Class for transformation of 3D geometrical objects. It allows different translations, rotations, scalings and reflections. Several specialized classes are derived from it:
TranslateX3D, TranslateY3D, TranslateZ3D, Translate3D,
RotateX3D, RotateY3D, RotateZ3D, Rotate3D,
ScaleX3D, ScaleY3D, ScaleZ3D, Scale3D,
ReflectX3D, ReflectY3D, ReflectZ3D, Reflect3D.
The idea behind these classes is to provide some additional constructors for Transform3D, they normally should not be used as separate classes.
Example:
Remark: For the reason that the operator* is left associative, the notation
is much more effective then the notation
In the first case three operations Transform3D*Vector3D are executed, in the second case two operations Transform3D*Transform3D and one Transform3D*Vector3D are performed. Transform3D*Transform3D is roughly three times slower than Transform3D*Vector3D.

void HepGeom::Transform3D::getDecomposition | ( | Scale3D & | scale, |
Rotate3D & | rotation, | ||
Translate3D & | translation | ||
) | const |
Decomposition of general transformation. This function gets decomposition of the transformation in three consequentive specific transformations: Scale3D, then Rotate3D, then Translate3, i.e.
scale | output: scaling transformation; if there was a reflection, then scale factor for z-component (scale(2,2)) will be negative. |
rotation | output: rotation transformaion. |
translation | output: translation transformaion. |
