public void Begin( spriteflags flags);

Recently in the map editor, want to take the BMP resources to do the mouse cursor, check the half-day data have not found ~ ~ And then you go to DirectX. DirectX is very good and powerful, with a few simple commands you can set the mouse cursor ~ 1 Create surface, where surface formatting must be A8R8G8B8 format, no matter how large the original image, will be converted to the size of 32*32 pixels. 2 Ca

The following code is the clock that the component implementation of the DirectX called. It has three pointers that will change in real time with the changes in the system. But I did not do the scale, because I think the program to draw the scale is not beautiful, using Photoshop to draw a bell as the background is much more beautiful.
