IIIV. # while loop - automatic serial production
With this mechanism it is possible, like in every modern programming language, to do automatic serial productions
in a very simple way.
Here is a sample:
#declare Nr = 0; // start value for Nr
#while ( Nr < 30 ) // as long as the value of Nr is smaller then 30,
//do the following commands:
sphere{<1,0,0>,0.25
rotate<0,Nr * 360/30 ,0>
texture{pigment{color rgb>1,0.65,0<}
finish {ambient 0.1 diffuse 0.85 phong 1.0} } }
#declare Nr = Nr + 1; // increase the value of Nr by 1
#end // this draws a full circle of 30 spheres (Nr.0 to Nr.29)!!!! |
| And this is, what it looks like: |
