Differences between local illumination and Global Illumination

Local illumination (local illumation) simply refers to the illumination effect from the light source to the model surface. Global illumination) simply put, Ray Tracing and Radiosity are used to calculate the global illumination of all surfaces and light sources in the environment, the effects and shadows of light passing through the glass, as well as the shadow generated by simulating precise Direct Illumination, Radiosity, calculate the amount of light emitted by each element on each surface,

How to become a professional programmer-three years of programmer's career

technically competent. In fact, testers consider the problem from the customer's perspective. They can often consider scenarios that many developers cannot consider. There is a set of well-developed theories for testing. If the R D personnel can understand some testing methods and theories, it will be of great help to the software design.Professional programmers must be excellent testers. Vi. design height EncodingIt is a bit abstract to stand on the design height code, but it is indeed the mo

Two methods for taking infrared photos with a Sony 707 or 717 digital camera

be said that this time is rare, unless you take a camera to take a picture of the midday sun! Determine whether your digital camera can take infrared photos Almost all cameras can take infrared photos, but how can you be sure that your camera has the ability to take infrared photos? Here is an effective method. Generally, almost all digital cameras have the ability to take infrared photos. digital cameras use CCD or CMOS, which have the ability to receive infrared rays. CCD has a higher infrare

The experimental results show that the statistics of granular micro-images can achieve a comprehensive, objective, convenient and automatic effect, and can be applied to the statistics and analysis of various micro-images, it is highly practical.References[1] research on micro-image acquisition and analysis system of Rice Pollen particles in Xin Li, Hu MahaI, Zhou shaoguang [J]. application optics, (1): 43-45.[2] Yu Sai, Yu Huimin, Liu Yuanyuan. met

Java reflection and java reflection

concept. It may remind us of the concept of reflection in optics. Although computer science has given a new meaning to the concept of reflection, in terms of phenomena, they do have some similarities that help us understand. In computer science, reflection is a type of application that can be self-described and self-controlled. That is to say, this type of application uses a mechanism to describe and monitor its own behavior, and according to its own

Amazon vs Google cloud services

had direct business dealings with Amazon. Currently, companies that support Google's computing engine include cloudscaling, which currently supports both Amazon and Google APIS; rightscale, as one of the pioneers in the cloud service management and monitoring field, the company became the first distributor of Google's computing engine in February this year. Let's face the reality. Although Google is currently facing some credibility issues, the removal of Google Reader has surprised many peo

ABC knowledge talk about lens and lens focal length

. After a 28-105mm lens is attached to the multiplier, the zoom range becomes 56-210mm (shown below ). Close up (close up) is connected to the front of the lens. In fact, it is a positive lens that can increase the horizontal magnification (that is, the ratio of the image to the object size) during shooting ). Currently, most DC (except DSLR) lens headers cannot be replaced. Therefore, in DC, these accessories are added to the front-end of the lens, such as doubling the additional mirror and Wid

Analysis of OpenGL software simulation of light

simulating it, let's first analyze the relationship between the light and the surface color of an object in the Real World: Illumination Model in reality What is the color? In the understanding of people who have never learned optics, color is the property of an object. The color of many objects remains unchanged. For example, snow is white, leaves are green, and blood is red. But if we try to stay in a dark hut isolated from any light, we will find

Fingerprint Recognition Principle

performed on the feature data of the acquired fingerprint image and the fingerprint feature data stored in the database, calculate the similarity and obtain the matching results of the two fingerprints. Then, identify the user based on the matching results. In short, the fingerprint recognition technology first reads the fingerprint image, then uses the computer recognition software to extract the fingerprint feature data, and finally obtains the recognition result through the matching recognit

Allow the console to output color logs for Windows

It is often seen that many of the output of some open-source software (such as when ndk is compiled and started by the operating system) is color, which makes it easier to identify which are important and enhance readability.CodeAs follows: # Include the yellow macro is red or green based on the three primary colors of optics. In addition to the foreground color, you can also set the background color. You can see other similar parameters as defi

MATLAB Implementation of K-means clustering algorithm

The principles of clustering and classification in data mining are widely used. Clustering means unsupervised learning. Classification means supervised learning. Generally speaking, clustering is classified as unknown samples, but is classified as similar classes based on the similarity of samples. When classification is a known sample classification, the sample features and classification features must be matched to classify each sample into a specific class given. This article describes th

that you can make good dishes. Whether you can make good dishes is still dependent on your ability to stir fry, stir fry, and stir fry every day.So what I want to emphasize here is that you cannot just look at any information you have collected, but you must organize, classify, and create a new structure by hand, this process of information collection and processing is even more important than the final summary of written text.What is "Learning "?

number of nodes in the network and large data traffic, you can apply for multiple ADSL lines to speed up the Internet access and improve the stability and reliability of the entire network, backup function. Optical fiber access is good, and the speed is fast, but when there are more users, it is easy to drop the line. ADSL is a dedicated optical fiber access and ADSL access, the access speed is stable and independent from the number of online users. I have a friend's Internet cafe (60 machines)

What is Google Fiber worth the attention of operators?

business model that Google can develop. 2. Optical Fiber zone business case Google's method of constructing fiber optics is an alternative. Google asked the community to organize the desired services rather than building as expected. Under normal circumstances, new entrants in the market can earn about 15% of the market share, while Google's self-selection model is doing even better, and it can also cut the construction costs of traditional fiber-to-

Four Methods for connecting networks to the Internet

). Note that the IP addresses of the two APS must be in the same CIDR Block and the same channel can be used to achieve wireless connection and resource sharing between the two wired LAN networks, or expand the wired network. It should be noted that both APs adopt oriented antennas. Opinion 2: Use optical fiber Many netizens have agreed to this solution, because the current price of fiber optics is also more than 10 pieces per meter, and the cost of

Camera calibration under C #

calibration, robustness is not high.3. Camera Imaging Model: The image is the reflection of the space object through the imaging system, that is, the projection of the space object on the image plane. The gray level of each pixel in the image reflects the intensity of the reflected light on the surface of the space object, and the position of the point on the image is related to the geometrical position of the corresponding point on the surface of the space object. The relationship of these pos
