The volumetric rate is generally used in real estate development, which refers to the ratio of total floor area and total land area in the land, and this parameter is a very important index to measure the use intensity of construction land. In other industries, the calculation of volumetric rate is also very important, such as product utilization, pipeline utilization and so on. So in the monitoring system, how can vivid image of the expression volume

Twilight, Hello! Rainbird sent you a short message: has written a lot of background running deamon. With a very handy, but I now want to get the pipeline passed over the content, do not know how to achieve, similar to echo "AAAA" |a.php,a.php how to get echo content, do not know what you have. Today received a message, the solution of the method for everyone to share: In fact, the Shell's | It actually represents the standard output of the previous on

Cocos2d (v.3.0) rendering pipeline Roadmap Why (the vision) The way currently cocos2d does rendering is good but it is beginning to feel somehow antiquate and moreover it doesn't actually leverage modern multi core CPUs so popular labels on most modern tablets and mobile phones. So we want to RE design Cocos Renderer, for making it more faster Ming, elegant, scalable, flexible but still simple to use and to understand. also we want to maintain that s

, many stream cores are executed in parallel. Each stream core processes a vertex's vs shader computing. From our vs shader code, we can know that it mainly performs space conversion. // Change the position vector to be 4 units for proper matrix calculations.Input. position.

Reprinted please indicate the source is klayge Game Engine Deferred rendering has been around for a long time in klayge. I have also written a series of articles to describe delay rendering in klayge. In the klayge 4.0 to be launched, deferred rendering enters the core of the rendering system and can be used as a more general and convenient rendering encapsulation. In terms of functions, the deferred rendering in klayge 4.0 has also made great strides. This series will focus on analyzing these

Introduction This White Paper provides a technical explanation for direct3d application developers on how to set the parameters of the direct3d transformation pipeline by the direct manipulation of direct3d matrices. Overview Direct3d uses three transformations to change your 3D model coordinates into pixel coordinates (screen space). These transformations are world transform, view transform, and projection transform. World transform controls how mode

Recently, I am reading the artech WCFArticleI am very familiar with some of his articles on IIS and ASP. NET ISAPI. At the same time, I made a summary of IIS and ASP. NET HTTP runtime pipeline by referring to other materials. After reviewing the process of IIS processing Asp.net resources, the following figures are roughly drawn to deepen understanding. For more details, see several articles by artech: http://www.cnblogs.com/artech/archive/2007/09/0

I haven't written integration for a long time, probably because there are not many writeable items, I can only get farther and farther if I write more. Originally, this topic could be called "smart pipeline-the next concept that can be hyped on the Integrated Platform. Low-key and low-key. -- First, enter an advertisement. As many high-tech products are popular today, this advertisement uses film or animation plus narration. The following text may be

Dizzy, it took a long time to complete the required volume texture (32x32x32 texture, I used PS to make a t_t), and found that content pipeline does not support velume texture !!! After searching in the Forum, Ms people said "I agree it's a shame we didn't have time to get these into the content pipeline, but sadly they were among the specified features that just didn't fit into the schedule. "-_-#. Well, a

OpenGL rendering pipelines are divided into two parts: modelview transformation and projection transformation ). As a metaphor, computer graphics development is just like taking pictures. The purpose is to present the real scene on a photo paper. The process of observation and transformation is like setting the camera position, selecting the desired object, and setting the shape of the object. The projection transformation is just like the camera displaying real 3D scenes on the photo paper. Let

Article contentContinue with the contents of the previous chapter, get the instance through HttpApplicationFactory's getapplicationinstance static method, and then execute the BeginProcessRequest method of the instance to perform the remaining HTTP Pipeline operation, the code is as follows:IHttpHandler app = httpapplicationfactory.getapplicationinstance (context); So what exactly did getapplicationinstance do with this method? Is it just a new object

The simplest way to communicate with Linux processes is through anonymous pipelinesThe creation of anonymous pipelines requires the use of the pipe function, the pipe function parameter is an arrayrepresents the file description word. This array has two file description words, the first one is to use athe file descriptor for the read data The second is a file descriptor for writing data. You cannot use a file descriptor for write read operation or read file descriptionIdentifier write operati

memory. The complete program that can run on R600 consists of two parts: a program that runs on the host (CPU), a program running on the R600 processor, part of the program called the shader program when processing graphics applications, and a program called Kernel when the GPU is used for general computing.Figure 1This section is all from the AMD manual "R600 instruction Set Architecture".2.

Talking to the pipe above, you can communicate between the processes that are related.How do I communicate with unrelated processes? This article will talk about named pipe FIFO.First, the conceptNamed pipe FIFO, which provides a path name associated with it, stored as a file in the file system.One process opens in R, and the other program opens in W to create a pipeline between two processes.By using a FIFO file as the medium, you can enable any two
