Thank you.
My idea is only useful for animation. To speed up the data transfer very large.
Parents and children do not interest me.
Earlier you wrote me that well write:
sphere{}
sphere{}
sphere{}
than the cycle "for (i=0;i<3;i++)..."

I am most interested in triangles.
I will try to deal with the povray-master/source/core/shape/mesh.h
