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
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 (OpenGL for Embedded Systems) is a subset of the OpenGL three-dimensional graphics API designed for embedded devices such as mobile phones, PDAs, and game consoles.
The API is defined by the Khronos Group, Khronos is a graphic hardware and software industry association that focuses on open standards for graphics and multimedia.
Build a basic framework for 3D development in Android:
First, import OpenGL
other device of the same screen, we can use software emulation to zoom in, but it can be slow and unbearable. With mixed mode scaling, you need to create an OpenGL ES texture and render the picture (320x240) onto the GL quadrilateral.
Textures will be scaled to fit the screen size (1024x768) and your game performance will be significantly improved.
From the perspective of implementation, this process can be described as follows:

When you want to use this VBO then Glbindbuffer () its bufferid, which generally put vertex data (including the model of XYZ and texture coordinates UV), in addition to the premise is already compiled and set up the shader program 2. Using VBO ren
1, open My Computer, find to share the hard drive, I here to e-disk for example!
2, right click E disk, click Properties, and then click Share.
3, in the above figure, click Advanced Share-Share this folder-OK
4, download and install ES file browser.
5, and then open the ES Manager, find the LAN page, point Scan, you will find my computer, such as Figure!

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

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

OpenGL ES 2.0 implements a programmable graphics pipeline that is complex and flexible compared to 1.x fixed pipelines, consisting of two parts of the specification: the OpenGL ES 2.0 API specification and the OpenGL ES coloring language Specification. The following figure is the OpenGL

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
The previous article describes several basic geometries that OpenGL ES can draw: points, lines, triangles. Examples of these basic geometries will be presented separately. For the sake of convenience, these geometries are plotted on the same plane for the time being, and after the coordinate system and coordinate transformations of OpenGL ES are introduced later, a true 3D graphics rendering method is intro
