Bytes. Understanding the content of coordinate transformation, even if it truly enters the wonderful 3D world. 　　1. display of 3D objects in OpenGL (1) Coordinate System In the real world, all objects have three-dimensional characteristics, but the computer itself can only process numbers and display two-dimensional images. The only link connecting three-dimensional objects and two-dimensional data is coordinates. To digitize the displayed 3D object,

OpenGL sdks on Windows platforms are implemented by Microsoft, and SGI also implements a set of OpenGL sdks. Some friends on the Internet say that SGI's OpenGL is good, so I had the idea of installing OpenGL for SGI, so I had this article.I. Objective: To install SGI OpenGL

Overview of the coloring of the OpenGL ES Shader Language (Official Document chapter II)In fact, OpenGL es coloring language is two closely related languages. These languages are used to create shaders in the OpenGL ES processing pipeline's programmable processor. In this document, unless otherwise noted, a language feature is available for all languages, and gen

3D graphics libraries such as OpenGL allow us to use computers to simulate the visual effects of the real world. With the help of vertices and polygon, we can use computers to simulate the geometric shapes of all objects in reality, with the help of textures, we can use computers to simulate the appearance of realistic objects. However, even with vertices and textures, the 3D world in the computer still does not seem real enough. What is the gap? I th

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 other parts to model, these mesh combination

Author: Nang Lanhai (Http://blog.csdn.net/you_lan_hai) The difference between DirectX 3D and OpenGL coordinate system brings us a lot of trouble and makes the novice of cross-platform programming confused. Recently in a cross-platform game, carefully looking at the matrix of the two, found that there is no big difference, the D3D left-handed matrix passed to OpenGL shader can work perfectly. Let's talk abo

By the TC that poor 640*480 resolution, 16 color 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 A

All the contents of this lecture are packed in a cube, hehe.Hehe, draw a cube, simple ah, we learned the first lesson of the second lesson, will already.Don't worry, the cube is simple, but here's just an example of a cube to illustrate how OpenGL is improving in drawing.Start with a primitive approachA cube has six faces, each face is a square, well, draw six squares on it.Glbegin (gl_quads);glvertex3f (...);glvertex3f (...);glvertex3f (...);glvertex

Introduction GDI draws by device context ("DC"), while OpenGL draws the environment (rendering context "). Each GDI Command needs to be passed to a DC, but unlike GDI, OpenGL uses the current rendering environment (RC ). Once a current RC

OpenGL through the camera simulation, can achieve the most basic three-dimensional transformation of computer graphics, namely, geometric transformation, projection transformation, clipping transformation, viewport transformation, and OpenGL also realizes the Matrix stack and so on. Understanding the content of the coordinate transformation, even if really into the wonderful three-dimensional world.first, t

Opengl basic learning topic (2) vertices, straight lines, and polygon Digress As learning grows, I feel more and more confused. In the previous blog, we recommend that you use a simplec framework based on VS2015 to learn opengl. Some problems. 1. The Release version is not considered in the VS Debug mode. 2. In this version, some Macros in the basic header files of chead and c are poorly designed, such //

1. Decide which version of OpenGL ES you want to support. Currently, OpenGL ES contains 1.1 and 2.0 two versions, with IPhone 3g+ and ipad starting to support OpenGL ES2.0. And the difference between the two versions is very large, not only in the programming mind, the gap between the API is also very large. Therefore, if you want to develop 3D programs or games

Our project is to convert a person's photo into a 3D Avatar. In this case, we need to extract the face contour, obtain the head model based on the photos, and map the human photos and paste them on the model. Our team originally intended to use SFS to get the face model, but after in-depth research, we found that SFS is a very high-end field and difficult, so we decided to first make a common face model, then adjust the face model according to the photo. Since I am mainly responsible for the est

In 3D Scene Rendering, the sky is an essential factor. 3D sky simulation is widely used in visual simulation systems, computer games, and 3D animations. However, there are still many deficiencies in the current simulation of the sky. Some simulation methods have problems such as complicated implementation, computing time consumption, low image resolution, less realistic sense, and only static images can be generated. In this paper, we study the simulated skyAlgorithmBased on the existing 3D grap

1. Reverse sampling When a non-horizontal and non-vertical straight line or polygon boundary is drawn on a Raster Graphic Display, a more or less jagged or tiered appearance is displayed. This is because the straight line, polygon, and color boundary are continuous, and the grating is composed of discrete points. It represents a straight line and polygon on the grating display device and must be sampled in a discrete position. Due to the information distortion caused by inadequate sampling recon

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,
