no, it;s not exacly what I ment, the voxels is in fact Yours suggestion, I 
ment something bit different. Now i'm rendering few tests, it's almost 
clear that in meany cases using my little idea improves speed about 50%, 
full examples + sources will be place soon (one test without optimization 
renders 5 h  iwanted even tests to look nice ;)
