Hi rooters,

How to do the 3-d zoom?

I mean that if I have the CAVE 100x100x100 but I need to display just the
zone 1x1x1 around the vertex with the coordinates x,y,z - how to make
the 3-d frame 1x1x1 with nesessary offsets where I can draw the
tracks&hits?

The class TMarker3DBox(x,y,z,a,b,c) seems to be desiged for this but if I
just do

root> TMarker3DBox *b=new TMarker3DBox(-21.,26.,27., 4.,4.,4.,0.,0.);
root> b->Draw();

it makes just the empty canvase.

Is TMarker3DBox able just to show the small box inside the already
existing plot of my big cave of I do something wrong?

Best regards
Valeri
