I wrote a demo to simulate the elastic collision of small balls and posted it first. Scenario Description: Randomly generate n balls, random initial speed, initial direction, quality, size, and color. Each ball is regarded as a particle. The collision between the ball and the ball, the ball and the wall is elastic (I .e., after the collision, the X and Y axes are reversed, and the size remains unchanged), and kinetic energy conservation.

The first article briefly introduces the spring cloud architecture, and my side of the current common needs of most enterprises, including the selection of technology is more stringent, harsh, not only to use the industry's most popular technology, but also with international standards, in the next 5-10 years can not out. As the architect of the company, we should also have a vision of the world, not only to give the company a good selection of technology, but also to quickly respond to business

); } To give you an example, see orbitdraw.as, draw a track line, you can get some interesting patterns. Elastic motion You might want to use elastic motion as another particle of gravity. Yes, the elastic movement is my favorite! Recall the example of spring chain and elastic motion between objects in the eighth chapter. Later we will see a wider range of applications, where the particles are moving in an elastic motion, like those in the gravitat

Several fitness evaluation functions are given, and the graphical representation is given. The first few days of the virus, reinstall the system, accidentally the program all formatted, crying!!! No way, a lot of programs are missing, now put these several typical functions rewritten, give them out, even if the particle swarm algorithm is an end! Hate virus!!!! The first function: The Griewank function, the graph looks like this: The fitness func

To make a more cool UI effect, you typically add a particle effect to the UI. However, unlike a purely 2D UI animation or spine, particles are created in the scene, and there is a problem with UI interspersed. This article explores how to change the sortingorder of a special effect or UI to avoid interspersed.Pre-conditionsFirst, the type of canvas is the foundation of everything, and the canvas I use is Screen-Space that all the UI is illuminated by

between the segment and the paragraph to add a new point. It is worth noting that the use of cubic, that is, this brings a sense of nonlinearity. This method also ensures that all previous control points are on the curve, so it does not change the position of the points on each integer frame.The interpolation method is this, and then the other is used in the spark of a very practical problem, that is the problem of the number of points instability. The method mentioned above must be based on th
