the mystery of echo cancellation technology. Second, the principle of echo cancellation from the source of communication echoes, can be divided into acoustic echo (acoustic echo) and line echo (lines echo), the corresponding echo cancellation technology is called acoustic echo cancellation (acoustic echo cancellation, AEC) and circuit back Acoustic Cancellation (line Echo cancellation, LEC). Acoustic echo is due to the fact that the sound of the spea

OpenGL (Open Graphics interface)
is a standard application interface for complex 3D graphic design developed by the IRIS GL by SGI Company. The feature is that it can be ported between different platforms, and it can also work in parallel on the client/server system. Efficiency is far higher than direct 3D, so the 3D game developers are preferred to use the 3D API. However, this makes many fine 3D games only support 3DFX Company's Voo

Solid basic knowledge, high-quality code, clear thinking, ability to optimize code, and excellent comprehensive ability are the five main points of programming technology interviews.
Finding a job has always been a hot topic. To find your desired job, you will inevitably need to go through multiple rounds of interviews. Programming interview is the most important part in the interview process for programmers. If you can fully demonstrate your abilities in the programming interview
spaces that lack encapsulation and functionality, and the class is like a living and reliable social member. It has smart services, it has a strong encapsulation barrier and a well-defined interface. Since most people think so, there are only a few methods in your class and public data (this kind of thing exists in a well-designed system !) You should use the struct keyword. Otherwise, you should use the class keyword.

caused by display deviation, Gamma Correction performs brightness correction on the image.

Gfxspeak has a new article "New 123 GB iPad a natural for CAD". For Apple's large-capacity tablet devices, piaoger listened to some comments from the industry and thought it was interesting, and take notes.
1. Industry Leaders
Autodesk:
Autodesk has released a lot of iPad applications, which are the trend in the CAD flat field.
Those in charge of AutoCAD and AutoCAD ws obviously welcome larger flat devices
searchable in SVG images. On average, SVG files are much smaller than JPEG and GIF files, so they are quickly downloaded.
Other non-mainstream image formats:
PCX format
The PCX format is a format developed by zsoft when developing the image processing software paintbrush. It is a compressed format that occupies less disk space. Because the format takes a long time and has the ability to compress and fully color, it is still quite popular.
DXF format
Problem:
When we install CAD, any system (applicable to windows7, Windows2003, and WindowsXP) sometimes "cad fatal error Unable to load ACDB resourcr file" and "cannot start this program because ac1st16 is lost in the computer. DLL, acdb16.dll, and acge16.dll.
Answer:
This is because AutoCAD did not copy the file to the corresponding directory during installation using ACAD. MSI.
