Member Function Documentation

template<typename T>
Transform3 LinAlg::Transform3< T >::rotation (  const Vec3< T > &  axisAngle  )  [inline, static]
 

Return a rotation transform of axis.length() radians about the unit vector in the direction of axis.

Note:
This clearly won't work very well for integer types T.

template<typename T>
Transform3 LinAlg::Transform3< T >::rotation (  const T  angle,
const Vec3< T > &  v
)  [inline, static]
 

Return a rotation transform of angle radians about the unit vector axis.

Note:
This clearly won't work very well for integer types T.
