OpenGL ES programming guide for iPhone OS -- Introduction
"OpenGL on iPhone OS" provides an overview of OpenGL ES and how it is integrated into the graphics subsystem on the iPhone.
"Determining OpenGL ES capabilities" describes how to select the version of OpenGL ES andTo make your app stable on each iPhone.

There are many ways to process images on a computer or mobile phone, but the most efficient method so far is to effectively use the graphics processing unit, or GPU. Your phone contains two different processing units, CPU and GPU. The CPU is a versatile operator and has to deal with everything. The GPU can concentrate on one thing, that is, perform floating point operations in parallel. In fact, image

OpenGL ES dynamically blends the filled color between vertices with the texture color of the triangle ing part. In this case, you also need to adjust the buffer size and vertex_size constants (for example, (2 + 4 + 2) * 4 ). To tell OpenGL ES vertices to contain texture coordinate data, call
Recently began to contact the Elasticserach database, so want to install a practice practiced hand in the virtual machine, installed time but a lot of time, Baidu has a lot of tutorials, but the tutorial too much too messy, afraid of their easy to forget, so record, but my main record is to install the ES database how to open, As for the others, I would like to recommend the tutorial I read.First of all must be installed
Vertex data, also known as vertex attributes, refers to each vertex data. Refers to the data that can be used to describe each vertex, or a constant value that can be used by all vertices. For example, you want to draw a cube triangle with color. You specify a constant value for all three vertex colors of the triangle. But the three vertex positions of the triangles are different, you need to specify a vertex matrix to store three position values.specifying vertex attribute DataVertex property d

1. How do I draw a triangle with OpenGL es?
Write a class implement renderer interface, implement Ondrawframe method, Onsurfacechanged method, onsurfacecreated method
Write a class triangle class, define fixed-point coordinates, load all vertex coordinates, call a gldrawarrays method of GL10 to draw a triangle
Finally, call triangle.drawself in the overridden Ondrawframe method to actually draw the triangle

There is no password problem with the es file browser. How to set the password?
In the es file browser, if we set a password, it is relatively good for some privacy in our files, therefore, we often hear that the elasticsearch file browser does not have a password. Next I will explain what to do if the elasticsearch file browser does not have a password and how to set a password for the elasticsearch file
[Ityran original]iphone OpenGL ES shows one of 3DS max models: obj file format AnalysisYuezang-ityranIn iOS 3D development, it is often necessary to import a model generated from 3D design software such as 3DS Max. Because OpenGL ES cannot read these files directly, it is often necessary for developers to add interfaces to import them. It is common practice to import and control in OpenGL
making objects move according to a preset program, such as a rotating triangle, can draw attention. But what if you want users to interact with your OpenGL ES graphics? The key to making your OpenGL ES app Touch Interactive is to extend the Glsurfaceview, Ontouchevent () method to listen for touch events. This tutorial shows how to listen for a revealing event and let the user rotate an OpenGL

Qt has built-in support for OpenGL ES. It is very convenient to use Qt for OpenGL ES development. Many helper classes are available. A QWindow class has been added since Qt 5.0. This class can be used to draw 3D graphics using OpenGL or QPainter to draw 2D traditional GDI + graphics. qglwidgets earlier than
