TGeoTrap Class Reference

TRAP is a general trapezoid, i.e.

one for which the faces perpendicular to z are trapezia and their centres are not the same x, y. It has 11 parameters: the half length in z, the polar angles from the centre of the face at low z to that at high z, H1 the half length in y at low z, LB1 the half length in x at low z and y low edge, LB2 the half length in x at low z and y high edge, TH1 the angle w.r.t. the y axis from the centre of low y edge to the centre of the high y edge, and H2, LB2, LH2, TH2, the corresponding quantities at high z.
