Chapter 2 EGL Interface
EGL is an interface between OpenGL ES and the underlying native platform Windows system. This chapter mainly describes the egl api of OpenGL ES, how to use it to create context and draw surface, and makes comparative analysis on other Windows APIs fo
BKJIA quick translation] One of IBM's current goals is to make it easier for developers to write JavaScript-based user interfaces without using the JavaScript language itself.
The company launched Enterprise Generation LanguageEGL community edition CE), an Eclipse-based development tool designed to simplify JavaScript development.
Although egl ce is relatively new, it comes from IBM's Rational Business Developer (RBD) solution, which has been commerci
In Android, The egl/gles library is not directly linked at runtime, but is selectively loaded according to configuration during the first use. More specifically, the libegl. So file contains a "Loader" that will try to load the hardware graphics library or the software graphics library (libagl ). Loader'sSource codeLocation: frameworks/base/openl/libs/EGL/loader. cpp. The library to load depends on the conf
EGL is a set of platform-independent APIs provided by khronos group. Its functions:
1> communication with Native Windows system;2> query available configurations;3> Create a drawing surface available for OpenGL ES );4> synchronize rendering between APIs of different categories, for example, between OpenGL ES and openvg, or between OpenGL and the drawing commands of local windows;5> Manage "rendering resources", such as rendering map ).

Specifies whether the fixed point data value should be normalized (gl_true) or converted directly to a fixed point value (gl_false) when accessed. If normalized is set to gl_true, it means that the value of the integer type is mapped to the interval [ -1,1] (signed integer), or the interval [0,1] (unsigned integer), and conversely, the values are converted directly to floating point values without normalization.

Before entering the GUI system, we recommend that you read the "Opengles" section in the application of this book and see the official OpenGL ES Guide. Because the Android GUI system is based on OPENGL/EGL to achieve, if there is no basis for the analysis of the source code may be "less effort."

Curl error: Problem with the ssl ca cert (path access rights ?) .
Here is the CA problem: first, the CA that issues the server certificate is okay, so it should be a problem with the ca-bandle.crt that curl uses, this means that you have deleted some files in the/etc/pki/tls/certs/directory or set invalid permissions.

At the early stage of Ubuntu10.10 development, the Ubuntu Technical Committee considered not to support the suniscsi and IntelIA64 Cert architectures. Now the technical committee has voted to pass the decision: to abandon the support for both the iSCSI and IA64 architectures.
