apply_transform()

VariantTransform celeritas::apply_transform	(	VariantTransform const &	left,
		VariantTransform const &	right
	)

Apply the left "daughter-to-parent" transform to the right.

The resulting variant may be a monostate (identity), translation (no rotation), or full transformation.

The resulting transform has rotation

\[ \mathbf{R}' = \mathbf{R}_2 \]

and translation

\[ \mathbf{t}' = \mathbf{R}_1\mathbf{t}_2 + \mathbf{t}_1 \]
