OpenGL ES Tutorial for Android-Part III-Transformations January 1st, 2010 by Per-Erik Bergman-Android,Embedded Last tutorial was about building your polygons. this tutorial is all about transformations, how to move the polygons around. I will continue this tutorial from where the previous ended so you can use that source code or make a copy of it. The previous tutorial details how to create a polygon. This tutorial describes how to move and transform

To be precise, OpenGL is called the high-performance graphics algorithm industry standard. Write all to open graphics library. It is the most widely accepted 2D/3D graphics API in the industry. Is a specification that defines a cross-programming language and cross-platform programming interface. It is used for three-dimensional images (two-dimensional ). Applications: CAD, content creation, energy, entertainment, game development, manufacturing, pharm

They often make a lot of puzzles, so that beginners and some practitioners have a variety of rumors ab

This article translated from: http://developer.android.com/guide/topics/graphics/opengl.html The Android system includes OpenGL (Open Graphics Library), which provides high-performance support for 2D and 3D graphics, especially OpenGL ES APIs. OpenGL is a cross-platform graphics API that specifies a standard software interface for 3D graphics processing.

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

OpenGL coordinate system can be divided into: World coordinate system and current drawing coordinate system.World coordinate system : In OpenGL, the world coordinate system is at the center of the screen as the origin (0, 0, 0), and is always the same. You facescreen, your right side is the x positive axis, which is the y positive axis, and the screen points to your z-axis. The unit of length is determined

OpenGL ES is usually used on Android to display the rendered results on the screen, sample processing, model display, and so on. In this case, you only need to use the Glsurfaceview class and the renderer class provided in the Android API to set/write the appropriate code in the initialization, callback functions provided by these two classes. However, if you do not want the rendering results to be displayed on the screen, which is called off-screen r

Explain the csdn writing the code end of the articleThis course is about drawing simple geometries, before actually drawing, let's familiarize ourselves with some concepts.Point, line, and polygonWe know the concept of a bit, line, and polygon in math (specifically, geometry), but these concepts are different in computers.Math point, only position, no size. However, in a computer, no matter how the computational accuracy is improved, it is not always possible to represent an infinitely smallPoin

Labels: d3d OpenGL cross-platform You blue ocean (http://blog.csdn.net/you_lan_hai) The difference between DirectX 3D and OpenGL Coordinate Systems brings us a lot of trouble and puzzles new users of cross-platform programming. Recently, I was playing a cross-platform game. I carefully checked the matrix between the two and found that there is no big difference. I can pass the matrix of the left-hand d3d s

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 more about Direct X and

OpenGL State Machine Use the state machine mechanism in OpenGL to store the current state of OpenGL. The so-called OpenGL state Machine is also a set of state sets of OpenGL. There are some states that can be turned on or off and can be opened with the glenable (Glenum capab

Overview Cocos2d-x underlying implementation relies on OpenGL, This is a graphics library, can operate the graphics card, therefore, in the processing of more complex games, the consumption of a large game, the processing efficiency will be very high. The canvas tool provided by Android cannot provide this efficiency because it does not directly operate the video card. Of course, some of the drawing tools provided by android can be used for simple gam

In Lesson 1, I teach you how to create an OpenGL window. In this lesson, I will teach you how to create a triangle and a quadrilateral. We will use it to create a gl_triangles triangle and gl_quads to create a quadrilateral.Based on the code of Lesson 1, we only need to add the Code during the drawglscene () process. Next I will rewrite the entire process. If you plan to modify the code of the previous lesson, you only need to overwrite the original d
