Sets an object so that camera can automatically fly to the current position from now on.
1. Set a position. You can place a cube that displays its position in front of it. You can also write a script to set the location here.
2. Use Functions
Mobile function transform. Position = vector3.slerp (positionstart, positionend, time * 0.001 );
Rotation function transform. Rotation = Quaternion. slerp (startrotation, aimrotation, time. Time * 0.00001 );
3. Add a function in the switch script

performance issue discussed here: scanning speed.
Using a triangular ranging method, the camera screen can recognize the laser point and calculate the actual distance. for desktop computers, it is almost considered that time is not required. Then, the factor limiting the scanning speed is the camera's detection rate. For common USB cameras currently in the market, the maximum frame rate is 30 FPS in 640 × 480 resolution mode, so the scanning speed is

"Diablo 3" is a large number of players welcomed the large-scale games, most of the Mac users can be very smooth play "Diablo 3", but still some of the old model users can not run smoothly. To solve this problem, today Xiao-bian introduced some of the "Diablo 3" optimization methods.
The first thing to be clear is that the player can press control+r in the game to display the game frame rate (FPS). For Diablo 3, the average frame rate above 30FPS can

The settings in the Encoder window will directly affect the video's quality, sound and bitrate.
Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size; If you want to make a video smaller, you can

Redis Data Bulk Import Export
One way to do this is to export and import Redis data from one server to a new server in a work-redis-dump tool, but he needs to install a ruby environment, and there may be unexpected errors in the installation environment. So I have to choose another way. A few ideas for reference.
1, data export, do not write themselves, and do not use third-party scripts,

two full screen images? How much FPS is saved? This method is called the reverse painter algorithm. However, the reverse painter algorithm is not used casually and must support Z-buffer. And, most importantly, the Z-buffer sequence should be set correctly. For example, if a overwrites B, the Z value of A is smaller than B, that is, a is more advanced, and then the normal draw order is reversed, we achieved our goal of optimization.
At this point, som
