Detailed Description

A class to represent a hierarchy of tranform. It is designed for efficiency, that is when using transform(), the full hierarchy is not re-evaluated . Instead the resulting transformation is maintained by push() and pop(), using a stack to guarantee exactness when pushing/popping.

Constructor & Destructor Documentation

TransformatorHierarchy (   )

Create an empty hierarchy equivalent to identity transform.

void pop (   )

void push (  const Transformator &  t  )  [inline]

void transform (  const float *  src, float *  dst )  const [inline]

Apply the sequence of Transformator pushed in the hierarchy by applying it in reverse order, that is last pushed first. The src and dst vectors can be the same (temporary values are used).

void transformByInverseTranspose (  const float *  src, float *  dst )  const [inline]

Apply the sequence of Transformator pushed in the hierarchy by applying it in reverse order, that is last pushed first. Inverse transpose are used. This function should be used when transforming normals.
