OpenGL coordinate conversion (good text-clear version)

The following article details the conversion of coordinates in OpenGL, which is clear and unambiguous. But the so-called rendering pipeline includes only Modelview transformations and projection transformations, which I think is not the case. That's just the angle of the coordinates. For example, what vertex coloring, rasterization, sent to the frame cache are not involved. Original address: http://blog.csdn.net/zhulinpptor/article/details/5897102 1.

The limit of CPU and RAM is obtained in the case of no disk bottleneck.7, Memory table, select a from T1 where non-indexed field = ' xx ', using different size of T1 table, observation. Observing conditions in non-indexed cases8. Change the 7 field to an indexed field, and the index file is in memory.

Bayesian, probability distribution and machine learning

Java tiger is extinct, therefore, the probability of P (Java tiger | hairy animal) is also 0. Prior Probability Distribution Estimation When the variables are continuous during observation, a prior distribution is often required to obtain the probability of a certain hypothesis in the hypothesis space, which is not present in the sparse data set. For example, if there is a large, even metal disc, ask the probability that the metal disc will fall

Hawking: we are close to answering the question of where humans come from.

starting point of nature. However, a fundamental change occurred in 1920s when Edvin harp began to use 100 inch of the telescope for observation on the Wilson Mountain. We found that the stars were not evenly distributed across the whole space, but instead gathered in a mass group called Galaxy. By measuring the light from the galaxy, we can determine their velocity. He expected as many galaxy to fly to us as they would fly to us. This is expected in

a breakpoint. Second, run the program again. When the program stops at the set breakpoint Use various tools to observe the program status. After the program stops at the breakpoint, sometimes we need To further observe the flow of the program, we will introduce Settings, how to control program running, and the use of various observation tools. 1.3 How to set breakpointsIn VC, you can set multiple types of breakpoints. We can break these breakpoints i

Sub-operations can use this counter to achieve high-level abstraction, such as primitive synchronization. Fast: the performance of zookeeper is more powerful, especially when reading, because zookeeper service can be provided by many machines at the same time and read speed is 10 times higher than the write speed; Data Model and multi-level namespace Zookeeper multi-level namespace: The Z

, and the superficial culture he obtains from tradition and environment. The uniqueness of man lies not in the surface, but in the complete liberation of the content of consciousness, which is common to all mankind. So he's not a person. freedom is not a reaction, freedom is not a choice. Man deceives himself to think that because he has a choice, so he is free. Freedom is pure observation, no direction, no fear of return and punishment. Freedom is n

Glsl projective texture

Projective texture is an important basic technology. Although it can be easily implemented in the era of fixed pipelines, projective texture can be flexibly used in the era of programmable pipelines, it is a basic operation to achieve a variety of advanced effects. Of course, its own effect is also very "cool". In addition, for "Shadow Mapping", which is not a new technology ", projective texture is a required operation. It is to project the depth texture (depth texture) obtained from the

Acoustic model Acoustic models in speech recognition make full use of the information of acoustics, phonetics, environmental characteristics and speaker sex accent to model speech. In the present speech recognition system, the implicit Markov model (Hidden Markov model,hmm) is used to establish the posterior probability of a certain speech feature vector sequence for a certain state sequence. Implicit Markov model is a proba

. The design pattern in NET Five: Observer mode

The Design Observer pattern (Observer) perfectly separated the observer from the observed object. For example, the user interface can be used as an observer, the business data is observed, the user interface observes the changes in the business data, and when the data changes, it is displayed in the interface. One of the principles of object-oriented design is that each class in the system focuses on one function, not the other. An object does only one thing and does it well. The observer patter
