learn opengl

First, we will briefly introduce OpenGL: As one of the mainstream graphics APIs, OpenGL has superior features in some cases than DirectX.1. closely integrated with C.OpenGL commands are initially described using C language functions. For those who have learned C language, OpenGL is easy to understand and learn. If you

final Texture unit color based on the texture coordinates, and combine these colors with the color of the dot element or the color calculated based on the illumination to output the final color of the pixel. In the following tutorial, we will see that the Texture unit can contain different data and implement many special effects. OpenGL supports 1d, 2d, 3D, cube, and many other textures, which are used in different technologies. First, we will

Bring up graphics processing and graphics-related content, especially when playing computer games (usually installed) Many people are not easy to think of a familiar noun called direct X, usually what direct 9.0c and other things are necessary to play the game. So, do you know what Direct X is? Besides, do you know a noun like OpenGL? This article will briefly introduce and contrast them, hoping to learn m

Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently. > OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we

. Algorithm All of them have detailed descriptions, which will help you understand more deeply. 5. http://www.gametutorials.com/ I contacted the earliest OpenGL tutorial website and had many special tutorials, such as a small 2D RPG tutorial. Unfortunately, most of the Code cannot be downloaded for free now. 6. http://www.ozone3d.net/tutorials/index.php There are tutorials on OpenGL, glsl, and direct3d, as

Speaking of programming, there are probably a lot of people think of TC's # include But have you ever wondered how those fancy PC games were written? By the TC, the poor 640*480 resolution, 16Color to do it? Obviously it's not going to work.The purpose of this post is to let everyone give up the old interface of the TC, let everyone touch some new things.OpenGL, one of the most popular graphics APIs, has features that are superior to DirectX in some situations.1. Close integration with C languag

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

The beginner OpenGL person and I have the same feeling, read so many OpenGL books just let me add Glu GLUT glew GLFW These things exactly what is it? We learn OpenGL and OpenGL has nothing. We must be very puzzled.I learned three months of

the next section will be difficult to learn.In this section, you can learn about The concept of mesh OBJ Model data format OBJ model simple load class and load experiment Expression of the modelIn 3d graphics processing, a model is usually made up of one or more mesh (meshes), and a mesh is an independent entity that can be drawn. For example, the complex character model can be divided into the head, limbs, costumes, weapons and

OpenGL lets programmers do not have to take into account the various display card underlying operation is the same problem, the hardware is communica

length. For example, join us starting with "X", 5 values ahead, we will fall on the next "X" value. Starting from "U" is also the same, but also the number of 5 forward. This parameter is a byte unit, not a floating point unit, so we must multiply the number of bytes by the float type.The last parameter, Glvertexattribpointer, is an "offset" parameter. This parameter needs to know how many bytes from the beginning to the first value. The start is XYZ, so the offset is set to NULL to indicate "t

Lesson 1Expansion, cropping, and loading of TGA image files: In this lesson, you will learn how to read OpenGL extensions supported by your graphics card and display them in your specified cropping area.This tutorial is difficult, but it will help you learn a lot. I heard a lot of friends ask me about extensions and how to find them. This tutorial will be handed
