In OpenGL programming, the calculation of the 3D model vertex method vector is very important, and it directly affects the display effect. I am not familiar with OpenGL for a long time, for a long time, I have been confused about the problem of normal vector computing. After careful research and finding some information, I basically realized the algorithm of normal vector computing. The following is a summary, hope to help beginners.We all know that i
SQL Server date calculation
Generally, you need to obtain the current date and calculate some other dates. For example, your program may need to determine the first or last day of a month. Most of you probably know how to divide a date (year, month, day, and so on ), then, just use the split year, month, and day to calculate the date you need in several functions! In this article, I will show you how to use the DATEADD and DATEDIFF functions to calcul
In the key chain schedule method, after WBS decomposition, task period estimation, and task chain and key chain identification are completed, feeding buffer and project buffer must be added ). The connection buffer can avoid delays in the entire project because tasks on non-critical links cannot be completed on schedule. The project buffer is used to ensure that the project is completed on schedule.
According to goldratt, the author of the key chain method, and some other authors, if the buffer

Comparison of Two Algorithms for calculating natural logarithm, calculation logarithm AlgorithmIntroduction
Some time ago, I wrote two essays about algorithms used to calculate the natural logarithm, using the elliptic θ function-arithmetic geometric mean and the Taylor series expansion. What is the performance of these two algorithms? The following statements are provided in reference [3:
The elliptic method above is the elliptic θ function-arithmet

The measurement value of 172.19.10.0 on this vro is 3. The calculation method is as follows:
Cost Value of f2/0 of the data forwarding interface of RT11 "1" + cost value of f2/0 of the data forwarding interface of RT12 "1" + cost value of vlan1 of the Target Interface
Originally a foreign source (technicalanalysisengine src 1.25) internal calculation of the EMA is:var copyinputvalues = input. ToList ();for (int i = period; I {var resultvalue = (Copyinputvalues[i]-returnvalues.last ()) * multiplier + returnvalues.last ();Returnvalues.add (Resultvalue);}var result = new Emaresult (){Values = Returnvalues,Startindexoffset = period-1};It is evident that such calculations are inconsistent with our tradition and may not

1. PrefaceIn the process of natural language processing, it often involves how to measure the similarity between two texts, we all know that the text is a high-dimensional semantic space, how to abstract it, so as to be able to stand in the mathematical perspective to quantify its similarity.With the measurement of similarity between texts, we can use the K-means of partition method, density-based dbscan or model-based probabilistic method to analyze the clustering of text. On the other hand, we

In the process of numerical programming, it is often necessary to use the calculation of floating-point numbers, but the addition and subtraction of floating-point numbers is usually error-based. The specific problem code is as follows:Double begin = 0.0; Start positionDouble end = 20.0; End Positionint k = 2; The kernel function supports a multiple of radiusDouble Initialdis = 0.1; Initial distance between particles (required to preserve consistency
This paper introduces the normal projection process of the Cartesian coordinate system from the Earth coordinate on the ellipsoid plane. This paper studies how to transform the geodetic coordinate, the length and direction of the geodetic line and the azimuth angle of the geodetic plane. This paper focuses on the principle and method of Gauss projection, solves the problem of conversion from spherical to planar, and solves the coordinate conversion of adjacent belts.Overview of Gauss projectionT

PHP reverse Polish representation and expression calculation ????? Speaking of expression computing, I think of a joke. I introduced to him that our PHP development framework has a class that uses RPN to parse and calculate formulas. As a result, he smiled and told me nothing. In addition, it also lists a series of evidence that using the EVAL function in PHP can solve all problems .???? Maybe you will agree with this old man. It doesn't matter. You c
