Finally, I have finished talking about the basic concept of space ry in the first three articles. Now I can say something practical. For a long time, I have always hoped to record some of my 3D knowledge in the most easy-to-understand language as a

As mentioned in the previous chapter, in a fixed pipeline, the first step is to perform coordinate transformation on the elements. The so-called primitive is a pile of vertices that constitute a specific geometric shape, which is called an element.

texture map. The third texture map represents the Environment Illumination ing of the surrounding mirror reflection or diffuse reflection. The concave-convex texture of direct3d is used to indicate the height difference between adjacent pixels on the object surface, each of its texture elements is composed of DU indicating horizontal adjacent pixel height difference, DV indicating vertical adjacent pixel height difference, and l indicating the bright

Significant improvements in D3D 11 to D3D 12The programming model of Direct3D 12 is very different from Direct3D 11. In Direct3D 12, applications and hardware are much closer, which has never been before. This makes d3d12 faster and more efficient than ever before. But the cost of speed and efficiency increases is that more tasks need to be done in the applicatio

Direct3d uses a texture coordinate system, which consists of a horizontal U axis and a vertical v axis. The elements in the texture are determined by the U and V coordinates. It is called Texel . Note that the V axis is down. In direct3d, you can set eight textures (which are, correctly, eight-layer textures), which can be combined to create images with more details. This is also called multi-texture.T

, not only is the desktop of Vista and 7 itself a 3D application, but because Vista and 7 can better play the role of graphics acceleration hardware. From Windows Vista to Windows 7, the operating system and GPU are becoming closer and closer together. Although people often hear that the major update of Windows 7 is a DirectX 11.0 API, DirectX is also very important for the graphic architecture of Windows systems, but this is not all. A graphic architecture includes how to use GPU to accelerate

(Windows 95 and Windows NT ). Because GDI was developed for computers with low computing power a long time ago, it does not have features such as anti-aliasing, and most APIs do not support alpha channels. During Windows 95, DirectX released the first version. DirectDraw is one of the earliest components. It was originally intended that, when hardware acceleration was enabled, developers could bypass wing's permission to directly access the hardware. Such a protocol stack can be in the same s

Today is the first time I open my website here. I will first explain that writing this document is not a tutorial. I am not an expert either. I just want to have a deeper understanding of direct3d, at the same time, if you see these things unfortunately, I hope it will be helpful to you. At the same time, I solemnly declare that this post will not be reprinted. I am not an expert and it is inevitable to make mistakes. However, if someone else is misl

ObjectiveRecently studied the technology of AV playback under the Windows platform. In the Windows platform video playback technology mainly has the following three kinds: Gdi,direct3d and OpenGL; audio playback technology is mainly DirectSound. These technologies are relatively low-level technologies, so they are more complex to use. I also learned in the process of the lack of a relatively simple and intuitive sample program, so I intend to do some

acceleration hardware. From Windows Vista to Windows7, the operating system is increasingly integrated with the GPU. While it is often possible to hear Windows7 's big update on a DirectX 11.0 API, DirectX is also important for the graphics architecture of Windows systems, but that's not all. A graphics architecture includes how to use the GPU to speed up a wide variety of graphics applications (2D, 3D, print, etc.), display to the final display device, and include device detection and control

Coordinate system and basic elements (1) Direct3d Basic Elements Primitives is a basic graphic representation defined in direct3d. It is a set of vertices that constitute a single object. The simplest element is a set of multiple vertices in a three-dimensional coordinate system. It is called a point list ). A polygon is a polygon. A polygon is a closed graph composed of at least three edges. The simplest p

Tutorial 1 in the official help document translated by myself, I felt very happy last night. If a newbie finds it hard to start, let's take a look at my article. The following are the VC settings. (My SDK version is old. It is 9.0april2006) Step 1 create a Windows windowThe first thing a Windows program does is to generate a program window when it is running and display it to the user. To achieve this, the createdevice example starts running in its winmain function. The following code demonstra

DirectX is a game API on Windows. A few years ago, game developers struggled with hardware incompatibility, making it difficult for everyone to play the same game. Later, Microsoft launched DirectX. It provides a single and clean API for game developers to achieve compatibility with different types of hardware. Due to the release of DirectX, the number of games on the Windows platform has increased significantly. This chapter contains the following content: Understand what DirectX is Why is D

member of our class is defined as a virtual function. Note that the current member function is not a system attribute. Tip: I deleted the access functions. I didn't use the access functions in cparticle. Ambassador I decided to use them here. We often use the client code cparticleemitter. It may very rare that when the client changes, it will directly change the attributes. Most of the time, only the contact class will be cparticleemitter. However, the client will be exposed to cparticleemitter

This article records the OpenGL Video Playback Technology. OpenGL is a technology at the same level as direct3d. Compared with direct3d, OpenGL has the cross-platform advantage. Although in the gaming field, DirectX's influence has gradually surpassed OpenGL and is adopted by most PC game developers, in the field of professional and high-end graphics, OpenGL is still the main character that cannot be replac
