About Simulationg關於計算

For the golf ball’s simulation, we need to know the golf ball’s flying direction and speed, and the spin(back spin and side spin) for the trajectory in the air. After the ball drops on ground, wen need to know what the material is to calculate the bounce. If the ball is dropped on rough or sand, the ball’s bounce will surely be less compared with dropped on grass or green.

How do you simulate in rough sand?

For our own DTG golf game, we will let you know what types of surface is the ball is currently on: green, grass, rough, sand.
If your 9 iron’s full swing’s carry(not including bouncing and rolling) is 90 yards, your will find your 9 iron’s full swing will be less if you swing on rough, and even lesser if you swing on sand. Our DTG software will make some comprosation by the type of surface that the ball is on.
我們的DTG軟件於落地時會提示目前落地的材質:果嶺/短草/長草/沙坑, 我們的系統並沒有提供不同的模擬草皮,因此使用者必須自行修改揮桿力道,例如落到長草區你用9號桿要打出你一般於發球區的90碼距離, 就得比你一般揮桿的速度再加快一些,才能於長草區打出90碼。

What’s DTG simulate software’s green speed?

Our green simulation speed is about 9.5 feet by Stimpmeter Reading.

What’s your accracy?

First , please note that we are not able to simulate all surfaces of every course. So only the carry is meaningful when talking about simulator accuracy. Since different course’s grass types will affect the bouncing factor.
For  DTG-201 model, the horizontal angle is +-1.5 deg, and the vertical angle is about +-2 deg, and the speed/carry is about +-5%. 
首先, 沒有一台模擬器能模擬所有球場的草地/沙坑。因此準度一般以空中飛行距離為主,因為彈跳/滾動都與場地相關。
以DTG-201為例, 左右方向誤差在1.5度以內,仰角比較大些在2度以內, 速度/空中飛行距離在+-5度以內。
