For Loop - Vops

[kubabuk]

Sorry for such a lame question, but I can't find anywhere, any example of how for loop in vops works. Could any one give a very simple brief how should I deal with that. I am thinking about moving each time a grid plane by one unit.

thanks

Hi Kubabuk,

I'm pretty sure you don't need a loop to move points by a certain amount every frame, but here's a simple example of a ForLoopVOP. It's the equivalent of:

surface test () {
   float v = 0;
   int   i;
   for(i=0;i<10;i++) {
	  v += 1.0/10.0;
   }
   Cf = v;
}

If you render the "Mantra" ROP and set mplay to "inspect", you should see a value very close to 1. (0 + (1/10)*10 = 1).

To do it in vops you need to put the incrementing value outside and feed it into the forloop vop.
