Member Function Documentation

virtual std::shared_ptr<transformation> bnb::interfaces::transformation::chain_right ( const std::shared_ptr< transformation > & t ) const

pure virtual

Applies transform t after this e.g.

{rotate >> translate;} rotates first: (initial -> rotated) >> (rotated -> translated) = (initial -> translated)

virtual std::shared_ptr<transformation> bnb::interfaces::transformation::inverse_j ( ) const

pure virtual

Get the inverse of the transformation.

Exceptions
