Absrtact: First, a basic image scaling algorithm is given, and then the speed and scaling quality are optimized step-by-step.
High-quality, fast image scaling full text is divided into:On the nearest neighbor sampling interpolation and its speed optimizationMedium two-time linear interpolation and three convolution interpolationThree linear interpolation and mipmap chains in the next chapter

Today, in the "Add/delete programs", we finally found a text editing software, Leafpad, which is extremely similar to notepad in Windows. Another one is Mousepad. I haven't

The code files for Hello world are directlystored in the project directory. Let's take a look at the file composition of the project in detail below.1. "Resource" This directory is primarily used to store resource fil
object motion. Frame-by-frame animation is also known as frame animation or key frame animation, that is, the effect of motion is achieved by displaying the image sequence of the animation at a frame or frame. Based on different visual spaces, computer animation can be divided into two-dimensional animation and three-dimensional animation ." -- Also from reference 1
We are mainly studying real-time animation. In fact, the simple point is the animation calculated in real time, instead of the ori
Android to display the corresponding frame.This is a little troublesome. We know that we have five frames, each of which is 30 pixels. We define a rectangle. Its width is one frame, and its height is the height of the image.

Let's start our project. We need the knowledge of the previous chapters, mainly game loop and graphic display content.
We need an object to do the action. We use elastic, so I created the class of Elastic. j
difficulties. The main difficulty is to cope with unstable networks. In a mobile network, it is usually prone to network instability, Connection Reset, and reconnection due to disconnection. On the one hand, frequent reconnection requires overhead to establish a connection. On the other hand, especially when the GPRS/2G/3G/4G switch occurs, the bandwidth may have a bottleneck. When the bandwidth is not enough, the content with a higher frame rate or a higher bit rate is difficult to send out, w

After the image resources are loaded, call the initialize method of the game object and determine whether the game loop object exists. If yes, end the previous loop (in this case, the level is usually switched, when a new game object is introduced). Otherwise, the game loop is established and started.
Now let's take a look at the implementation code of the game loop:

7. Graphics settings-refreshing Rate
Update Rate
The refresh rate and the number of frames per second are not confused. FPS indicates how fast your video card can output independent frames per second. The refresh rate is a separate attribute of the CRT display: the number of refresh times per second, no matter how many frames the video card has or what type of images w
capacity of vertex transformation coloring is limited.(2) Maximum number of vertices.(3) create a triangle.(4) grating restrictions.(5) pixel coloring restrictions.5: the memory size is too small.6: video card memory is too small, and other hardware caps restrictions. The above is the bottleneck in the common 3D graphics rendering pipeline, so we will determine the bottlenecks one by one. The simple method is to detect FPS.Note 1: many bottlenecks may change due to hardware changes.NOTE 2: the

The primitive turn-to-peer system has largely been abandoned in many other types of modern games. Let's take a look at the network model of
