Is there a way to take a given path in povray and animate each of its
individual vertices according to seperate paths? For example pathA has
vertice 1, 2 & 3 - have vertice 1 follow pathB, vertice 2 follow pathC and
vertice 3 follow pathD.

I'm trying to visualize a maze/pathfinding algorithm and I would like to be
able to continiously animate each point. (example here:
http://www.mydis.org/wp-uploads/growths.mpg)

input greatly appreciated,

mike

I also should ask, is there a way to instantiate/insert path verticies at
certain times of the clock (if clock > something and < something else)
insert new point in path. My animation below is simply inserting cubes at
specific times of the clock and not yet using paths.

thanks,

Hello Mike,

If you are talking about splines (though I'm not at all sure from your 
description that you are), then yes there is.
You can declare a number of splines then use them to build another spline 
and you can add in spline positions based upon the clock setting.
The following (slightly messy) example illustrates both.

Regards,
Chris B.


camera { location <0,2,-2> look_at 0 }
light_source { <-5,30,-10> 1 }
#declare MySplineA =
  spline {
    cubic_spline
    -.25, < 0,0.3,-1>
    0.00, < 1,0.3,0>
    0.25, < 0,0.3,1>
    0.50, <-1,0.3,0>
    0.75, < 0,0.3,-1>
    1.00, < 1,0.3,0>
    1.25, < 0,0.3,1>
  }

#declare MySplineB =
  spline {
    cubic_spline
    -.25, <0,0,-1>
    0.00, <1,0,0>
    0.25, <0,0,1>
    0.50, MySplineA(clock)
#if (clock > 0.5)  0.60, MySplineA(clock-0.5)  #end
    0.75, <0,0,-1>
    1.00, <1,0,0>
    1.25, <0,0,1>
  }

#declare ctr = 0;
#while (ctr < 1)
  sphere {
    MySplineB(ctr),.25
    pigment { rgb <1-ctr,ctr,0> }
  }
  #declare ctr = ctr + 0.01;
#end

Chris, you answered my question(wrt "splines") perfectly!

Thanks soo much,
