Hi Rooters,
I am a beginner with the ROOT system, so it may be a well-known question.
I tried to draw the small part of setup. When the cave rounded the detectors
is drawing the distance between detector looks correct relatively to the
detector size (Left canvas). But when the cave is not drawing or it was
totally
excluded the visible distance between detector looks wrong in comparison to
the detector size (Right canvas).
I am using Windows NT, SP6a and ROOT 2.23.11.
The next file (d2.C) has been used.
#include "TRoot.h"
void main()
{
TBRIK *cave = new TBRIK("cave", "CAVE", "", 80., 80., 80.);
TBRIK *det1 = new TBRIK("det1","Detector 1", "", 0.001, 5., 5.);
TBRIK *det2 = new TBRIK("det2","Detector 2", "", 0.01, 10., 10.);
TNode *pcave = new TNode("pcave", "PCAVE", cave, 0., 0., 0., 0);
pcave->cd();
TNode *pdet10 = new TNode("pdet10", "Pdet10", det1, 30., 0., 0., 0);
TNode *pdet11 = new TNode("pdet11", "Pdet11", det2, 60., 0., 0., 0);
TNode *pdet20 = new TNode("pdet20", "Pdet20", det1, -30., 0., 0., 0);
TNode *pdet21 = new TNode("pdet21", "Pdet21", det2, -60., 0., 0., 0);
TCanvas *c1 = new TCanvas("c1", "Detectors", 10, 10, 500, 500);
pcave->SetVisibility(1);
pcave->Draw();
TCanvas *c2 = new TCanvas("c2","Details", 600, 10, 500, 500);
c2->cd();
pcave->SetVisibility(2);
pcave->Draw();
}
