because it can be directly compiled into machine code, it can do the bottom-level optimization, such as the use of internal functions and embedded assembly language.In addition, C + + to do parallel computing is relatively easy, for example, can be directly used Cuda. However, there are many problems in C + +, such as slow and error-prone compilation links, lack of support for common features in other languages, low development efficiency and so on. But C + + has also been developing, believing

m just in the middle of L and V, that is H.NBSP; D is the normal distribution function (NDF), and on most surfaces, the direction of Microfacet is not evenly distributed. The closer the normals of the microfacet to the normal of the macro surface, the smoother it becomes. This distribution is defined by the normal distribution function D (m) of the Microfacet. function d () determines the size, brightness, and shape of the specular highlight. Normal distribution functions generally have parame

The concept of reflection was first propos

operations.The problem in reality: the operation of complex numbers-------Many children's shoes may have forgotten what a plural is. Let's first say what is plural (Optics Valley's learning to old live to old)　　　　A plural is a number a+bi that can be written as follows, where a and b are real numbers, and I are imaginary units. In complex A+bi, A is called the real part of a complex number, B is saidis the imaginary part of the complex number, I is c

format original piece, the right side is the camera processing after the compressed JPG picture. Raw and JPG contrast So, if you're going to start taking pictures, change the camera format to raw and take the initiative in your own hands. Second, to get to the point There are a number of software parsing RAW format, the mainstream Adobe acrlightroom, the optics Pro 9 of Freescale's capture One,dxo, where I use Lightroom to demonstrate

absorption and reflection of the material to different wavelengths of light, or diffuse reflection. Here I will not say more, interested students to find Physics department optics teacher to ask, people have been studying this problem for a lifetime. More interested students can go to the physics Department of the professor to discuss the light of the wave-particle duality, and then study the human eye on the optical feeling, and then study the surfa

, this kind of structure server needs to have very large memory, when the system memory is sufficient, can alleviate the pressure of disk read operation, when the memory is low, the system will use virtual memory, the frequent use of virtual memory will increase the disk I/O increase, resulting in increased CPU consumption, and again affect the performance of the Web server. And network bandwidth is also a factor restricting high concurrent access, when the traffic is very large, the network ban

colours are called "complementary colors" when the two shades of light in the optics are suitably proportioned to produce a white sensation. Complementary color is the most powerful color combination of hue, therefore, the rational use of complementary colors, can be a good contrast, highlighting the theme. We can make reasonable arrangements for the saturation, purity and size of the two colors to achieve harmony and unity. With a good complementar

can not use the general MB and Mbit conversion relationship (1b=8bit) to convert. For example, the official internal data transmission rate of a product is 683mbit/s, at this time can not simply think that 683 divided by 8 to get 85.375, it is considered that 85mb/s is the internal data transmission rate of the hard disk. Because in the 683Mbit also contains a lot of bit (bit) of auxiliary information, not exactly the hard disk transmission data, simple with 8来 conversion, will not be able to g

compare the advantages and disadvantages of xDSL, HFC and FTTX access technology. For:XDSL technology is to use digital technology to transform the existing analog telephone subscriber line, so that it can carry the broadband service. Low cost, easy to achieve, but the bandwidth and quality of the large difference.The biggest advantage of HFC networks is its wide frequency band and the ability to take advantage of cable networks that already have considerable coverage. To transform an

category of copper for a data center cabling system to 6 categories, which are defined as Wanchaodo mode OM3, OM4, or Single-mode. When it comes to fiber optics, as a new generation of wiring products, it's faster and less disturbed by the outside world. But can optical fiber become the inevitable trend of next generation wiring, and replace copper? Although the fiber is more advantageous in speed and security, it will be complementary to the copper

melting, the impact is not small, because we study people, education accounted for all the main part of life. The enrichment and expansion of academic content is proportional to the enrichment of the content of life. ” There is no better language than the master suggested to the students, young designers are the most not affected by too many environmental, open-minded, full of passion and good ideals of a group, adhere to your ideals, to become top designer efforts. 　 Cross-border is curren

Based on optics, the image measurement technology, which integrates optoelectronics, computer technology, laser technology, image processing technology and so on, has formed a new measurement technology in the field of measurement, and the image measurement system based on digital image processing technology has been widely used in the measurement of geometrical quantity, aviation and other remote sensing, Micro-dimension measurement and appearance me

precision and anti-fouling dual revolutionary breakthrough! The illumination of optical system is higher; The traditional optical mouse's light spot shape is relatively sparse, and the maximum illumination is only 1000Lux, while the ghost hidden wave intensity reaches 54400Lux, is 54 times times of the traditional optical engine, from the technical data analysis can be "phantom hidden Ghost Engine" Technology is more technologically superior than the past. To ensure that the mouse tracking mo

The pattern is suggestive of its dual-lens design. It is reported to be equipped with 5.2? 1080p screen, Kylin 950,3g/4g memory, 32GB storage, 1200W dual camera. Standard version of the price of 3088 yuan, a high version of 3688 YuanHuawei P9 adopts dual camera design, and it is equipped with the sensor com

Using near-loop (extension tube) Near-loop is one of the inexpensive options, its principle is simple, that is, the distance between the lens and focal plane, creating a magnifying effect. The different thickness of the close-loop has different amplification effect, many times to see the near-loop is a group of three of the way to sell. Because the close loop is actually just a cylindrical ring, there is no optical structure inside, so ... Buy a deputy factory can be (but the more expensive OEM

there is an excess, the upper and lower lining lines are obvious, but the middle lining is slowly masked by the mask, and the text uses a shadow, which conforms to the background of the dark green to reflect the white font above. The middle made a relatively light gradient, very friendly to reflect the three-dimensional. The edge of the page body is also lined, to find it carefully Then below is the use of the upper lining line, with shadows instead of the three-dimensional button desi

Based on the previous analysis, we concluded that modulation can be used for list link blue methods:By lowering the blue channel color level to reduce the overall saturation of the color (for example, adjusting the #0000ff to #000099), to avoid darkening, and black confusion, we can also increase the levels of other primary color channels and a
