Him I am trying to replicate this water droplets all around the tap, so maybe a
series of droplets every 12 or 24 degrees around z axis. How should I do. that?
I know it is a beginner trick, but I am trying different #while sentences and it
doesn't seem to work out. Could somebody help me? Here is the code I am using to
achieve the droplets look like a trajectory.

Thanks in advance for any help,


// FUENTE SUPERIOR

#declare posX = 0.02;
#declare posY = 0.82;
#declare dy = 0.055;
#declare posZ=0;
#declare posZ= <0,0,posZ+12>;


    #while (posX < 0.3)
    sphere {
    <posX,posY,0>, 0.01
    material { agua }  }
    #declare dy = dy - 0.01;
    #declare posX = posX + 0.02;
    #declare posY = (posY + dy);
    #end

I think if you look at code used to model the physics of a falling object, or
better yet, a bouncing ball - you will get the deceleration on the upward
"bounce" and the acceleration on the subsequent fall.


Attached, find a scene I wrote to do the bouncing ball, hope it helps - ask if
you have any questions.

Thank you so much m@b, that was exactly what I was looking for. What if I wanted
to continue drawing my droplets in the lower level of the fountain? Where should
I declare the distance from the Y axis so that the droplets appear as a
continuation of the upper level?

Thank you in advance for any help

You could just add a second sphere and translate it before rotation:

#declare Rotation=0;
#declare Rotation_angle=12;


#while (Rotation < 360)
     #declare posX = 0.02;
     #declare posY = 0.82;
     #declare dy = 0.055;
     #while (posX < 0.3)
         sphere {<posX,posY,0>, 0.01 pigment{rgb<0,1,0>} 
       rotate<0,Rotation,0>}
         sphere {<posX,posY,0>, 0.01 pigment{rgb<0,0,1>} 
translate<0.2,-0.3,0> rotate<0,Rotation,0> }
         #declare dy = dy - 0.01;
         #declare posX = posX + 0.02;
         #declare posY = (posY + dy);
     #end
     #declare Rotation = (Rotation + Rotation_angle);
#end
