question about vrayDisplacement subdivisions

[Morbid Angel]

last night i was trying to calculate smoothing algorythim and... well I figured that the way meshsmooth works is it takes 1 poly and divides it into 4 on iteration 1, on iteration 2 it takes recieved number from iteration 1 and divides that into 4 and so on.
Im wondering tho, what kind of equasion it is to be able to calculate 256 subdivisions?

I dont know off the top of my head how to do it in one calculation.
But going by your theory of how meshsmooth works, this is the polys after meshsmoothing a single poly 30 times
1,152,921,504,606,846,976
Basically as you said each iteration is 4 times the polys of the previous. So 256 times would be definitly not doable

:P lol...

The subdivisions is the number of polys you get along a single edge of the original triangle; those are multiplied by 2 on each subdivision step, and they go 1, 2, 4, 8, 16, 32, 64, 128, 256 etc. 256 subdivisions would mean 8 recursive steps of subdividing.
