opengl rotate

OpenGL usage in MFC (2) -- derived OpenGL class, mfcopengl Sometimes OpenGL needs to be configured every time, which is a little troublesome. You can directly derive an OpenGL Class Based on CWND and use it directly when necessary. The following is an example of this class, which deletes some specific items of my proje

OpenGL Development Environment configuration in vc6.0 (required for OpenGL) Step 1: select a compiling environment Now {Tagshow (event, 'windows ');} "Href =" javascript:; "target =" _ Self ">WindowsThe mainstream compiling environments of the system include Visual Studio, broland C ++ builder, Dev-C ++, and so on. They all support OpenGL. But here we choose VC +

Chapter 4 (Lecture 3rd) Example 24 -- OpenGL rendering function, 24 -- opengl Category: C #, Android, Baidu map application; date: 1. Introduction The Baidu map SDK provides open OpenGL interfaces for developers to help developers achieve more flexible style painting on maps and enrich the experience of map use. Ii. Running Introduction: This section describes ho

OpenGL is an open source graphics library that can develop two-dimensional graphics software or three-dimensional graphics software. Many well-known applications have been developed based on OpenGL, such as the famous Artoolkit and Unity3d.Glut is the OpenGL Application Toolkit, known in English as OpenGL Utility Toolk

about how to obtain the complete source code of the blog, see the article. The main difference from the previous Code is that we started to consider the Z axis coordinates. Here we use (0.0, 0.0, 1.0) to indicate the direction of the Z axis. If we do not rotate, the Z axis is facing us. It is a point projected onto the screen and we cannot see it. So here we make a little rotation and adjust the Z axis to the lower left, this angle is in line with th

My system for Ubuntu14.04, with Apt-get installed the implementation of OpenGL MESA,QT is the official website to download the run file to install.OK, now two are all there, so try to write OpenGL code under QT.Before trying to paste the code in vim and then compile, the test succeeds is a statement containing one of the following compilation options.1 GCCBut directly paste the code into the QT creator Clic

OpenGL getting started [5]Today I want to talk about the content of 3D transformation. The course is boring. This is mainly because many functions cannot describe their effects when they are used independently. I have to give a comprehensive example at the end. I hope you can see it in one breath. Reading only once may not be enough. If you feel confused, read it twice. If you have any questions, follow the instructions below.I have also used several

Multiple sampling in OpenGL and multiple sampling in OpenGLMultiple sampling in OpenGLOne of the biggest advantages of anti-sawtooth processing is that it can make the edge of the polygon smoother and make the rendering effect more realistic and natural. Point-and-line anti-sawtooth processing is widely supported, but unfortunately, the smooth processing of polygon is not implemented on all platforms. In addition, even when GL_POLYGON_SMOOTH can be us

OverviewThe geometry data-the vertex position, and the standard vector (normal vectors)-can be changed by vertex operations (Vertex operation) and basic combination operations before the OpenGL pipeline raterization process.Object coordinatesThe local coordinate system of the object-the original position before any transformations. In order to transform (transformation) These objects, you can call Glrotate (), Gltranslatef (), Glscalef () these method

To use OpenGL ES to draw images in Android applications, you must create a view as a container. The more direct method is to derive an implementation class from GLSurfaceView and GLSurfaceView. Renderer. GLSurfaceView is a container drawn using OpenGL. GLSurfaceView. Renderer is used to control the drawing action. For more information about these classes, see the OpenGL
