First to show you the effect of the picture:
In the shopping site, the function of adding a shopping cart is a necessary function, and some sites when users click to add a shopping cart button, it will appear that the merchandise from the click Out to the animation of the parabola to join the shopping cart, this feature looks very cool, the user experience also has some improvement. The following describes the implementation of the add-in-cart

Opencascade conic to bspline curves-parabola
[Email protected]
Abstract.Rational bezr curve can represent conic curves such as circle, ellipse, Hyperbola ,. etc. but how to convert a conic curve to bspline curve is still question, I. e. represent a conic curve in bspline form. parabola curve is the most simple conic curve, that the parabola does not require ratio

Parabola added special effects animation for shopping cart (support IE7 above, mobile side performance is good)1. Refer to a minimal jquery plugin library2. Start the set start point and after completion callback function1.

Before sharing the "golden finger" implementation of the parabola between two points, then a friend asked me, in general, will give the speed, how to simulate the natural trajectory.I hear this is not very easy to achieve, according to the previous formula, two points between the time is constant, the trajectory is determined, that is, the average speed is constant.Then in turn, at a given average speed, and then by distance/velocity, the time can be

To achieve a parabolic animation, you must know the parabolic equation, which is the function of mathematics, if the parabola of the graph:
According to the equation of the parabola, it is known that any three points ca

1, the use of line tool to make a ray, using Point tool in the ray to take a little f.
2, select the ray endpoint and ray, select "Construction"-"vertical". To perpendicular to the line of parabola, using point tools in the vertical take a point k, with line-segment tools to connect KF.
3, select the line of KF, select "Construction"-"midpoint" constructs a midpoint e, select the E point and line KF, select "Construction"-"ve

constant, and the formula becomes:

Y= (100000* (GetHeight () -20))-(vy*t–5*t*t*20000)/100000;
GetHeight () in the mobile phone to get the height of the screen. Okay, let's see what happens when you use this formula (NOKIA 7650 emulator or Unijava emulator)
Figure 1
This is a parabolic trajectory at a 45-degree angle.
Do not feel the height is not enough! The operation is not accurate! So we add an offset on Y to increase the height, and the formula changes to:
x= (Vx+windspe

I personally think that iterator and yield implement the same functions, but iterator must be implemented in the class, and yield is implemented in the real function, both of which will save the status.
The generator is also implemented by the iterator.

Iterator
An iterator is an object attached to the iteration protocol. It basically means that it has a next method. When called, it returns the next item in the sequence. When no project can be returned, A (raise) StopIteration exception is thrown.
The iteration object allows a loop. It retains the state (location) of a single

With a deep understanding of the Python Generator (Generator), we can simply create a list using the list generation method, but the list capacity is limited due to memory restrictions. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majority of elements is wasted.
