Member Function Documentation

chain_right()

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)

clone_j()

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

pure virtual

Clone the transformation.

Implemented in bnb::transformation.

get_mat_j()

virtual std::vector< float > bnb::interfaces::transformation::get_mat_j ( ) const

pure virtual

Returns 3x3 row-maj transform matrix.

Implemented in bnb::transformation.

inverse_j()

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

pure virtual

Get the inverse of the transformation.

Exceptions

std::logic_error

when matrix is singular

Implemented in bnb::transformation.

transform_point()

virtual point2d bnb::interfaces::transformation::transform_point ( const point2d & p ) const

pure virtual

Apply transform to point.

Implemented in bnb::transformation.
