我的做法如下:
1 做圆弧,R=176,A=359
2 FOG ,如下:
if x>=0 and x<=0.5 {y=24}
else if x>0.5 and x<=(215/360) {y=24-(12*(360*x-180)*(360*x- 180)/35/35)}
else if x>(215/360) and x<=(250/360) {y=12*(250-360*x)*(250-360*x)/35/35}
else if x>(250/360)and x<=(290/360) {y=0}
else if x>(290/360)and x<=(320/360) {y=12*(360*x-290)*(360*x-290)/30/30}
else if x>(320/360)and x<=(350/360) {y=24-(12*(350-360*x)*(350-360*x)/30/30)}
else if x>(350/360)and x<=1{y=24}
