In this case, we will briefly animate the motion Picture (animation). Just like the cartoon principle, the essence of animation is to use the visual persistence of the human eye, quickly transform the picture, resulting in the illusion of the object in motion. For the Three.js program, the implementation of the animation is also achieved by redrawing the screen several times per second.To measure the screen switching speed, the concept of fps (Frames
There are many optimizations for the project, such as mesh merging, reducing drawcall and model bones and physical calculations, merging material balls, optimizing code, etc.

Now more and more people are trying to use HTML5 for development, and HTML5 engines are also increasing. What kind of engine should Developers choose? This time I will compare the efficiency of several engines I personally think are not bad.

video card for processing, which is a waste of Bandwidth Resources, at the same time, the video card also performs a large number of operations on the undisplayed part, which is a waste of hardware resources. After the optimization of the tree, you can crop the tree to obtain the vertex data of each display area. Only this part of data is transmitted to the video card, which can significantly improve the display speed. Irr has implemented all these optimization functions through the eight-Tree
number of frames transmitted in one second. It can also be understood as the number of frames that a graphic processor can refresh several times per second. FPS (frames per second) is usually used). Each frame is a static image, and the rapid continuous display of frames forms the illusion of motion. A higher frame rate allows you to get smoother and more realistic animations. The more frames (FPS) each se
rate.By definition, the frame rate is the number of frames (FPS) that are played in a second. We can first measure the time t between two pictures and then ask for its reciprocal. If t=0.05s, then the value of FPS is 1/0.05=20.Theoretically so, but how to get this time? Usually the time function of the C language is typically only one second in time, and it must be out of the ordinary. The clock function i

Recent projects into the finishing phase, before the project has done a lot of optimization, mesh merge, reduce drawcall and model bones and physical computing, combined material ball, optimization code and so on, on iOS fortunately, but on Android, tried several mobile phones, from the low to the high end, found that performance is still poor, So it took a few days to explore and finally put the game performance.
