35 // Class description:
36 //
37 // G4EllipticalCone is a full cone with elliptical base which can be cut in Z.
38 //
39 // Member Data:
40 //
41 // xSemiAxis semi-axis, x, without dimentions
42 // ySemiAxis semi-axis, y, without dimentions
43 // zheight height, z
44 // zTopCut upper cut plane level, z
45 //
46 // The height in Z corresponds to where the elliptical cone hits the
47 // Z-axis if it had no Z cut. Also the cone is centered at zero having a
48 // base at zTopCut and another at -zTopCut. The semi-major axes at the Z=0
49 // plane are given by xSemiAxis*zheight and ySemiAxis*zheight so that the
50 // curved surface of our cone satisfies the equation:
51 //
52 // ***************************************************************************
53 // * *
54 // * (x/xSemiAxis)^2 + (y/ySemiAxis)^2 = (zheight - z)^2 *
55 // * *
56 // ***************************************************************************
57 //
58 // In case you want to construct G4EllipticalCone from :
59 // 1. halflength in Z = zTopCut
60 // 2. Dx and Dy = halflength of ellipse axis at z = -zTopCut
61 // 3. dx and dy = halflength of ellipse axis at z = zTopCut
62 // ! Attention : dx/dy=Dx/Dy
63 //
64 // You need to find xSemiAxis,ySemiAxis and zheight:
65 //
66 // xSemiAxis = (Dx-dx)/(2*zTopCut)
67 // ySemiAxis = (Dy-dy)/(2*zTopCut)
68 // zheight = (Dx+dx)/(2*xSemiAxis)
