OpenGL ES is a subset of the OpenGL three-dimensional graphics API designed for embedded devices such as mobile phones, PDAs, and game consoles. OPhone currently supports OpenGL ES 1.0, OpenGL ES 1.0 is based on the OpenGL 1.3 specification and OpenGL ES 1.1 is based on OpenGL 1.5 specification. This paper mainly intro

2010-04-01This article collects a set of OpenGL ES series tutorials.
There are a series of OpenGL ES development tutorials on www.play3d.net. It is a rare tutorial to go from basic concepts to advanced programming. This site reposted all the articles for your study and reference.
Basics of OpenGL
OpenGL ES software hierarchical stack. This chapter introduces the calling hierarchical stack of OpenGL ES in Android systems, and analyzes in detail how to implement API call association between libraries through hooks, let us understand the dependencies between libraries. This section describes OpenGL ES in Android. Introduction to OpenGL

OpenGL ES coloring language is two closely related languages. These languages are used to create a shader on the programmable processor of the OpenGL ES processing pipeline. Unless otherwise stated in this document, a language function applies to all languages and is generally used as a language. Specific languages will point out their target processors: vertext or fragment ).

OpenGL ES tutorial for Android-Part IV-adding colors
January 14th, 2010 by Per-Erik Bergman-Android,Embedded
Last tutorial was about transformations. This tutorial will be a short one. I'm going to talk about adding color to your mesh. I will continue with the source code from tutorial II.
This tutorial is about coloring.
Adding color
3D models with no colors are pretty boring so let's add some color to it. in general colors need no explanation. openG
The graphics example of apidemos contains the OpenGL ES example. OpenGL ES is mainly used to develop 3D graphics applications. OpenGL ES (OpenGL for embedded systems) is a subset of OpenGL 3D graphics APIs. It is designed for embedded devices such as mobile phones, PDAs, and game hosts.
The following is an introduction to OpenGL
Android OpenGL ES plotting tutorial 3: Drawing GraphicsAfter defining the shapes to be drawn by OpenGL, you certainly want to draw them. Using OpenGL ES 2.0 to draw a graph may require more code than you think, because the API provides a large number of graphic rendering pipeline control interfaces.This chapter describes how to use OpenGL ES 2.0 API to draw the s

The Ppb_graphics3d is a 3D graphical interface chromium exposed to PPAPI, similar to the EGL of the Open GL and local windowing systems. We use the Create meth
OpenGL ES provides 7 steps for caching data:1. Generate Glgenbuffers ()--Request OpenGL ES generates a unique identifier for the graphics processor-controlled cache.2. Bind Glbindbuffer ()--tells OpenGL ES to use a cache for the next operation.3. Buffer Data Glbufferdata () or Glbuffersubdata ()--let OpenGL ES initiali
This is my entire process of log analysis for haproxy in the unit.We have been in the maintenance ES cluster configuration, and did not put a set of processes including the collection end of the code, all their own once, and the online collection of logs when we generally use the logstash, but the industry many people say logstash whether it is performance and stability is not very good, The advantage of Logstash is the simple configuration, this time
The following are all converted from the android game programming entry-level classic. For more information, see the source.
Use glcolor4f () to set a global default color for all vertices. But sometimes more fine-grained control is needed (for example, you need to set the color for each vertex ).
OpenGL ES provides this function. All you need is to add the rgba floating point component to each vertex and tell OpenGL
OpenGL es Shader language variables and data types (i) (Official document fourth)all variables and functions must be declared before they are used. Variables and function names are identifiers .Without a default type, all variables and function declarations must contain a claim type and an optional modifier. Variables are declared in the first place to indicate the type, followed by a number of variables, separated by commas. In many cases, a variable

After the ES stream passes through the PES packager, it is converted into a PES package.

After defining the shape to be drawn with OpenGL, you may want to draw them on the screen. Drawing these shapes based on OpenGL ES 2.0 requires a little more code than you think, because the 2.0 API provides a lot of control over the image rendering pipeline. This section describes how to use the OpenGL ES 2.0 API to draw the shape you have
OpenGL ES introduction OpenGL-ES is a cross-platform, fully functional API for 2D and 3D graphics applications free of license fees, it is mainly designed for a variety of embedded systems, including consoles, mobile phones, handheld devices, household appliances and automobiles. It consists of a well-defined subset of desktop OpenGL, creating a flexible and powerful underlying interaction interface between
OpenGL ES 05-texture ing our rectangle
I have decided to introduce texture ing in advance because it may be easier to map a texture to an object instead of facing a multi-faceted (or 3D object ). In addition, it seems that this is the most desired knowledge for iPhone OpenGL ES programmers, so I will insist on Texture ing until now.
I know that I have skipped many details supported by OpenGL, so that you c
