Detailed Description

Demonstrates usage of class TEveText - 2D & 3D text in GL.

auto marker = new TEvePointSet(8);
marker->SetName("Origin marker");
Float_t a = 10;
marker->SetPoint(0, a, +a, +a);
marker->SetPoint(1, a, -a, +a);
marker->SetPoint(2, -a, -a, +a);
marker->SetPoint(3, -a, +a, +a);
marker->SetPoint(4, +a, +a, -a);
marker->SetPoint(5, +a, -a, -a);
marker->SetPoint(6, -a, +a, -a);
marker->SetPoint(7, -a, -a, -a);
auto t = new TEveText("DADA");
t->PtrMainTrans()->RotateLF(1, 3, TMath::PiOver2());
// TEveText does not know its bounding box before first rendering.
return t;
