Copy/设置pscale大小

(资料图)

floor(fit01(rand(@id*3+34),1,15))  id随机

fit01(rand(@id),0.8,1.2)根据id 随机大小   

@pscale = fit01(rand(@id),0.1,0.2)*0.005;

stamp("../copy1","scale",0)  大小

fit01(rand(stamp("../copy13","my_id",0)*5.5+3),0,360)+fit01(rand(stamp("../copy13","my_id",0)*5.5+3),0,360)*$T/2*stamp("../copy13","my_num",0) 旋转

根据速度删除点length($VX,$VY,$VZ)>18（需要查看速度大小）

根据时间求余$F%2     

ID层v@CID={1,0,0};     Attribute Wrangle

根据年龄控制空气阻力

airresist *=fit01(@nage,1,10);   根据随机idairresist *= fit01(rand(@id),1,5);

控制速度大小@v*=0.5; 

接入端口`opinputpath("..",2)`  

@Timelnc:帧速率(1SPS.4帧1秒)

根据Cd属性删除（移除）粒子

if(@Cd<0.3)

removepoint(0,@ptnum);

根据点序号属性删除（移除）粒子

if(rand(@ptnum)>chf("thredshold"))

removepoint(0,@ptnum);
