What is shader A Shader (shader) is a program that operates on a 3D object and is executed by the GPU. Shader is not a unified standard, and the shader of different graphics interfaces are not the same. OpenGL's coloring language is GLSL, Nvidia has developed CG, while Microsoft's Direct3D uses the Advanced Shader language (HLSL). Unity's shader is a code-generation framework that embeds the traditional graphical interface's shader (written by CG/HLS

Lost DeviceOne Microsoft? Direct3d? It can be in an operational or lost state. The operation status is the normal status of the device. The device runs as expected and present all rendering results. When an event occurs, if the full-screen application loses the keyboard input focus, the device changes to the lost State, resulting in rendering failure. The loss state shows the silent failure of all rendering operations, which means that even if the ren

We recommend two books on d3d and 3D graphics mathematics. Recently, I was asked about d3d and 3D related mathematics books in Chinese. We recommend the two. I will not write book reviews. But these two books are really good. If you buy it, you will not suffer losses. Introduction to Direct 3D game programming (version 2)D3d recommends this one.

dynamic texture or a private FOURCCDriver format. To access texture resources that cannot be specified, you must use the following function: IDirect3DDevice9: UpdateSurface IDirect3DDevice9: UpdateTexture IDirect3DDevice9: GetFrontBufferData IDirect3DDevice9: GetRenderTargetData For most applications, using D3DPOOL_MANAGED is a better choice. Some textures created in pixel format unique to driver cannot be identified by Direct3D runtime, and can also

DirectX SDK documentation. Microsoft DirectX 9.0 SDK Update (summer 2003) Or Microsoft DirectX SDK (April 2006. Microsoft DirectX SDK (CMDL 2006) is in the directory J: \ Program Files \ Microsoft DirectX SDK (CMDL 2006) \ documentation \ directx9. This document is only a reference for getting started with DirectX and used to query DX APIs. The dx sdk is updated in just a few months and is very fast. Therefore, you can pay attention to Microsoft's DirectX site on Monday. Http://www.microsoft.co

information in system memory in our application. however, when we feed the GPU the vertex buffer containing our vertices, we are just feeding it a chunk of memory. the GPU must also know about the vertex layout in order to extract correct attributes out from the buffer. to accomplish this requires the use of input layout. In direct3d 10, an input layout is a direct3d object that describes the structure of

If a friend is looking at some of these blog, then congratulations, you will see the history of the most rotten blog about DirectX, haha, there is no understanding of the time to communicate AH. There are too many things to tell about DirectX, like the textbooks I mentioned in my last blog, which are the Bible of the game world, and suggest that you look at the entry level. So I'm going to explain it in a note-taking. initializing DirectX The initialization of DirectX is divided into four ste

Here I want to continue writing something related to the Mesh. After all, we may need to have many other requirements for it. In practical use of 3D games, low polygon models are generally used. In this way, we can have a better speed to run the game. In fact, DX provides us with such a function that allows us to control the complexity of the read Mesh.Public void WeldVertices (Microsoft.

Chapter 6 mesh objects 1. What is mesh?We have already touched on the mesh class. Here we will introduce in detail that the mesh can be used to store any type of graphic data, but it is mainly used to encapsulate complicated models. The mesh class also has some ways to improve the rendering object performance. Mesh can be used to read 3D model files from external files, such as Maya files, so that models can be completed in 3D Max or Maya Software and then read into the program. Mesh objects als

the horizon body should be discarded during further processing. The operation process of discarding such data is called cropping. A 2D area in the projection window, where 3D ry in the horizon is mapped to the area by projection, a 2D representation of the 3D scene is created.It is important that the minimum values of the rectangular projection window coordinates in the X and Y directions are min (-1,-1) and max)Direct3d defines the projection plane

3D primitives In direct3d, polygon is composed of triangles. Because the three vertices of a triangle are always in common, rendering of non-common images is inefficient. Therefore, various ry in direct3d are made up of triangle elements.Rasterization rules (raster Rules) Triangle Rasterization rules: direct3d uses top-left filling to fill the ry. the center poin

Using a simple rendering technique Translation: ClaymanSo far, our rendering efficiency has been low. Each time the scene is rendered, a new vertex list is assigned, and everything is stored in the system memory. Modern graphics cards are integrated with enough video memory to hold vertex data in memory for a significant new boost: data stored in the system's memory and copied to the video card when each frame is rendered, resulting in a huge loss. This allocation can help us improve performanc
