|
|
// A G4Paraboloid represents a solid with parabolic profile with possible
|
|
// cuts along the Z axis.
|
|
//
|
|
// Member Data:
|
|
//
|
|
// dz z half lenght
|
|
// r1 radius at -dz
|
|
// r2 radius at dz
|
|
// r2 > r1
|
|
//
|
|
// Equation for the solid:
|
|
// rho^2 <= k1 * z + k2;
|
|
// -dz <= z <= dz
|
|
// r1^2 = k1 * (-dz) + k2
|
