Coordinates can only be from-1 to 1, and can only be the right X axis, Y axis up, Z axis vertical screen. These limitations cause a lot of inconvenience to our drawing. We live in a 3D world-if we want to observe an o

Preface With the development of computer multimedia, visualization, and graphics technologies, we can use computers to precisely reproduce the colorful 3D objects in the real world and give full play to our creative thinking, it is the most fashionable VR technology to simulate and transform the real world through human-computer interaction. With this technology, construction engineers can directly design beautiful building models. Military commanders can simulate the battlefield for military d

list has been created. Glendlist (); // done building the top display list} The texture map code is the same as the code in the previous tutorial. We need a texture that can be attached to the cube. I decided to use mipmapping to smooth the texture, because I hate to see pixels. The texture file name is cube.bmp, which is stored in the data directory. If (textureimage [0] = loadbmp ("Data/cube.bmp") // load the bitmap The code for changing the window

OpenGL is a standard graphics library specialized in graphics processing, scientific computing, and other high-end application fields. Its main competitor is Microsoft's direct3d. OpenGL has long been a technology leader, but direct3d has also caught up in recent years. Currently, the two graphic APIs are similar in performance. However, OpenGL supports many oper

is useful to us. The width and height of the image are both a 32-bit integer. The addresses in the file are 0x0012 and 0x0016 respectively. Therefore, we can use the following code to read the image size information: Glint width, height; // use the glint type of OpenGL, Which is 32-bit.// The Int value of C language is not necessarily 32 bits.File * pfile;// Open a file hereFseek (pfile, 0x0012, seek_set); // move to the 0x0012 positionFread ( width,

Artists, which is available online.What is the difference between OpenGL 21 and Shader Moder 41? Is it true that all graphics cards support both of these technologies? The shader model 4.1 refers to the 4.1 version of the shadow. Only the graphics card that supports Microsoft's graphic interfac

for different types of rendering. The is gl_modulate, which modulates of the current lighting and color information with the texture image. Gl_decal is the second mode which only uses the texture image. Color and lighting information would not affect the texture ' s appearance. The last mode was Gl_blend, in which the texture image is blended with the current texture color and the current lighting a nd color information. Texture Filters OpenGL uses

Qt + OpenGL game development materials Beginning in December 29, 2012, I finally ushered in the last winter vacation of the University. This winter vacation is really long. There are nearly four months in total. During this period, the school asked us to create a graduation project and write a preliminary paper. Graduation Design is still good, because I have done a good job in the preliminary research. The rest of the time can be used to learn how to

Lighting and keyboard control: In this lesson, we will add lighting and keyboard control to make the program look more beautiful. This lesson will teach you how to use three different texture filtering methods. It also teaches you how to use a keyboard to move objects in a scenario and how to use simple light in an OpenGL scenario. This course contains a lot of content. If you have any questions about the previous course, first review it. Before ente

You do not have to take a class or a class in order, but you should take it seriously in every class. You can take a look at it in English ...... You can upload it on his website or tell me (zwqxin.com) to your behalf (Khan )
