Hiya,

[Don't know whether to post this to infoviz or to another topic thread, but here goes]

I'm mapping some data about cell metabolization to dot densities, using nested loops, where D is a density stepping value, e.g.:

for (int i=0; i<100; i=i+D){  
for (int j=0; j<100; j=j+D){
           point (i,j);  
}
}

By increasing or decreasing the value for D, I can change the dot-density in the area. Simple stuff. The tricky bit is that I have an array of 25000+ datapoints for D and  for the best user experience, I want to animate through the array as fast as computationally possible.

Is this a sensible approach, or should I use lerp()? Is there a better approach to representing a dot density that I haven't thought of?

Extra credit: does P bog down under big arrays? If so, should I break up the data set into manageable chunxx?

Thanks!

PS to Ben: Nice dissertation.
